Sensory’s TrulyHandsfree wake word and phrase spotting technology is known for fast response, low power consumption, and excellent performance from a distance or in noisy environments. This technology is an integral component for fully featured voice control of devices in the home, car, and anywhere voice user interfaces could be deployed. Sensory’s technology is complementary to front-end processing solutions from other partners, such as DSP Concepts. It is available for Arm Cortex M4/M33/M7 cores and also for Cadence Xtensa DSP cores. TrulyHandsfree is compatible with the Sensory VoiceHub, enabling developers to quickly build models for custom commands and wake words with text input.
