Voice Recorder IC (Chip)
In terms of functions, voice chips can basically be divided into recording voice chips and playback voice chips. When designing a product that uses a recording solution, you must first consider whether to record live speech. If you need to record speech, choose a voice chip with a recording function. Otherwise, choose a voice chip with only a playback function. Usually voice chips with recording functions have the function of playing back speech. However, when playing speech, the sound quality is not as good as that of specialized playback speech chips. Therefore, when choosing a speech chip, you must weigh factors such as function and sound quality.

Product Description
The voice recorder chip makes execellent GPS systems, central locks for cars, anti-theft alarms and parking sensors. It can also be used in microwave ovens, cookers, toll stations, lifts, senior toys, etc. With an operating voltage of DC2.4 ~ 5V and DAC and PWM audio output, this chip supports voice lengths of about 40 seconds at a 6KHZ sampling rate. In addition, it supports audio file playback with several sampling rates.
Product Details
For the recording solution, the user can choose a recording IC chip or a recording module. The recording and playback IC and the recording module can record and save at will by triggering the REC recording button, and after the recording is completed, trigger the PLAY play button to play the recording, and can realize repeated recording and playback. A voice storage chip (see the schematic diagram in Principles of Recording Chips), which includes two processes, ADC and DAC, both of which are completed by the chip itself, including steps such as voice data collection, analysis, compression, storage, and playback.
