Patent ID: 8064591

Claim:
A signal processing method for enhancing sound pick-up in a telephone and/or videophone equipment, said equipment comprising at least one microphone and at least one loudspeaker, the method comprising: β) a signal from the microphone is compared with a low limit value (THR_LOW), and γ) the signal from the microphone is amplified if said signal from the microphone is less than the low limit value, wherein, prior to the comparison step β): α) a signal intended to feed the loudspeaker is compared with a chosen threshold (BDF d ), and the application of step γ) for amplifying the signal from the microphone is conditional on the result of the comparison of the signal intended to feed the loudspeaker in step α), the method further comprising a step of: comparing the signal from the microphone with a threshold corresponding to a local background noise level (BDF 1 ), the comparison of step β) with the low limit value (THR_LOW) is conducted if the level of the signal from the microphone is greater than said local background noise.
