Vesper Launches 2nd Generation Smart Piezoelectric Voice Accelerometer with ZeroPower Sensing

Vesper continues to redefine its range of MEMS solutions for voice applications with the launch of the VA1210, Vesper’s 2nd generation analog piezoelectric smart voice accelerometer. The VA1210 offers higher sensitivity (+17 dB) and higher (+6 dB) SNR than the 1st generation VA1200 in voice pickup. Additionally, new intelligent features of Wake-on-Voice (WoV) and hardware voice activity detection (HVAD), introduced into the VA1210, enable a drastic improvement of voice quality True Wireless Stereo (TWS) earbuds.

Knowles announced the availability of a new AI-enabled True Wireless Stereo (TWS) Development Platform that will certainly be welcomed by developers and manufacturers globally, looking to accelerate the product development process, from entry-level to premium applications. The new TWS development kit shortens the design cycle for OEMs, enabling advanced, differentiated products with contributed technology from Alango Technologies and Chatable, among others.

Vesper introduced the VA1200, which the company calls the world’s first analog piezoelectric voice accelerometer (a.k.a. bone conduction sensor). This low-power vibration sensor can be used in true wireless earbud designs to pick up the wearer’s own voice through bone conduction. Using the VA1200 in conjunction with a standard microphone and a sensor fusion solution, the application can achieve superior background and wind noise reduction. Vesper calls this combination OnePlusOne.
