STMicroelectronics and Sensory Inc. have announced a collaboration that will enable the STM32 microcontroller (MCU) user community to develop and prototype intuitive voice-based user interfaces for a wide range of smart embedded products. The joint efforts pair ST's STM32 hardware and software with Sensory's voice-control technologies, including the new VoiceHub online portal that supports seamless creation of embedded speech-recognition models using custom wake words, voice-control command sets, and large natural-language grammars in almost twenty languages and dialects. The solution is based on an STM32Cube software extension package and runs on a high-performance STM32H7 MCU, taking advantage of its architecture, internal Flash, SRAM, and high CPU speed.

This combination plays a key role in increasing voice-control accuracy and minimizing command-recognition time. Hosting the voice application and speech models in the generous on-chip memory of the high-performance STM32 MCUs further boosts the system integration and ease of use, as well as lowers cost of ownership.
