Qualcomm® Smart Headset Reference Design for Amazon AVS

This is the first available end-to-end Bluetooth Qualcomm® smart headset reference design which supports push-button activation for Alexa for an Android phone that has the Alexa app installed. This reference design can be used by manufacturers to help them evaluate Alexa on-the-go with a mobile phone. It is based on the Qualcomm® smart headset platform. Based on Qualcomm Technologies’ Bluetooth audio SoC QCC5124, the solution combines ultra-low-power consumption to help extend playback time and battery life. Qualcomm cVc™ noise reduction technology supports active noise cancellation and superior audio quality while in a voice call. Manufacturers can add Qualcomm aptX™ HD designed for high-resolution wireless audio.

Following evaluation via this reference design, manufacturers can then step up to the full development environment with a comprehensive suite of software and tools to customize or develop their own headset products.

This is the first available end-to-end Bluetooth Qualcomm smart audio headset development kit which supports push-button activation for Alexa for an Android phone that has the Alexa app installed. It is designed to provide the hardware and software components needed to help manufacturers overcome common and significant design challenges for small form-factor, low-power smart headsets and to commercialize their own products quickly and more cost-effectively.

The Qualcomm® smart headset development kit for Amazon AVS is the first to support mobile accessory kit (AMA), a protocol that runs over Bluetooth that enables users to easily connect their Bluetooth-enabled audio devices with Alexa, using the Alexa Mobile App (AMA) on Android or iOS devices. This means device makers no longer need to integrate with AVS or to add any communication hardware beyond Bluetooth, which reduces cost and accelerates time to market. At a high level, AMA enables AVS to send speech from the accessory to the Alexa service and a control service for exchanging control messages between the accessory and the Alexa Mobile app. Bespoke development of the Smart Headset Reference Design is possible with the following Bluetooth Developer License. For more detailed hardware development the open board development kit can be purchased along with a Transaction Bridge for debugging.
