Application of DSP speech synthesis system on service robots

The main purpose of this paper is to perform the voice signal processing and synthesis to apply to service robots using DSP TMS320C6713. In this study, we select the C language program written with DSP; the voice signal is restored to play. The speech synthesis is implemented using linear predictive coding (LPC) approach in the paper. Because the LPC synthesis is a coding technique of time waveform, one can reduce the transmission rate of signal in time domain; save perfect voice messages. It can be obtained a very high naturalness and clarity for the synthesis of a group of words. We scored the synthesis results by subjective listening test ways.
