Abstract

This paper describes a low-cost, portable real-time DSP-based speech controller system to provide radio interface control command applications for the blind. The system recognizes spoken Mandarin Chinese words on a DSP chip (TMS 320C31) using a hidden Markov model. The function of the radio set, which includes a tuner, tape, and compact disk, were evaluated under both noisy and noiseless environments. Four subjects took part in the experiment and achieved 83% and 90% mean recognition rates under noisy and noiseless conditions, respectively. In addition, because this system is based on a DSP chip, it can easily be programmed to execute speaker-independent algorithms.
