Ultra-Low-Power Voice User Interface Optimized for Smartphones, Tablets and other Mobile Devices
Eindhoven, Netherlands and Raanana, Israel – February 24, 2014 – NXP Semiconductors N.V. (NASDAQ: NXPI), a global provider of solutions that enable secure connections for a smarter world, and Rubidium Ltd., a global supplier of embedded speech processing technologies, have announced today the integration of Rubidium's multi-lingual Automatic Speech Recognition (ASR) and always-listening Voice Trigger engine into NXP’s CoolFlux™ DSP, an ultra-low power (ULP) licensable DSP core optimized for digital audio processing. The integration of Rubidium’s feature rich technology into the CoolFlux DSP provides NXP licensees with access to hands free voice trigger and later also speech recognition capability with beam forming, barge-in capability and a host of other voice user interface (VUI) functionalities. The technology will be demonstrated during the 2014 Mobile World Congress (NXP stand in Hall 7, E30).
Rubidium has been a recognized innovator in embedded speech processing technology for mobile devices, domestic appliances and consumer applications since 1995. With over 50 million products in the market, Rubidium's small-footprint multilingual voice user interface solutions include compelling solutions such as TTS, ASR, Voice Trigger, speech compression and playback as well as biometric speaker verification.
“We are pleased to offer our CoolFlux customers Rubidium's market proven technology,” says Johan Van Ginderdeuren, Director CoolFlux Licensing at NXP. “As an example, with only 0.5 MIPs in the quiet listening mode and 4 MIPs in the active trigger word recognition mode, we expect Rubidium’s Voice Trigger to typically consume only 28 microwatts on the CoolFlux DSP subsystem using an ULP 90nm library. This frees up resources for other activities on the DSP and minimizes power consumption while being always on. In addition, the small memory footprint provides for extended Rubidium functionalities such as biometric speaker verification.”
“Voice trigger and deeply embedded speech recognition have become a highly-requested feature in many consumer products such as mobile phones, hands free car-kits, wearable devices, automotive multimedia and infotainment and smart TVs,” states Shlomo Peller, CEO and Founder of Rubidium Ltd. “Rubidium’s ULP micro-embedded voice trigger and speech recognition draws considerably less power than other embedded product offerings, hence is a perfect fit for the NXP’s ULP CoolFlux DSP combining best of both low power worlds. One of the immediate benefits to CoolFlux DSP's developer base is the availability of a truly hands free voice user interface combined with low power consumption and very small memory profile.”
