Looking for ELAN (and potentially CLAN) training

Posted by slpscientist at 2010-10-13 18:51  

I'm a postdoctoral rsearch in communicative disorders/human development. I'm beginning to code mother-child interactions for mother and child gesture and spoken language use. Many of these interactions have already been transcribed in SALT, although not coded for gesture. For gesture, I'm coding for type (diectic/conventional/iconic) and meaning (typically glossed as one word). I'm also coding utterances as being speech only, gesture only, or gesture and speech, and, if they are gesture and speech, whether the gesture is Reinforcing/Disambiguating/Supplementary. I'm also coding how mother respond to children's gestures, which is typically with speech, but speech that is non-contingent, contingent, or translated into a single or multi-word utterance.

So, given all that, I need a coding system that allows for coding of speech and gesture at multiple levels for two talkers. I'm struggling to decide on what software to use for coding.
-Noldus Observer XT is expensive and may not work well for language transcription, although I have used it in the past for coding prelinguistic communication.
-ELAN isn't compatible with SALT, but is compatible with CLAN, so potentially I could move SALT to CLAN to ELAN?? Also, I'm not sure about using ELAN for the types of speech coding we do. I'm having a hard time getting a picture of what ELAN can do and how to do it from reading manuals.
-CLAN is not very user friendly, in my opinion. I don't think it allows for viewing two videos (video angles) at one time (which isn't important for my current project, but will be in the future). I'm also not sure how well it can be used for coding gesture. However, the CHILDES database is a bonus of using CLAN, especially because we'd eventually like to share our videos and transcripts with the research community.

I don't want to spend weeks learning ELAN and/or CLAN only to find out these systems can't give me what I need. What I'm looking for is someone in the US with experience with both sytems(I'm located in Nebraska, but can easily travel). This doesn't need to be a primary researcher - potentially a graduate research assistant might know both systems. I have some research funding that might allow me to go for a day or two of training and/or watching someone else do coding in a lab. Even just a couple hours with someone who knows both systems would be incredibly beneficial, especially if they know anything about developmental research. On the other hand, if I need to, I could travel to someone who knows about ELAN and do my learning about CLAN in a seperate lab. It's even possible that we have money in our research budget to fly someone here who could do a training for several staff.

Does anyone on this board, or do any of you know of someone who uses CLAN and ELAN, especially developmentally? Someone open to doing a two-hour demo or having someone visit their lab for a couple days? Someone interseted in presenting on the options these two programs provide researchers?

Thanks!

Hi Sophie, most tools can be sorted into two categories: Video and multimedia annotation tools on one hand and audio transcription tools on the other hand. I would group CLAN in the latter, even though it shows movies, as I do not have the impression that it is actually comfortable to use it for multimedia annotation. Examples of the former group would be ELAN, Anvil and Exmaralda. I do not know which format SALT uses but you write that you can convert the SALT files to CLAN / CHILDES / CHAT, hopefully without loss of details? ELAN can import that, among a number of other formats such as Shoebox, Toolbox, Flex, Transcriber, Praat Textgrid, CSV or tab delimited... Anvil is somewhat limited with import / export functionality and video codec support, leaving only ELAN and Exmaralda as obvious candidates for free multimedia annotation tools. Both work on Windows, Mac and Linux and support multiple video formats. With ELAN, you can annotate videos with free text and items from controlled vocabularies. The annotations can be arranged in a hierarchy of tiers, which can be optionally time-linked to each other. You can also import timeseries / curves of e.g. measurement values, show them along with your annotations and do some basic processing such as calculating derivative curves. ELAN supports a variety of methods to navigate easily and with high precision through your video and annotations. Of course you can also annotate audio files. If you have enough screen space, you can annotate several videos in parallel.
