Hands free car acoustic echo audio suppression technique has APA type algorithm adaptively/dynamically noise/echo modifying received speech signal
The acoustic echo audio suppression technique has a signal detected by a microphone (Sn) and speaker signals. The suppression technique uses an APA algorithm which is modified adaptively and dynamically as a function of noise level and of reflected echoes at each instant.
