The SPCE061A A/D switch has 8 channels, including 1 channel is the MICIN input, it specially uses in to the pronunciation signal carries on the sampling. . The pronunciation signal transforms the electrical signal after Mic, by separates the straight electric capacity to separate the direct ponent, then input to SPCE061A interior preamplifier. SPCE061A interior automatic gain control electric circuit AGC can track the tonic train signalling level as necessary which, the surveillance preamplifier outputs, when the input signal increases, the AGC electric circuit automatically reduces the amplifier the gain。 When the input signal reduces, the AGC electric circuit automatically increases the amplifier the gain, in order to causes to enter A/D the signal to maintain at the best level, also may cause to reduce to slightly. The A/D switch enters the front part of a jacket kHz sampling to the input tonic train signalling, and defers to will insult the positive audio frequency code form to carry on the code, each second will take 16kBits the memory space. The system expanded a capacity is 1Mbits SRAM memory HM628128A saves the pronunciation data . When playback, saves HM628128A in the pronunciation data order to take out, after the decoding, carries on the D/A transformation output by the 8kHz speed, after the electric capacity filter, restores the primitive pronunciation profile, through actuates the speaker to put. ACMDVR has the sound recording and the playback function, and uses SACM_A2000 the algorithm, when the sound recording picks .the 6K material rate and the 8K sampling rate gain pronunciation resources, after passes through the SACM_A2000 pression to save in expansion SRAM 628128A, records Man Yinhou automatically to start the playback. In recording outside period from the ADC channel gain sound recording material, also carries on it after the SACM_A2000 form the code to store meets in SRAM。 But in broadcast period gains the pronunciation material from SRAM, carries on the decoding to it, then waits for the severance service subroutine to send out it the DAC channel to record the playback to arrange the decoding is depends on the transfer storehouse function to plete, does not need us to design the hardware electric circuit. Insulted the positive pany to provide the rich storehouse function, we so long as the understanding storehouse function use, could with ease plete pronunciation recording and sending out.With the rapid development of electronic technology, speech processing technology is more and more in industry, transportation, munication and applications. Speech processing theory and technology has bee more perfect and mature. The speech technology needs more urgent, the voice processing practical product appears ceaselessly.Voice recording and playback device in the life of people in different kinds of entertainment has been to provide various services for the people. For example, the repeater for learning a foreign language provides a convenient, it is not only a
