Problems solved by technology

[0003] In the prior art, when obtaining far-field recognition training data, one method is the direct recording method. However, this method has poor efficiency and data coverage, and cannot use the existing near-field recognition training data. In order to solve the direct The problem of the recording method can also use the acoustic transfer function (Acoustic transfer function, ATF) estimation method

Abstract

The invention provides a far field identification processing method and device. The far field identification processing method includes the steps: acquiring an ATF (acoustic transfer function) of an application environment according to an ATF acquired by an AEC (acoustic echo cancellation) module; acquiring near field identification training data; acquiring far field identification training data corresponding to the application environment according to the ATF of the application environment and the near field identification training data. According to the method, additional participation of a user can be omitted, and interference in the user is reduced, so that user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a processing method and device for far-field identification. Background technique [0002] Far-field recognition technology, that is, long-distance recognition technology, is usually used to solve the speech recognition request of the scene where the speaker is 2 meters away from the speech device. In far-field recognition, a far-field recognition model is used, and the far-field recognition model is established after training the far-field recognition training data. [0003] In the prior art, when obtaining far-field recognition training data, one method is the direct recording method. However, this method has poor efficiency and data coverage, and cannot use the existing near-field recognition training data. In order to solve the direct For the problem of the recording method, an estimation method of an acoustic transfer function (Acoustic transfer function, AT...
