Microsemi AcuEdge™ Development Kit for Amazon AVS

The success of personal assistants that you interact with via the spoken word, such as Amazon’s Alexa, Apple’s Siri, and Google Home, has made voice control a hot-ticket item in system design. Getting started in this technology, though, has required significant audio and signal processing expertise to address issues in background noise and the speaker’s location. A new development kit from Microsemi, in partnership with Amazon’s Alexa voice service (AVS), seeks to simplify startup so developers can focus on application rather than implementation.

Engineered to help you evaluate voice-enabled front-end audio systems for your Alexa-enabled products. This development kit features Microsemi’s ZL38063 voice processor powered by the company’s proprietary AcuEdge™ technology for front-end audio clean-up and preloaded “Alexa” wake-word detection. The kit includes a two microphone configuration that has been tested for both 180° and 360° pick-up.
