Cypher's algorithms are based on a neural network analysis of human speech, which can tell a human voice from other sound sources and isolate it. The voice isolation software can significantly improve the clarity and intelligibility of the speech, even in noisy environments. The CEVA-TeakLite-4's powerful processing capabilities combined with its small footprint and very low power consumption make it ideal to implement DSP-intensive algorithms such as Cypher's voice isolation.

John Walker, CEO of Cypher, stated: "The breadth of applications for voice technology in recent years has expanded beyond handsets to include a whole new range of devices deploying voice activation and control. Our patented voice isolation technology significantly boosts clarity as it eliminates over 99% of background noise and also improves speech recognition as it cuts the word error rate by 40% in noisy environments. The CEVA-TeakLite-4 DSP is fully equipped to handle any use case, delivering outstanding performance within a highly compact memory footprint."

Moshe Sheier, director of product marketing, audio and voice at CEVA, stated: "The CEVA-TeakLite family is the industry standard DSP for integrated audio and voice, having powered more than four billion devices to date. We are pleased to add Cypher's voice isolation solution to our rich ecosystem. Cypher brings a unique solution for enhancing voice calls and enables a whole new range of applications where voice activation technology can be utilized for the Internet of Things and beyond."
