Time-Expanded Speech to Improve the Intelligibility of Consonants for the Hard-of-Hearing

Our investigations addressed the efficacy of temporal processing to the clear speech advantage. A case for synthetic clear speech in the context of hearing impairment was constituted. Stop –vowels of English language were used as test stimuli; were subjected to non-uniform time-expansion. Burst duration, Voice onset time, and Formant transition durations segments were selectively time-expanded by 50% / 100% of their original duration. Hearing impairment was simulated at three SNR levels. The perceptual analysis was accomplished in terms of Information transmission analysis measure and statistical measures. Burst duration expansion by 50% reported to be beneficial at lower SNR level; while VOT and FTD lengthening did not contribute to improved intelligibility.
