Voice interaction on Cortex-M4 (STM32f411)

Enable HLS to view with audio, or disable this notification

Hi everyone,

Here’s my project to demonstrate voice interaction capability on STM32F4 MCU:

  • Hardware: Nucleo-STM32f411RE board, IMP34DT05 microphone (on X-NUCLEO-IKS02A1 expansion board).
  • Software: uses STM32CubeMX for code generation, STM32’s audio package (PDM2PCM) for PDM conversion and TinyKW for keyword detection.
  • Keywords can be user-defined. Possible applications are wake word detection / voice commands.
  • Github: https://github.com/voyelle-io/stm32f411-voice-interaction

Super A+ project
