Shenzhen, China — Horn Audio, a global manufacturer of audio products, today announced that it has developed a new white-box bluetooth headset that allows hands-free interaction with Alexa. The Horn Luduan V4 is the first product to be certified by Amazon on the Alexa Mobile Accessory (AMA) protocol, and offers high-quality wake word detection with ultra-low power consumption. (It provides 15 hours play time from a 340 mAh battery!)
The always-on microphone processing is performed by DSP Concepts' TalkTo™ Audio Front End (AFE), powered by Audio Weaver®. In addition to microphone beamforming, the Low Power variant of TalkTo features environment-aware noise suppression, which uses the minimum processing-power possible for a given acoustic environment.
