Overview

The TIDEP0066 reference design highlights the voice recognition capabilities of the C5535 and C5545 DSP devices using the TI embedded speech recognition (TIesr) library and instructs how to run a voice triggering example that prints a pre-programmed keyword on the C5535eZdsp OLED screen, based on a successful keyword capture.  This design also describes the steps to customize the trigger phrase.

Features
  • Efficient active power for always listening applications
  • Small footprint (down to 7mmx7mm) with optimized pinout
  • Based on open source library
  • Enables addition of voice control to any application
