Low Power Speech Detection Enables Under 25 µW
SANTA CLARA, Calif. February 25, 2013 Tensilica, Inc. and Sensory today announced that the two companies have worked together to provide the lowest power voice activation solution based on Tensilicas recently introduced HiFi Mini DSP (digital signal processor) IP core and Sensorys TrulyHandsfree always-on voice activation technology. By utilizing Sensorys Low Power Speech Detection technology, Tensilica was able to further reduce power to an average of under 25 µW when implemented in a 28 nm HPL process, the lowest power implementation by far in the industry. This makes this joint solution ideal for always-on voice activated smartphones, tablets, appliances and automotive applications.
Tensilica and Sensory will demonstrate their joint voice solution at Tensilicas booth, #6D101 at the Mobile World Congress, February 25-28, in Barcelona, Spain.
The Low Power Speech Detection capability significantly extends battery life, stated Bernard Brafman, vice president of business development at Sensory. When the HiFi DSP detects speech, the full TrulyHandsfree 3.0 voice trigger features, including speaker verification passphrase, user-defined speaker verification and user-defined speaker identification, will be enabled.
Using Sensorys TrulyHandsfree technology, we can offer our customers the lowest power total solution, with power ranging from below an average of 25 µW in basic detection mode, stated Larry Przywara, Tensilicas senior director of mobile multimedia. With this level of efficiency, Sensorys voice trigger running on our HiFi DSP is the smallest part of the power budget for the entire voice signal chain.
Sensorys TrulyHandsfree 3.0 technology enables personalization of the user experience by calling up a specific users history, preferences and settings. Sensorys speaker verification technology uses voice biometrics and analysis to authenticate a specific individual. Sensorys TrulyHandsfree complete set of voice activation and recognition products allow users to access a device with just their voice, bypassing the typical 4-digit number manually entered on the screen for access.
