Computer-based visual speech training aids are potentially useful feedback tools for hearing impaired people. In this paper, a training aid for the articulation of short Consonant-Vowel-Consonant (CVC) words is presented using an integrated real-time display of phonetic content and loudness. Although not yet extensively tested with hearing-impaired listeners, real-time signal processing has been developed, flow-mode displays have been developed, and accuracy tests have been completed with a large database of CVC short words. A combination of Hidden Markov Models and time-delay neural networks are used as the primary method for the acoustic-phonetic transformations used in the display.
