Bluetooth Handsfree Phone
A Bluetooth Handsfree Car Kit (HFCK) is a Digital Signal processing module for noisy automotive environments caused by engine, wind and other sources. The Wireless Bluetooth standard is highly compatible and easily integrates mobile phones to HFCK. The Blackfin® processor runs high quality acoustic echo cancellation AEC (VDA type 1), noise reduction, Bluetooth protocol stack and necessary user profiles, and highest quality speech-text recognition.
