STMicroelectronics has recently uncloaked a software-based innovation that allows voice control to make wearable technology simpler and more battery-friendly. According to the company, the BlueVoice software allows designers to get all the drivers and libraries they need to implement voice transmission over a Bluetooth Low Energy connection in systems built around ST's STM32 MCUs, BlueNRG ultra-low-power network processors and digital MEMS microphones. All these are available in stackable development boards for easy prototyping.

Bluetooth Low Energy also offers advantages alongside WiFi and ZigBee in remote-control units (RCUs) for home-automation systems. ST's development platform with BlueVoice software is geared for implementing voice and gesture control using a MEMS microphone and motion sensors, to implement a more intuitive and natural user-interface.

Based on the STM32Cube platform, the osxBlueVoice middleware and BlueVoiceLink software development kit (SDK) are part of the open.AUDIO licensing programme, which supports designers working with ST's MEMS digital microphones. open.AUDIO is linked to the STM32 Open Development Environment, which provides powerful support for designers using STM32 ARM Cortex 32bit MCUs in embedded projects.

The BlueVoiceLink SDK can be downloaded free of charge for evaluation and development at www.st.com/bluevoicelink-nb. Activation is easy using the licensing wizard tool included in the distribution package, and volume-license terms are straightforward and business-friendly for use in competitively-priced end products.
