Speech Recognition Reference Design on the C5535 eZdsp™
TIDEP0066
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
Personal electronics
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
