TEXT SPEECH
GENERAL DESCRIPTION SPDS104A-01A text-to-speech synthesizer that contains three types speech synthesis mode associated with word mode, syllable mode diphone mode. SPDS104A-01A based model SACM_S480 PSOLA that able synthesize arbitrary English word. Users easily high quality speech sound from transmitting compressed data prosody parameters SPDS104A-01A. SPDS104A-01A communicates with master microprocessor using five control lines MA[1:0]) eight data bus(AD[7:0]). Word syllable encoded data stored master microprocessor. master microprocessor SPDS104A-01A constitute long duration audio application transmitting decoding large compressed data. sleep mode, SPDS104A-01A lower power consumption.
