Problems solved by technology

[0003] However, the existing speech recognition solutions usually only support the recognition of Mandarin, and if the user uses a dialect, the recognition accuracy will be seriously reduced
Or although dialect recognition is supported, the user needs to manually select the recognition mode corresponding to the dialect, which requires the user's active cooperation. If the user's Mandarin and dialect are mixed, it is difficult to realize the initiative to switch modes, and in the scene of multi-person conversation , if there are speakers of multiple dialects, frequent switching will obviously lead to inefficiency and poor user experience

Embodiment Construction

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0066] The inventor found that the existing speech recognition scheme uses an independent dialect recognition model when performing dialect recognition. For example, to recognize the speech of the first dialect, the first dialect recognition model needs to be used. Voice, you need to use the second dialect recognition model, the first dialect and the second dialect are different dialects, the first dialect recognition model is obtained through the training corpus of the first dialect...

Abstract

Embodiments of the invention disclose a multi-dialect identification method, apparatus and device and a readable storage medium. Dialects are identified through a pre-built dialect identification model, wherein the dialect identification model is obtained through training of training corpora comprising multiple dialects, and the dialect identification model training process not only is limited tospeech contents of the corpora, but also introduces dialect categories to which the dialects belong; the dialect identification model is optimized by combining with the dialect categories to which thedialects belong, so that the dialect identification model can accurately identify the multiple dialects, a user does not need to perform switching of voice identification modes, the user operation issimplified, and the accuracy and efficiency of multi-dialect identification are improved.

Description

technical field [0001] The present application relates to the technical field of speech recognition, and more specifically, to a multi-dialect recognition method, device, equipment and readable storage medium. Background technique [0002] At present, more and more artificial intelligence application entrances rely on speech recognition, for example, translators that enable barrier-free communication between people of different languages ​​and countries, robot customer service that greatly reduces human resources, voice input methods that free hands, Controlling home appliances is more convenient and natural for smart homes (home appliances). Their entrances all rely on voice recognition, so the accuracy of voice recognition is particularly important. [0003] However, the existing speech recognition solutions generally only support the recognition of Mandarin, and if the user uses a dialect, the recognition accuracy will be severely reduced. Or although dialect recognition...
