1. Voice Chip
The speech chip actually converts speech signals into numbers through sampling, and then stores them in the ROM of the IC. The circuit will restore these numbers into speech signals. Simply put, after recording, the recorded voice is burned into the chip and then played through the speaker.
2. Sound Module
The voice module is actually a type of module that combines recording and playback functions. In home appliances, telephone, conference and other recording systems, as well as in monitoring devices or high-end toys, there are also some teaching devices that have voice modules.
3. Summary
There is generally no difference between voice chips and voice modules, but they are different in application and design. The voice module is a semi-finished product with voice playback function, and if it is to be applied, secondary development must be carried out. The voice chip can be used directly, and the cost is relatively low.
