InTraSAL

First proposed for Bangladeshi Bengali (as B-ToBI) in Sameer ud Dowla Khan's 2008 dissertation and later expanded to cover several diverse languages of South Asia, the Intonational Transcription of South Asian Languages (InTraSAL) is a phonological model and annotation system for the intonation of a range of South Asian languages that share several prosodic characteristics.

The model is part of a tradition of prosodic research known as the Autosegmental-Metrical (AM) Model of Intonational Phonology, which has produced intonational models of a wide diversity of languages. Many of these models have in their name, based on the prosodic annotation system they use.

The most recent publication describing the B-ToBI model is a 2014 chapter of Sun-Ah Jun's , and the most recent description of the larger InTraSAL model comes from a talk at SALA-34. This website will be updated as the model continues to grow and evolve. This version was last updated on 17 April 2019.

Introduction

InTraSAL is the name for both a phonological model of the intonation of South Asian languages and the annotation system used to represent analyzed recordings of speech in these languages. This website attempts to describe both the model and the annotation system simultaneously. Each tonal element is illustrated in an example sound file along with an image of its pitch contour in blue. Below the pitch contour are three transcription tiers:

  • The tones tier shows the tonal events, e.g. L*, Ha
  • The words tier shows segmentation and transcription of the text, e.g. ca, ḍhallo/Dhallo
  • The English tier shows English labels for words and suffixes, e.g. 'tea', 'spill-PST-3'

Below the image of the pitch contour and tiers, a link to the sound file is found on the [recording code], along with a repetition of the words tier transcription and a 'loose English translation' of the utterance.

About the recordings

InTraSAL is based primarily off of extending the B-ToBI model of Bangladeshi Bengali to other prosodically similar languages of South Asia. For the time being, the current webpage includes only sound files from Bengali, and will include examples of other South Asian languages in future updates.

The recordings included here were all produced by native speakers of Bengali who grew up in Bangladesh (or in a few cases, in India) and later moved to the US or were visiting the US at the time of recording. Recordings were made in the participants' homes in Southern California, between 2006-2007. Most recordings here were made from a prepared script, designed to minimize the appearance of obstruents (which interrupt the tracking of pitch). Recordings with an "S" ("spontaneous") in the middle of the identification code were unscripted; these were collected from speakers "reading" from , an illustrated children's book with no text.

While the B-ToBI model is primarily based on Bangladeshi Standard Bengali (as spoken by Bangladeshi Americans), it can reasonably be extended to Indian Standard Bengali and nonstandard regional varieties of Bengali. (With adjustments to allow for lexical pitch accent contrasts, it could presumably be extended to , Chittagonian, Chakma, Arkani/Rohingya, etc.) Indeed, some participants used their native regional varieties in the unscripted recordings, and these are incorporated into the B-ToBI model.

 

Publications

InTraSAL is a model in progress, and no published descriptions currently exist. One proceedings paper and two plenary presentations can serve as an initial description, and are included below:

The B-ToBI model for describing Bengali intonation is better described in the published literature, with selected publications listed below:

  • Khan, SD (2014). . In Sun-Ah Jun (ed.). Prosodic Typology II: the Phonology of Intonation and Phrasing. OUP. ()
  • Yu, Kristine M., SD Khan, and Megha Sundara (2014). . Proceedings of Speech Prosody 7. Dublin: Trinity College.

Researchers

InTraSAL and B-ToBI build on the work of many linguists around the world, many of whom work in different frameworks. I've included links to just a handful of researchers (in alphabetical order) who study Bengali intonation, some of whom work directly with B-ToBI and some of whom work(ed) on previous models or alternative models of Bengali intonation:

  • (U Delhi): proposes an information-structural model of Bengali intonation in 2008
  • (USC): specializes in focus prosody in both Bengali and Hindi
  • (Tripura U): 2001 dissertation describes Tripuri and Kolkata Bengali stress assignment
  • Jennifer Fitpatrick-Cole (U Konstanz): co-authored a 1999 paper on emphatic particles with Aditi Lahiri
  • (UCLA): co-authored "" in 1991 with Lahiri
  • (USC): uses B-ToBI to investigate the prosodic factors in complementizer order variation
  • Sameer ud Dowla Khan (Reed): developed the B-ToBI model and is co-authoring a description of infant-directed intonation with Yu and Sundara
  • (Oxford): co-authored "" in 1991 with Hayes and a 1999 paper on emphatic particles with Fitzpatrick-Cole
  • (U Mass Amherst): proposes a prosodic model in 2006 with data from Hayes & Lahiri
  • (UCLA): currently co-authoring a B-ToBI description of infant-directed intonation with Yu and Khan
  • (ZAS Berlin): 2002 paper provides an OT syntactic account of phrasing with data from Hayes & Lahiri
  • (Yale): currently using B-ToBI to investigate the focus realization of NPIs and related phenomena in Bengali
  • (U Mass Amherst): currently co-authoring a B-ToBI description of infant-directed intonation with Khan and Sundara
