True Wireless Stereo (TWS)

The market loves True Wireless Stereo (TWS) products. It's great to be able to listen to music and watch video wherever you are, but why stop there?
Why not add Internet-enabled voice assistants, or even health care features to your favorite portable audio devices?
The demand for multi-functional TWS products requires an ever-shrinking form factor and ever-decreasing power consumption for longer battery life.
This content introduces our solution for TWS.

Voice Detection

Seamless control with ultra-low power consumption

The Acoustic Activity Analyzer (AAA) uses AKM's unique analog analysis technology to enable always-on voice detection for only a few microamps. The AAA listens selectively for the human voice while rejecting all other audio activity and will only wake the system SoC once voice activity has been identified.

AKM's voice detection products record qualified audio activity to an internal buffer, which the SoC can access when it's finished booting. By doing so, no relevant audio activity is lost during SoC boot.
