STMicroelectronics Easily Adds Voice Control Features for Wearables and Remote Control

Published2015.06.26 15:26

STMicroelectronics (ST) has made adding voice control features much easier through its software-based innovation, BlueVoice.

Voice control helps to develop wearable technology more simply and battery-friendly.

The wearable sector is booming with the emergence of advanced products such as smartwatches. Market research firm IHS predicted that the wearable market would reach 135 million units in 2019, and that designs would become smarter and the number of sensors would increase to support advanced features.

Ease of use and battery life have already established themselves as important considerations for customers, and voice control can improve both by minimizing touchscreen usage.

ST’s market-leading wireless ICs, microcontrollers, and MEMS sensors are suitable for wearable products. The newly released software BlueVoice provides all the drivers and libraries necessary to implement Bluetooth Low Energy (Blue LE) voice transmission in systems composed of ST’s STM32 microcontrollers, BlueNRG ultra-low power network processors, and digital MEMS microcontrollers. It is provided in the form of a development board that allows for stacking, facilitating easy prototyping.

Bluetooth LE offers several advantages in conjunction with Wi-Fi and ZigBee for remote control units (RCUs) in home automation systems. ST's development platform utilizing BlueVoice is ideal for implementing voice and gesture control functions using MEMS microphones and motion sensors, enabling the creation of a more intuitive and natural user interface.

The new osxBlueVoice middleware and BlueVoiceLink software development kit (SDK), based on STM32Cube technology, are part of the open.AUDIO licensing program that supports developers working with ST's digital MEMS microphones. open.AUDIO connects to the STM32 open development environment, which provides substantial support to developers using STM32 ARM Cortex 32-bit microcontrollers in embedded projects.

The BlueVoiceLink SDK is available for free download at www.st.com/BlueVoiceLink for evaluation and development purposes. It operates easily using the licensing wizard tool included in the package, and volume licensing terms are provided in a simple manner suitable for enterprise use, making it convenient for competitively priced products.
