Intelligence and understanding starts with a crystal-clear signal.

Speech Signal Enhancement

Speech Signal Enhancement

A comprehensive solution to improve hands-free speech communication and recognition in noisy environments

In order to be understood, we must first be heard. That’s why Cerence Speech Signal Enhancement (SSE) is a critical piece of our platform. SSE is a suite of sound processing technologies that remove noise from microphone inputs, teeing up our world-class voice recognition and natural language understanding engines to work their magic with crystal-clear input from drivers and passengers.

SSE is critical to the in-car experience, enhancing speech quality for phone calls, enabling drivers to effectively use wake-up words and seamlessly interrupt and interact with the assistant, and allowing us to create speaking zones so the assistant knows exactly who is speaking – and who might need to be muted. In the future, SSE will be even more critical. Imagine a shared, autonomous vehicle with multiple passengers on board. SSE will allow individual passengers to interact with the vehicle without confusion or interruption.
