All-in-one reference designs plus high-performance audio
front end ease development of smart-home devices and
SANTA CLARA, Calif.,
Nov. 17, 2020 /PRNewswire/
-- STMicroelectronics (ST; NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics
applications, and DSP Concepts today announced four new
high-performance audio front ends (AFE) with AVS qualified
integrated voice processing. Launched as TalkTo for ST, the designs
cover Alexa Voice Service for AWS
IoT, near-field for wearables, speakerphones, and point-of-sale
kiosks. Through this partnership, DSP Concepts ensures products
based on these designs can be used for Alexa Built-in products
using simple microcontrollers (MCUs).
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
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
Daniel Colonna, Marketing Director,
Microcontroller Division, STMicroelectronics. "Our reference
design, one of the first to be approved by AWS, leverages the
inherent strengths of STM32 microcontrollers and the supporting
ecosystem to enable cost-efficient products with unbeatable
functionality, small size, and fast time to market."
"We are at the very beginning of the voice-enabled device
revolution," said Chin Beckmann,
co-founder and CEO of DSP Concepts. "From shopping kiosks to
automobiles, voice has consistently struggled outside the home.
Companies like ST and partnerships like ours will trigger the next
massive shift: enabling the proliferation of high fidelity,
low-cost solutions into environments in and out of the home, once
considered too noisy for effective voice interaction."
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

ST Voice is AVS 2.1 Certified for AWS IoT with mono & stereo
AEC and Adaptive Interference Canceller™ for reliable 'barge-in' at
6+ meters. The extensible two-mic reference designs are wake-word
and ecosystem agnostic, with integrated playback processing.
