ON Semiconductor's BelaSigna R281 Enables Voice Activation in Portable Devices

ON Semiconductor, driving energy efficiency innovations, has introduced BelaSigna® R281, a new “always listening” voice trigger System-on-Chip (SoC) solution designed for popular consumer electronics devices such as smartphones, tablets and wearable devices. Using an audio pattern-matching algorithm developed by ON Semiconductor, BelaSigna R281 can detect a single, user-trained trigger phrase. This phrase can be any series of sounds, and is neither speech nor language dependent. Upon recognizing this trigger phrase, BelaSigna R281 will assert a wake-up signal which, when connected to a host controller, alleviates the need for users to touch their device to wake it prior to use.
