A selection method, implemented in electronic equipment which comprises a set of microphones comprising a total number of microphones and which is used to implement a first voice recognition method requiring a first number of first microphones strictly less than the total number of microphones, the first number being equal to two, the selection method comprising steps consisting of: acquiring and memorizing, for each microphone from the set of microphones, a first reference audio signal produced by said microphone from a reception by the set of microphones of a first reference sound signal, the first reference sound signal comprising a first keyword activating the first voice recognition method; analyzing the first reference audio signals to produce at least one directional parameter representative of a direction of arrival (Da) of the first reference sound signal; selecting, according to the directional parameter(s), from among the set of microphones, the first microphones which make it possible to maximize an effectiveness of the first voice recognition method the analysis step comprising steps consisting of: determining, by using the first reference audio signals produced by the set of microphones, the direction of arrival (Da) of the first reference sound signal; defining from among the set of microphones, pairs of microphones and, for each pair of microphones: configuring a path formation module using the microphones of said pair of microphones to focus the path formation module in the direction of arrival; applying at the input of the path formation module, the first reference audio signals produced by the two microphones of said pair of microphones, and acquiring an output signal from the path formation module; applying a detection method aiming to detect the first keyword in the output signal, and conferring to the pair of microphones, a confidence score quantifying a probability of detecting the first keyword; and the selection step consisting of selecting as first microphones, the two microphones of the pair of microphones which has the highest confidence score. acquiring and memorizing, for each microphone from the set of microphones, a first reference audio signal produced by said microphone from a reception by the set of microphones of a first reference sound signal, the first reference sound signal comprising a first keyword activating the first voice recognition method; analyzing the first reference audio signals to produce at least one directional parameter representative of a direction of arrival (Da) of the first reference sound signal; selecting, according to the directional parameter(s), from among the set of microphones, the first microphones which make it possible to maximize an effectiveness of the first voice recognition method determining, by using the first reference audio signals produced by the set of microphones, the direction of arrival (Da) of the first reference sound signal; defining from among the set of microphones, pairs of microphones and, for each pair of microphones: configuring a path formation module using the microphones of said pair of microphones to focus the path formation module in the direction of arrival; applying at the input of the path formation module, the first reference audio signals produced by the two microphones of said pair of microphones, and acquiring an output signal from the path formation module; applying a detection method aiming to detect the first keyword in the output signal, and conferring to the pair of microphones, a confidence score quantifying a probability of detecting the first keyword; configuring a path formation module using the microphones of said pair of microphones to focus the path formation module in the direction of arrival; applying at the input of the path formation module, the first reference audio signals produced by the two microphones of said pair of microphones, and acquiring an output signal from the path formation module; applying a detection method aiming to detect the first keyword in the output signal, and conferring to the pair of microphones, a confidence score quantifying a probability of detecting the first keyword; and the selection step consisting of selecting as first microphones, the two microphones of the pair of microphones which has the highest confidence score.
