VSR-02 embedded speech/speaker recognition module
1.  Product description:
VSR-02 embedded speech/speaker recognition module is designed for a wide variety of applications with speech/speaker recognition function. The training mode allows add speech commands/passwords to user-defined vocabulary. After the training when you speak to this module a word that has been trained, this module will take a defined action associated with the spoken. Equipping with this module allows control a device, appliance or toy just by speech. The module uses the advanced technique for electronic design and recognition algorithms, so that has high accuracy, short latency and good noise-robust performance.
