Abstract
A speech enhancement system for a remote microphone has a wireless receiver that receives a signal from a first microphone of a remote device. A delay buffer receives a second microphone signal from a second microphone and delays by an adjustable delay. The adjustable delay is based on a difference between a wireless delay and an acoustic delay. A noise suppressor produces an output audio signal for an earpiece speaker, based on the first microphone signal and the adjustable delayed second microphone signal. Other aspects are also described and claimed.
