• Ultra-low power voice processing and MEMS microphone circuitry enables sound detection and keyword recognition in a miniaturized single package
  • Combines ST's MEMS microphone and packaging know-how with DSP Group's voice - processing expertise and Sensory's voice-recognition firmware

BARCELONA, Spain, Feb. 27, 2017 (GLOBE NEWSWIRE) -- STMicroelectronics (NYSE:STM), a global semiconductor leader serving customers across the spectrum of electronics applications and a top MEMS supplier, DSP Group Inc. (NASDAQ:DSPG), a leading global provider of wireless chipset solutions for converged communications, and Sensory Inc., the leader in voice interface and keyword-detect algorithms, have revealed details for a highly power-efficient, voice-detecting and -processing microphone that delivers keyword-recognition capabilities in a compact package.

The small System-in-Package (SiP) device integrates a low-power ST MEMS microphone enabled by DSP Group's ultra-low power voice-processing chip and Sensory's voice-recognition firmware. The solution leverages ST's advanced packaging technology to achieve a powerful yet lightweight package, extremely long battery runtimes, and advanced functionality.

Although typical wake-on-sound microphones eliminate the need for users to touch the device to wake it from sleep mode, they suffer from limited processing power and wake the main system processor to recognize the received instruction. Using the powerful computation capabilities from DSP Group, ST's microphone detects and recognizes instructions without waking the main system, enabling energy-efficient, intuitive and seamless interactions for users speaking to voice-operated appliances like smart speakers, TV remotes, and smart home systems.
