Vesper Receives Alexa Voice Service Certification for ZeroPower Listening Extended Battery Solution


Vesper, a developer of acoustic sensors, has seen its ZeroPower Listening (ZPL) technology certified by Amazon for extended battery and far-field voice interactions. Vesper's piezoelectric MEMS microphones are powering the first hands-free, extended battery life Alexa-enabled headset that uses ZPL technology.

The headset, LuduanV4, is a two-mic Bluetooth neckband headset with Alexa built in, allowing users to interact and access thousands of Alexa skills, such as music playback and smart home controls. The headset, which is based on Ambiq's Apollo3 Blue Wireless SoC, incorporates Vesper's VM1010, a piezoelectric MEMS microphone with ZPL technology, which allows systems to be in deep hibernation mode until awoken by a wake word, thereby greatly extending battery life.

ZeroPower Listening eliminates the button in push-to-talk devices. Vesper's VM1010 brings voice activation to battery-powered devices of all kinds.

"Over the last year, we've collaborated with the Alexa Voice Service team at Amazon to develop this major advancement in low power to bring far-field Alexa capabilities to battery-powered devices," said Matt Crowley, CEO of Vesper, in a statement. "This is the first Alexa-powered headset to feature ZeroPower Listening, which will greatly extend battery life and voice interface for consumers."
