NCT Releases ClearSpeech for CSR's Bluetooth

NCT released its ClearSpeech technology for Cambridge Silicon Radio's BlueCore3. This development will enable Bluetooth developers to use NCT's noise and echo reduction technology on voice-based Bluetooth devices.

The BlueCore3 is a single-chip device that integrates Bluetooth technology with a 32 MIP open platform DSP co-processor and 16-bit stereo audio codec, providing a means of delivering signal processing solutions for Bluetooth applications.

ClearSpeech is a suite of software algorithms that provide noise cancellation for human listeners, noise cancellation for voice recognition, echo cancellation and signal conditioning.
