Experiments in variable frame rate analysis for speech recognition
K.M. Ponting, S. M. Peeling · STIN · 1989
Abstract : The application of a simple variable frame rate analysis to the RSRE Airborne Reconnaissance Mission system, a continuous speech recognition system based on phone-level hidden Markov models, is described. Results are presented which show that, using standard three state models, the addition of the variable frame rate analysis results in considerably improved performance, which is close to that obtained using simple duration sensitive models.
