ProductIntroduction

The Speech Recognition Module is an AI offline speech recognition product. It can convert speech into text or commands. First, it needs to record our speech with a microphone, and then the recorded speech will be processed into a series of special digital signals.

In the Speech Recognition Module, we have pre-recorded instructions, and the corresponding data are shown in the following table:

Instructions	Output Data

It should be noted that the accuracy of speech recognition can be affected by many factors, such as the speaker’s accent, speech rate and surrounding noise, etc. It is recommended to use it in a quiet environment.
