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.
- 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
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
