Cirrus Logic Releases New Voice Processors for Mobile Apps

Cirrus Logic, a provider of high-precision analog and digital signal processing components, is extending its portfolio with a new line of voice processors for mobile applications. The ultra-low power Cirrus Logic CS48LV12/13 voice processors with integrated SoundClear technology improve voice recognition accuracy in smartphones, tablets, and wearables by improving voice quality, eliminating background noise, and delivering clear communications in any environment.

Cirrus Logic's SoundClear technology features single/dual microphone noise suppression and acoustic echo cancelation for both narrow and wideband audio content, providing manufacturers with a complete hardware and embedded software product capable of delivering better voice recognition and clearer phone conversations in handset or speakerphone mode.

"Voice-enabled interface features will continue to fuel growth in mobile devices yet will require superior signal processing technology to give consumers an exceptional user experience," said Jason Rhode, president and CEO of Cirrus Logic, in a statement. "Cirrus Logic provides complete IC solutions that leverage our audio DSP hardware and advanced SoundClear embedded software to ensure superior voice performance anytime and anywhere."

To enable always on voice wakeup of mobile devices, the CS48LV13 supports TrulyHandsfree technology from Sensory. By combining TrulyHandsfree technology with SoundClear ASR Enhance, ultra-low power voice detection, optimized hardware, and intelligent system control, the CS48LV13 provides customers a solution for using voice as an interface to wake up a device and the ability to always be active and on, without eroding the customer experience due to observed battery life reduction.

Implemented and optimized on the industry's smallest, lowest-power audio DSP, the 32-bit CS48LV12/13 includes advanced multimedia software to enable a variety of audio and voice enhancements.

Cirrus Logic's SoundClear technology has been shipped in more than 75 million units representing more than 135 products, including leading smartphones, tablets, Bluetooth speakers, and automotive entertainment systems.
