Block Diagrams Software Videos Resources Forum

Adding wake word detection to your embedded application is a walk in the park with EOS S3. Pre-qualified for Alexa wake word or any custom wake word and voice commands

In consumer products, voice recognition alone is not enough; the best user experience comes only when you fuse voice with other sensors. QuickLogic enables this through our multi-core chipset and broad range of best-in-class audio front end & wake word software.

Benefits

Longer battery life without sacrificing user experience
Familiar Arm Cortex®-M4F toolchain enables fast time to port your software to EOS S3 platform
Supports concurrent sensor processing with voice recognition

Features

Hardware-optimized low power sound detection
Supports 1 and 2 microphone use cases
Low voltage option for 33% power reduction
Integrated Arm Cortex®-M4F with open SDK and toolchain
