摘要: The invention provides a method and system for dynamically estimating background noise comprising. includes portable communication device, vocoder, voice activated detector. Based on information received by the vocoder determines parameters related to incoming including voicing mode indicative of periodicity information. detector then compares threshold determine whether estimate should be updated. steps of: receiving indicator current comfort level an frame; comparing with predetermined if is equal previous level; maintaining exceeds revising does not exceed threshold.
