Tensilica has DSP core for voice control in smartphones

Tensilica claims to have developed the ”smallest, lowest power DSP IP core” supporting always listening voice trigger and speech command modes. 

Aimed at voice control in smartphones and automotive applications, Tensilica is working with Sensory and other software partners that will provide the voice-activation, speech command recognition, voice pre-processing and noise reduction products optimised for the HiFi Mini DSP core.

The core uses 40-bit encoding, which significantly improves code size.

It also uses 16-bit instructions that are optimised for voice and audio codecs.

“Power is the single most important factor in enabling always-on listening capability in mobile devices,” said Larry Przywara, Tensilica’s senior director of mobile multimedia. 

“Using Sensory’s Truly Handsfree voice control technology, HiFi Mini is able to achieve less than 88µW of power for the core in 28 nm HPL, achieving both the lowest power consumption and uncompromising accuracy for speech recognition.”

“As voice control emerges as the natural interface, we expect it will become more ubiquitous as it migrates to automotive, consumer appliances and potentially industrial control,” said Przywara.

The HiFi Mini DSP IP core will be available in March 2013.

Tensilica will demonstrate Sensory’s Truly Handsfree voice trigger and speech command products on HiFi Mini at the Consumer Electronics Show in Las Vegas next week.
