Workshop on ‘Speech Sciences’

LDC-IL Workshop On Speech Science:

The LDC-IL Workshop in Speech Sciences was an advanced training course in phonetics/acoustics. It was held from March 10 to 21, 2008 . Most of the participants of the workshop had basic knowledge of phonetics. The first week of the workshop was meant for lectures and demos whereas in the 2nd week participants were involved in practical activities such as data recording, sound perception, transcription, reading of spectrogram etc. The workshop began with the introductory lecture on phonetics in which the main components of phonetics, such as articulation, air-stream mechanism, phonation and ori-nasal process were discussed in detail. However, the main emphasis of the workshop was on acoustics. Prof. Peri Bhaskar Rao who was specially invited for the workshop, discussed the following topics in detail: 

  1. General introduction to Acoustics--- it included description of sinusoidal and complex waves; analog vs. digital signal; frequency; fundamental frequency;  amplitude; formants, formant  transition, VOT, and source and filter theory.  
  1. Recording techniques  
  1.  Sound segmentation and introduction to speech synthesis  
  1. Acoustic characteristics of various sounds  
  1. Acoustic cues to various types of phonations  
  1. voiceless resonants  
  1. Analysis of tones  

The participants were exposed to the software such as Multi speech, wave surfer, PRAAT, Real time spectrograph, video phonetics and Real time pitch, used for speech analysis. 

During the second week the participants were involved in practical activities. They were asked to provide relevant data from their respective mother tongues; they had several sessions for sound perception, description and transcription. They were also involved in spectrogram reading so that they could differentiate between various consonants and vowels by using acoustic cues.
