Elan/Praat Machine Segmenting

My number one hated stage in transcription work is segmenting. I would sit there fuming while manually segmenting the recordings I made before I could even start transcribing. It was frustrating because it seemed like something that a machine could to a relatively good approximation of instead of me sitting there for hours doing it for each file!

Luckily, it turns out that between Praat and ELAN, you can very easily have a decent approximation of segmentation done for you.  Not perfect, but it saves HEAPS of time. If you have a ton of recordings to segment into units before you need to transcribe, this is the process for you!

Thank you to T. Mark Ellison for helping out with this heaps.

Praat stage

First load the sound file that you want to segment into Praat (Open > Read from File). Create a Praat Textgrid file based on silences.:

This next part is our best setting after a few trials:

The resulting text grid should look something like this:

The *** is where Praat has segmented for sound. It’s not perfect, but it gives a pretty good shot at things, and you can adjust the boundaries manually in Elan. Save this text grid now.

ELAN stage

Import your Praat text grid:

Cheers Hedvig for letting me know that if you tick the “exclude silences” box, you can have ELAN automatically remove any empty segments from the Praat text file:

Screen Shot 2017-05-05 at 4.15.56 pm.pngAnd you will have your segmented Praat text grid as a layer in Elan looking something like this!

The longest file we tried it on was a 1 hour recording of Samoan (cheers Hedvig Skirgård from Humans Who Read Grammars for providing the file!). It took about 8 minutes for Praat to segment. A 10 minute recording is done in no time.

Now be on your merry way setting up your tiers and transcribing to your hearts content 🙂

Workshop on the Languages of Papua 4

Starting the year with a bang, I made my over to the Workshop on the Languages of Papua 4 held at Manokwari, West Papua, Indonesia! That was 1) my first ever talk at an international conference (debut!), and 2) my first ever time in Indonesia (a pretty niche location, I know). The last workshop was held in 2014, just a bit before I started my PhD. I’d heard good things about it, so was pretty keen to check it out for my self. It did not disappoint!

20170125-manokwari

West Papua gets a bit of a bad wrap as a site of sensitivity re: Indonesia, West Papuan Independence, and things like that. But the city it of Manokwari itself felt very safe, much safer than a city like Daru in Papua New Guinea. Those of us who work on the PNG side were all amazed that the roads were beautifully paved, and that there were motorbikes! We had a great time chilling, and the hosts at the Universitas Papua were wonderful hosts.

View from the water front Cafe Laut at our accomodation, the Hotel Mansinam.

The conference was held across four days, and brought together linguistic researchers who work in the island of New Guinea and the surrounding islands (West Papua in Indonesia + Papua New Guinea). A broad range of topics were covered (which is the way these regionally focused conferences inevitably go), and there seemed to be a good spread of Austronesian and Papuan languages being represented. Topics ranged from grammatical descriptions, language contact, cultural practices, pragmatics…

The talks I personally found super interesting and relevant was the stuff that is coming out of Marian Klamer and her mob over at the University of Leiden. They are working to untangle the complex language history of the Sunda Islands, trying to work through inherited change vs. contact induced change. There was then the familiar work of Russell Gray‘s using ecology to model language diversity, and all the stuff from our usual ANU mob. I don’t know an awful lot about prosodic structure and phonetics of that kind, but I enjoyed the findings of that ilk (here, here) like those presented by Nikolaus Himmelman, and Carlos Gussenhoven.

It was also a nice opportunity to spend some intensive time with fellow fieldworker/Papuanists/people who work in this region – other PhD students, but also finally meeting the Bill Palmer who’s editing a soon-to-be published book about Papuan languages and linguistics… one of the first things I contributed to upon commencing my PhD!

New Fields of Morphology Workshop

As a self-identified sociolinguist (of sorts), I must admit very abstract descriptive linguistics scares me a little bit. This is a problem for someone like yours truly who works on a language with quite complex verbal morphology. But luckily! There are plenty of opportunities around CoEDL and the Wellsprings project to listen in on talks, attend workshops and summer schools. The following is just a short write up of what I got out of it. I find forming a narrative about events like this helps me to remember some of the cool stuff that came out of the workshop, but it also helps to put my own work into perspective,.

20161130

The workshop was great because not only did we get to hear directly from some legendary linguists of various subfields of study (the photo on this post featuring Gregory Stump of the Paradigm-Function Morphology fame!), but also great because they are an opportunity to see the breadth of interest that various linguists have under blunt labels such as “morphology” or “sociolinguistics” or what have you. I may not every become a theoretical morphologist, but it was great to see things like how typological approaches to comparing inflectional paradigms is being tried and tested (Grev Corbett with Canonical Typology, or the Parabank mob of the Glottobank project applying phylogenetic models to inflectional paradigms). There was also cool stuff by Felicity Meakins, Bill Foreshaw and John Mansfield doing corpus work on Australian languages and asking questions of inflection in their respective research languages.

But I guess for me, it was an opportunity to pick up on the kinds of discussions that self-identified morphologists find interesting, and important to figure out. There were a lot of questions on how to best account for complex paradigmatic particularities of individual languages, the relationship between syntax and morphology, ideas that inflectional morphemes may have structures of their own, how sub-paradigms are a thing and how that interacts with syntax (or vice-versa)… A lot of the detailed nuances were a bit beyond me, but it was intensely useful in a quick-and-dirty way to see what is considered important, and I think it’ll help me get a better leg in on describing Nambo’s verbal paradigm (i.e. I’ve now a better idea what to look out for in the data, and where to go in terms of literature for help!)

Cheers to my sempai Matt Carroll for being one leg of the organisation 🙂 (The other being one of my former lecturers Rachel Nordlinger). Tomorrow starts the CoeDL Summer School for more intensive linguisticking, hurrr.

Procedure: DEM+COP Decategorialisation

nqn

Kandra interviewing Wenembu in Nen language, Bimadebn Village. 2014.

Notes for myself regarding a Nen/Nambo study my supervisors and I are working on.

Observation: DEM+COP constructions in Nen and Nambo function as a focus marker of some sorts. The copula verb in these sister languages (seems to?) agree on person, number, and tense, with the A/S argument of the clause. This focus marker, however, appears to be losing it’s agreement as the combined DEM+COP is becoming fossilised/grammaticalised.

Question: Is this grammaticalisation happening at the same rate in Nenland and Namboland? What are the heavy-use bilinguals doing?

Need to:

  • See what Nen speakers are doing. Are they decategorialising?
  • See what Nambo speakers are doing. Are they decategorialising?
  • See what the heavy-use bilinguals are going. Are they decategorialising?

Code for Nen:

  • Identify the focus markers (DEM+COP followed by ambifixing verb)
  • Note: Is it decategorialising? Y?N. If yes, on: Tense, Number, Person, All?
  • Mark in also instances where DEM+COP is functioning just as the copula (code = Z)

Tier Structure

NQN_SB.JPG

Pastor Blag interviewing his wife Sambo in Nen language, Bimadebn Village. 2014.

Tier structure:

  • Prom: Speaker initials and PM (e.g. BT PM)
    • Sph: Spelling (orthographic) Phon. Type whatever is in the transcription text.
    • ClPh: Close Phonetic. Paying attention to consonant voicing, and syllable boundaries where possible. Don’t worry too much about vowel quality at this point in time. (e.g. ge.ym, gym, ge.dn.z.ron)
    • PromGl: Prominence gloss. Break down of demonstrative type, and agreement of copula. (e.g. DEM1+3sgU:nphd. See below, “Types of DEM” and “Copula Code”)
  • WhichV: Where is the main verb? (e.g. R, RR. See below, “Which V”
  • Decat: Is the copula of the prominance marker decategorialising? Yes (D), No (A), others. See below, “Decat Tier Code”
    • Decatcat: Category that is decategorialised.
  • NP: What is the person number of the NP of the prominence construction?

Tier Codes

DSCN0454-2.jpg

Rusien (left) being interviewed by Fasawar (middle) and Jimmi (right), Bimadebn Village. 2014.

Types of DEM

  • DEM1 = ge
  • DEM2 = gs
  • PV = äte
  • FUT1 = bä
  • FUT2 = ä

Copula Code
Eg:

  • ym = 3sgU:nphd
  • tm = 3sgU:ypst
  • dnzron = 3sgU:rmpst
  • däron = 3duU:rmpst

WhichV

  • R – The first verb to the right (in the transcription) is the main verb.
  • RR -The second verb to the right (in the transcription) is the main verb.
  • Z – Zero copula.

Decat Tier Code:

  • D – Decategorialised
  • A – Agreeing
  • C – Caveat. There appears to be decategorialisation happening, but it may not be a true case due to contextual information (e.g. this bag gs ym, it was made like this back in the past). The Decatcat tier for code C is still to be coded as though a D.

Decatcat Tier Code:

  • N – Number
  • P – Person
  • T – Tense
  • When there is more than one, code in alphabetical order. (e.g. tense and number = NT, person and tense = PT)

pm

NP Tier Code:

  • Orthographic representation of the prominence construction NP.
  • NPDeets: person and number, e.g. 3sg

Examples in ELAN:

Screen Shot 2017-02-02 at 9.02.44 am.png

A regular example of where the prominence marker is agreeing with the NP person numer and the main verb TAM.

Screen Shot 2017-02-02 at 9.21.06 am.png

Note the Decat tier. Coded C for ‘caveat’, and Decatcat tier is coded T for tense. The prominence construction reads something like “This house gs ym had been burned.”

Notes on odd cases

  • When the PM or main verb has a super plural
    • Coded as D on the decat tier. The NP tier for the noun phrase sets the person and number as 3sg.

Also coding for gesture

NQN_BT.jpg

Pastor Blag mid-gesture.

Code on Gesture tier:

  • TO = Touch Object
  • FP = Full Point
  • HP = Half Point
  • FB = Full Beat
  • HB = Half Beat
  • OG = Other Gesture, e.g. motion, eye gaze, nod, without a point or beat. If these other gestures are accompanying a point or beat, it is coded for point or beat.
  • MOT = Motion gesture (e.g. acting out verb, motion of inclusion (e.g. ‘all of us’), motion of hither/thither)
  • NG = No Gesture

Where ‘Point’ includes open hand gesturing to a referent (real or imagined) as well as the canonical one-finger point.

Where ‘Beat’ = non-pointed hand motion approximating a up-down/down-up movement of the hand.

Where ‘Half’ means below the waist.

Fieldwork 2016

20160729.JPG

Flight out from Morehead Station, South-Fly District of Western Province, Papua New Guinea.

It’s been about a month since I’ve come back from fieldwork, and I’m also back from a bit of annual leave. Feeling refreshed and ready to get back into the fray of things!

Last year I left my fieldsite a month earlier at the onset of a harsh dry season, made worse by the worst El Niño event in a decade. The news once I’d gotten back to Australia wasn’t good, and also very difficult to get hold of news. I was unable to get hold of my contact in the village, and what I’d heard from the neighbouring village via whispers on the grape vine were about deaths. These villages are almost 100% subsistence farming. That means they have to grow all their food to live. Because of the drought, the usual wet season didn’t come this year. Which means that there’s a reduced harvest. Which means hunger.

20151018-10.JPG

Aftermath of a bushfire, October 2015.

Naturally there was a lot of trepidation about going to the field this year. I wasn’t sure until about a month or so before going that we would actually be going at all. On the one hand, you don’t want to be a burden to your host community. If the harvest is reduced, and feeding mouths is tough, an extra adult in the community is an extra mouth to feed. In a place where hospitality to visitors is so important, locals will insist on feeding you… which may mean that other needy people (e.g. kids) might not get as much. On the other hand, you don’t want the community to feel they have been abandoned and forgotten. The South Fly Region of Papua New Guinea is one of the least developed areas of Papua New Guinea, and the locals feel that their government, and the outside world, has forgotten them.

So my supervisor suggested a short (two week!) trip, and I went along. And it was a very, very good thing to do.

20160726.JPG

Sorry it’s out of focus… The tough people of Govav village.

Firstly, I was able to see for myself what the effect of the drought was on the area. It was a real relief to be able to see people safe and sound, and in pretty good spirits. I had heard that in other areas of PNG, social problems in communities were exacerbated due to resource scarcity caused by the drought, but I wasn’t able to detect that in the two weeks I was on the ground. Some people were a tad gaunter than last year, but there were no deaths across the three villages I work with. People seemed genuinely happy to see me. And I was very happy to see people doing ok.

The second good thing about the trip was that it put a few things about natural disasters like drought and famine into perspective. This drought was scary from a personal point of view, knowing how tough the terrain is, and what a very basic subsistence lifestyle means in terms of survival. This drought episode has reinforced to me the robustness of human beings. I don’t mean to trivialise the drought though; I can only imagine what it is like to have to live through the thought that you might realistically not be able to survive on your home turf because you can’t feed yourself and your family. It just makes the thought and news very real that global warming and extreme weather phenomena are threatening the lives of millions of people. My host village is about 1000 people, in an area 30km by 10km. People will suffer, but humans have a way of surviving through it as a species. When we talk about human resilience we tend to gloss over the suffering that is experienced through that though.

20160727.JPG

The awesome ladies of Arovwe and Bevdvn, looking over a recording I made last year and helping me out with translating it.

And the third good thing was, of course, I got some new data, and worked through a lot of data from last year too. I was thrilled to be able to work much more closely with the women in the community. The ground work and time spent last year has born fruit this year. I just felt good in the field, getting work done, getting along with people, our gear such as the solar panel and power all worked etc. I can see that, indeed, fieldwork at the same field site can get easier over time.

Now that the El Niño is over, the La Niña has taken over and is brining a lot of rain. It rained a lot while I was there. The last two weeks saw a lot of rain. Which may bring a new set of problems for the people in South Fly. Time to give them another phone call to see how they’re doing.

Quantitative Sociolinguistics = Labov?

IMG_1042.JPG

The Engma Room at the Centre of Excellence for the Dynamics of Language (CoEDL), Canberra Node.

A few months ago a few of us Wellspringers and CoEDL students at the Australian National University were having lunch, and talking about the topic of my last blog post: the overlaps and differences between sociolinguistics and variationism. I was somewhat glad to see that quite a few of us had conflated the two, or were still unsure about how the two are different (this was particularly the case if you didn’t deal with variationism in your research directly). I tried to throw in my two-cents about why we have this conflation of the two things, and mumbled something about Labov. So I think it’s time to tick off that “Write About Labov in relation to Sociolinguistics and Variationism” box on my to-do list.

William Labov

I struggled a little bit on how to start this section, because introductory textbooks to sociolinguistics all talk about, in-depth, the famous Martha’s Vineyard study by William Labov (1). (If you want a really quick and dirty overview, checkout here.) As for the man himself, Wikipedia already has a pretty good overview, so it’ll be a bit redundant for me to write out more again… Having said that, there’s no way around extrapolating on the Martha’s Vineyard study if we’re to understand how sociolinguistics and variationism get conflated. So even if you know the Martha’s Vineyard story, bear with me, I’ll try and make it worth your while.

Once upon a time, there was a concept called “free variation”. I think this term is still in use, still with the original meaning of “speakers freely alternate between various forms” (you definitely see it used in descriptive grammars). Along comes Bill Labov and shows, empirically, that there are sometimes social motivations for why speakers alternate between forms. Why do some speakers on Martha’s Vineyard pronounce their vowels one way, and others another way? That’s because those speakers who are more oriented towards main land American culture pronounce their vowels more main-landy, while those who are more island oriented tend to pronounce their vowels like the vernacular dialect.

20160120-Eldridges_map_of_Marthas_Vineyard_(4587187280)

Drawing on social motivations to explain variation was a break through at this time in modern linguistic history. But another thing that was revolutionary about Labov’s study was that it used quantitative and qualitative data collection and analysis.

These quantitative methods that Labov started, and were further developed by linguists such as David Sankoff, Gregory Guy, Shana Poplack etc etc did NOT necessarily look at the social dimensions of language. In fact, the Labovian method was used to study variation in a numeric and systematic way. So to simplify it:

  • Assumption of variation + Quantitative method part = variationism
  • Assumption of variation + social explanations + social dimensions of language = sociolinguistics

As I talked about in this post, sociolinguistics is a pretty broad term with a range of interests that cross-over with anthropological linguistics and linguistic anthropology. But “Labovian sociolinguistics” (which is what I meant in said post when I said “sociolinguistics”) has that emphasis on quantitative methods, which sets it apart from the other socio-culturally oriented linguistic things.

  1. People say the same thing in different ways.
  2. The theory was that there was free variation if the grammar couldn’t give an explanation for the variation.
  3. Labov said that was rubbish, and that social and cultural factors can explain variation.
  4. Labov used a method that sought patterns and correlations between who and when these variations occurred.
  5. Boom, variationism.
  6. The explanation of why variation occurred, was a social reason.
  7. Boom, sociolinguistics.

So this conflation of “sociolinguistics” and “variationism” makes sense historically, so to speak. It’s kind of an interesting case of how meaning drift can happen, if you aren’t paying attention to the particulars of how things develop, I guess.

Speaking of Labov…

It was a real privilege to hear a living legend.

Sociolinguistics and Variationism are not the same thing

Of courser I would lie, and my first meaningful post of 2016 is neither about PRAAT or micro variation, but about the definition/scope of sociolinguistics (again) and variationism. But I guess if I’m going to talk about microvariation, it’s kind of necessary to clear this ground about what is generally meant by variation and variationism in linguistics, and the close relationship it has with sociolinguistics (read: Labov. If you don’t know what Labov is, he’s a godfather of linguistics, and we’ll do a proper post about him later. I guess it’s kind of inevitable).

So what is the relationship between sociolinguistics and variationism? From the title you can tell that they are not the same thing. But their origins come from (essentially) the same place, so they can be confounded.

20150719_on canon-5.JPG

Me being confounded by the Nmbo language of Papua New Guinea. Ok, that’s a stretch, I know, but we need a picture to break up the text here, ok? 😛

In my last meaningful post I tried pulling apart the difference between Linguistic Anthropology, Anthropological Linguistics, and Sociolinguistics. One of the things that makes sociolinguistics stand out from other areas of linguistics is that it is interested in social meaning, but also in seeking patterns and correlates between how language is used by groups of people (and to varying extents, how language is used by individuals) (1).

When I started off in my PhD two years ago (argh!) I began by reading a book by Sali Tagliamonte titled Variationist Sociolinguistics: Change, Observation, Interpretation (2012). Since my topic is about studying “variation” within a population of speakers, this made sense. What I mean by variation is something like “how do people talk about the same thing in different ways”. A famous example often used in text books is the alternation between word final [n] or [ŋ] in English speakers: for example pronouncing a word laughin’ for the first case, laughing for the second case. (2) Is there a reason why some people, sometimes, pronounce words with the  [n], not the “proper” [ŋ]? Studying this kind of alternation in speech is what “studying variation” means.

So why do some people say the same thing differently? The big break through in the twentieth century for the science of language was that these differences are in part due to where the speaker is from, their background, identity and other ‘social things’ (what in the field is called “socially conditioned variation”). The [ŋ] vs [n] is a well-known dialect difference in England, which is also sensitive to speech style (e.g. polite and careful vs. rapid and casual) (see Trudgill 1974).

20160120-FullSizeRender.jpg

The copy of Sali Tagliamonte’s Variationist Sociolinguistics that’s prettily sitting on my desk’s perpetual book pile.

I loved reading Tagliamonte’s textbook. I had taken a subject in my undergraduate level degree called Introduction to Sociolinguistics or something like that, so I was vaguely familiar with the things Tagliamonte was talking about.. but not in this kind of depth. But it took me a while after reading this text book’s methods section, and reading papers such as the one provided by a member of my supervisory panel, that variationism and sociolinguistics are not the same thing. I had, somehow, conflated variationism as a theory and method with frameworks and approaches inherent in sociolinguistics. There is plenty of overlap, but actually, this is another one of those things where the origins and history of sociolinguistics as a field have (probably) helped conflate the two things.

Let’s articulate this here:

  • Variationism: Research into what patterns and correlations can be found in regards to how people vary their speech.
  • Sociolinguistics: Research into the social meaning of language use, with an emphasis on seeking patterns and correlations from a largish data sample.

Tagliamonte’s book is titled Variationist Sociolinguistics. That is, she is talking about sociolinguistic research that uses the variationist framework and method. But variation doesn’t have to be socially conditioned. In fact, it’s very often conditioned by the grammar of a language. Going back to that [ŋ] vs [n] difference from before, it turns out that there are grammatical reasons why people vary their pronunciation between [ŋ] vs [n]. According to  Houston (1985) nouns are much more likely to be pronounced with the [ŋ] rather than [n], while verbs are more likely to be pronounced with [n].

So.

This conflation was a real n00b mistake, I’m aware. Somehow I had thought that variationism and sociolinguistics were the same thing because, you know, Labov.

I think my next post is going to have to be about William Labov, and how much his work has shaped the field of sociolinguistics, both theoretically, but also methodologically. There are plenty of things out there that talk about his theoretical contributions to linguistics, but I find that very few have explicitly highlighted his methodological contribution (probably because it’s so self evident). This is the second post I’ve had to shove aside the history of sociolinguistics and Labov, so I guess we’ll cross that bridge next post.

(1) Walker and Meyerhoff (2014) have recently writtenabout how it may be that the variable of “individual” is very often the most important factor in explaining the pattern of variation found within speech. That is, a person’s personal language history and their individual quirks are able to best explain patterns of variation found in their speech, rather than things like class, ethnicity, etc., especially when looking at small language’s communities.
