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.
