Abstract (en)
[origin: WO2015082807A1] The invention relates to a voice detection method which makes it possible to detect the presence of voice signals in an noisy acoustic signal x(t) from a microphone, comprising the following consecutive steps: calculating a detection function FD(τ) based on calculating a difference function D(τ) varying in accordance with the shift τ on an integration window with length W starting at the time t0, with: a step of adapting the threshold in said current interval, in accordance with values calculated from the acoustic signal x(t) established in said current interval; searching for the minimum of the detection function FD(τ) and comparing said minimum with a threshold, for (τ) varying in a predetermined time interval referred to as current interval so as to detect the possible presence of a fundamental frequency F0 that is characteristic of a voice signal in said current interval.
