Abstract

A new version of the Visual Speech Articulation Training Aid was implemented which provides real-time visual feedback for speech articulation training. This version was migrated to a Windows Multimedia PC from a previous version which used a Personal Computer (PC) system and additional specialized and expensive custom hardware. This new version will make the system more available to schools and private users. A new method was developed for computing spectral/temporal features which characterize the speech sounds. In addition to the typical frame-based spectral analysis parameters, the new method represents temporal changes of the spectrum with a small number of features. The flexible method implemented can easily be adapted to compute features for a wide range of speech processing tasks. Linguistically-based distinctive features were also investigated as candidate features for the visual display system. Some experimental results are given for vowels using the new system.
