Abstract
A selection method is implemented in electronic equipment and includes steps consisting of: acquiring and memorizing, for each microphone of the equipment, a first reference audio signal produced by said microphone from a reception by the set of microphones of a first reference sound signal; analyzing the first reference audio signals to produce at least one directional parameter representative of a direction of arrival of the first reference sound signal; selecting, according to the directional parameters from among the set of microphones, the first microphones which make it possible to maximize an effectiveness of a first voice recognition method.
