Sugar ASR Voice Recognition Module

../../_images/asr.png

This is a Voice Recognition Module built for STEM education needs.

The module has an integrated microphone and speaker, creating an all-in-one voice recognition module. The module also has integrated LED, 3Pin Port, Servo Port and Motor Port, they can be controlled with the plug and play function of this module, meaning this module can be used as a standalone device without any programming.

Combining with Futureboard or Micro:bit coding, more voice commands can be used, unlocking the full functionality of the module including simple TTS functions.

The module is protected by a hard plastic casing to improve aesthetics as well as compatibility with plastic building bricks, allowing the module to be easily integrated into various use cases.

Sample Program

Program Instructions:

Say Lamp On or Lamp Off, the LEDs on the Micro:bit will light up correspondingly.

Press A or B to make the module speak the corresponding text.

  Note: Adding a pause between TTS commands will prevent the speech overlapping.
