Add TMPpcm-master.zip to Arduino Library

  • Sketch >> Include Library >> Add zip Library

Step 5: Change Mp3 to Wav Files

Use

Step 6: Arduino Mega

Connect Smakn Speak Recognition Module(SRM) to Arduino MEGA

  • Connect SRM GND to GND on breadboard.
  • Connect SRM VCC to 5V on breadboard.
  • Connect SRM TX to Pin 10
  • Connect SRM RX to Pin 11

Upload VoiceRecognitionV3-master.zip to Arduino Library

  • Click on then Sketch >> Include Library >> Add zip Library

Code:

  • Train up to 80 words using sigtrain. eg(sigtrain 0 BrunoMars)
  • It will train Bruno Mars to position 0 and can be used using load 0.
  • While in load when it hears Bruno Mars it will output it in the Serial Monitor.
  • You load 7 commands at a time and see how many are in and what values are in load using vr.
  • You can clear the load by using clear.
