example 1

[0137] This example provides a sound source localization device capable of implementing the aforementioned sound source localization method. For details, please refer to Figure 6 shown, including:

[0138] Audio collector: record the user's audio corpus through the microphone in the car, at least 2 microphones.

[0139] Voiceprint feature extraction model: Based on voiceprint recognition technology, collect the wake-up word audio files spoken by users, and classify different users through audio feature extraction (such as MFCC feature extraction algorithm).

[0140] Usually wake words are used for voiceprint recognition. The audio collector here is the aforementioned first collection module and / or the second collection module.

[0141] Sound source localization classifier: For a certain time range, the certain time range can suggest 1 day or half a day, 2 hours or 1 hour, etc., and count the frequency probability of the location source of each corpus spoken by the classifie...

example 2

[0150] Such as Figure 7 As shown, this example provides a sound source localization method, including:

[0151] voice recording;

[0152] Extract voiceprint features to identify user identity;

[0153] For the first authentication, set the preferred location information as the main driver;

[0154] Sound source localization obtains the angle θ of the sound source;

[0155] Determine if the angle θ is close to the median value of 90°,

[0156] If so, there is an error in the recognition angle θ;

[0157] If not, the recognition angle θ is reasonable;

[0158] If there is an error, determine whether there is only one person on the left of the main driver and the co-driver;

[0159] If there is only one person, obtain the location of the user, and directly determine the sound source based on the single user on the main driver or the co-driver;

[0160] If there is not only one person, use the search classifier to obtain the user's preferred position, and combine the prefe...

Abstract

The embodiment of the invention discloses a sound source localization method and device, localization equipment and a storage medium. The sound source localization method of the method includes: using the first collection module and the second collection module set at a distance from the first collection module to respectively collect the first voice signal to obtain the first voice signal of the sound source of the first voice signal. positioning information; identifying the identity information of the bearer object according to the voiceprint feature of the first voice signal; based on the identity information, obtaining the position preference information of the bearer object; correcting the first position preference information according to the position preference information The location information is used to obtain the second location information.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a sound source localization method and device, localization equipment and a storage medium. Background technique [0002] In a mobile device with a bearer space, there may be multiple bearer positions, and the bearer objects of these bearer positions may use voice to control the equipment in the bearer space. However, different bearing objects may control controlled devices in different locations, so it is necessary to distinguish the sound sources of the bearing objects from different bearing positions, but the current sound source localization has a problem of insufficient accuracy. Contents of the invention [0003] In view of this, the embodiments of the present invention expect to provide a sound source localization method and device, a localization device, and a storage medium. [0004] Technical scheme of the present invention is realized like this: [000...
