Abstract :
The authors study the problem of coding spectral information in speech at bit rates in the range of 100-400 b/s using speaker-independent phone-based recognition. Spectral information is coded as a sequence of phonetic events and a sequence of transitions through the corresponding hidden Markov model (HMM)-based phone models. This simple phonetic speech-coding system has been shown to be a promising approach. A simple inventory of phonemes is sufficient for capturing the bulk of the acoustic information
