Abstract

The invention discloses a voice storage and playback system, belongs to the technical field of automatic control and relates to an intelligent control platform system. The voice storage and playback system is characterized by comprising a single-chip microcomputer (1), a power supply circuit module (2), a keyboard setting module (3), a memory module (4), a D / A conversion circuit module (5), a rear-mounted band-pass filter module (6), an A / D conversion circuit module (7), a data display module (8), a gain amplifier module (9), a preposed band-pass filter module (10), an output amplifier (11), an earphone module (12) and a sound pick-up (13). Compared with the prior art, the voice storage and playback system has the advantages of being high in intelligence, long in recording time, wide in application occasions, good in sound quality and the like.

Description

technical field [0001] The invention belongs to the technical field of automatic control, more specifically, it belongs to a voice storage and playback system. Background technique [0002] In terms of the current research status of speech technology, the technology has made great progress. Speech recognition and speech synthesis technologies are two key technologies necessary to realize man-machine voice communication and establish a spoken language system capable of listening and speaking. Make computers have the ability to speak and understand people like people. [0003] Speech recognition technology mainly includes several aspects: voice control, electronic voice, continuous speech recognition, discontinuous speech recognition and speech learning. At present, there are some obstacles in the support of Chinese and English, and the realization of mixed Chinese and English recognition. At the same time, it is difficult to be accurate in recognizing a large number of wor...
