Vesper grabs $15M to build a durable low-power mic that listens forever



As digital assistants like Siri and Alexa become more intelligent, there’s a growing need for them to always be accessible.

Current microphone tech has been too power-hungry to keep permanently enabled. As a result, a new class of products, home assistants, like Amazon’s Alexa-enabled products and Google Home, have arisen as power-connected alternatives.

Vesper is aiming to keep mobile devices more tuned into their surroundings through the startup’s VM1010 piezoelectric MEMS microphones which generate electric energy from the very sound waves the devices receive.
