We have Voice Recognition module V2 and it supports 15 commands in all and only 5 commands at the same time. On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could be imported into Recognizer. It means only 5 voice commands are effective at the same time.

On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.

  1. Soumen

    module is good for Arduino but not for Raspberrypi


  2. Dheeraj (verified owner)

    Great product, has an appreciable range. The mic is generic but manages well with considerable noise too. Totally worth the price. Only request is to include some documentation or resources on how to use it as there isn’t much available. Excellent product.
