VowelQuest

 

The speech synthesis tool VowelQuest is a piece of software for phonetic/phonological research into vowel systems.

VowelQuest allows the user to pinpoint vowels in the acoustic space, by identifying what constitutes aurally the best fit to each of the vowels in their language. The tool provides as output the list of formant frequencies that correspond to these perceptually identified vowels.

The user 'gropes around' by clicking in the F1-F2 plane, and hears the corresponding sound. The third formant, F3, is modified independently. In order to facilitate the search in the F1-F2 acoustic plane, the user is able to visualize both the latest point that they clicked (current values, corresponding to the sound that is played) and the previous point, so as to be able to track the difference between successive choices.

This software is based on program of Pr. René Carré's , named "Search for the Best Vowel", written in Borland C Builder for specific experiments in speech production research. The program was written anew in the Visual C language, with René Carré's permission. New features have been added to make the tool more readily usable by novice users.

Highlights:

  • A tool to become familiar with formant synthesis
    Synthesizing speech from formant values is a good way to approach the Acoustic Theory of Speech Production (Fant 1960), which is the backbone of modern approaches to acoustic phonetics (e.g. Stevens 1998).
  • Friendly interface
    The present tool retains the advanced functions of R. Carré's original script. But the interface was devised so that the tool can be used by students without a prior command of phonetics software. Beginners should find it easy to get started and use this software for perceptual tests.
  • Unicode encoding for vowel symbols
    to ensure correct display of International Phonetic Alphabet symbols, as well as of orthographic representations in any of the world's writing systems.
  • Manipulation of three formants
    In many vowel systems, the third formant is an important dimension of the acoustic definition of vowels. For example, the contrast between /i/ and /y/ is typically a matter of F3 target, and rho-tic vowels (as in American English bird or Mandarin -er ?) are characterized by an especially low F3, sometimes below 2,000 Hz.

VowelQuest was developed at Speech Communication department, International Research Institute about Multimedia Informations, Communication and Application (MICA) in the framework of APRIL project funded by CNRS (2013-2014 PEPS programme)
