STMicroelectronics & DSP Concepts Partner to Simplify Creation of Alexa Built-In Smart Home Devices with AWS-Qualified Reference Designs
All-in-one reference designs plus high-performance audio front end ease development of smart-home devices and appliances

Powered by DSP Concepts, TalkTo for ST jump-starts the design of a wide range of devices based on the high-performing STM32* MCU family. The energy-efficient STM32 is the world's most successful in the 32-bit Arm® Cortex®-M MCU family and is ideal for low-cost, small, and simple connected devices requiring state-of-the-art features like far-field audio capture and natural-language understanding.
Combined with the DSP Concepts' suite of proprietary Machine Learning & Microphone Processing algorithms, the two-mic solutions feature dynamic beam steering alongside noise reduction and adaptive interference cancellers to interference with no reference signal required. TalkTo for ST allows OEMs to rapidly meet the growing demand for high performance voice in a wide variety of environments.
"AVS Integration for AWS IoT Core can revolutionize users' expectations of smart devices by enabling easier access to their powerful features and delivering more rewarding experiences," said
"We are at the very beginning of the voice-enabled device revolution," said
ST's AVS Integration for AWS IoT Core reference design contains a compact 36mm x 65mm main board that combines a high-performance STM32H743 MCU and Wi-Fi module. Unlike other devices commonly used for Alexa products, STM32 MCUs integrate all necessary system features, including powerful audio front-end processing, local wake-word detection, communication interfaces, and memory in a single chip. This creates a small board with a simple layout for cost-effective deployment in customers' end products.
TalkTo delivers outstanding far-field voice detection, even in noisy environments and with closely spaced microphones. The partnership between ST and DSP Concepts also gives OEMs instant access to:
- Audio Weaver: graphical tool to customize & tune audio processing models with embedded engine for Cortex-M4 and M7
- Voice-UI Quick-start Bundle: need-to-know design guidelines and tools
-
