CEVA, NXP Software Partner to Deliver Enhanced HD Voice Processing

CEVA, a provider of digital signal processing (DSP) cores, and NXP Software, a mobile multimedia software provider, have partnered to deliver an enhanced HD voice processing solution for smartphones. The solution integrates NXP Software's LifeVibes VoiceExperience software with the CEVA-TeakLite family of DSPs, including the CEVA-TeakLite-4.

Through the partnership, NXP Software has ported and optimized its technologies in speakerphone and multi-microphone noise suppression, acoustic echo cancellation, and voice quality, onto CEVA's DSP platform, which has powered audio/voice processing in more than 2 billion devices to date. 

For the dozens of CEVA customers, the partnership with NXP enables them to add HD voice processing into their existing designs. For licensees of the CEVA-TeakLite-III and CEVA-TeakLite-4 DSPs, the VoiceExperience algorithms can further harness the low power, native 32-bit, high-performance voice capabilities to deliver better voice clarity and extended battery life. 

"There is a clear trend towards enhanced voice quality in smartphones today, combining advanced hardware and software techniques, including voice pre-processing and new multi-microphone configurations, to reduce background noise and improve voice clarity," said Nicolas Sauvage, director of marketing and sales at NXP Software, in a statement. "The CEVA-TeakLite-4 DSP delivers outstanding performance for these demanding applications, allowing our customers to gain maximum benefit from our VoiceExperience software package, and at lower power consumption." 

NXP's VoiceExperience enables natural communication over phone networks and IP-based channels such as Skype and Google Talk. It improves the intelligibility of speech, eliminates echo and distortion, and minimizes stationary and non-stationary background noise (such as traffic or crowds). VoiceExperience uses the same engine for voice calls, video telephony, and VoIP, and is HD voice compatible. Its HD voice compatibility ensures the voice sounds clear and natural, with improved intelligibility on all types of phones and mobile devices.

"We are pleased to collaborate with NXP Software, a world renowned provider of advanced voice applications. Our CEVA-TeakLite DSP family has become the industry standard for advanced audio and voice [system on a chip] solutions thanks in part to the large, robust partner ecosystem providing support for such advanced audio and voice applications," said Eran Briman, vice president of marketing at CEVA, in the statement. "With the LifeVibes VoiceExperience software optimized for our latest CEVA-TeakLite-4 DSP, we have significantly enhanced the HD voice processing capabilities available to product developers today."
