Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] As a simple, convenient and efficient input method, speech recognition has changed the traditional keyboard mode based on complex coding or pinyin input, and provided convenient conditions for natural human-computer interaction. Especially in recent years, with the development of science and technology and the innovation and popularization of wireless communication networks, various online speech recognition applications, such as sending microblogs, writing t...

Abstract

The embodiment of the invention discloses a speech recognition method and system to solve the positioning inconvenience of the manually positioning by mentioned users. The speech recognition method comprises performing speech recognition for the speech signal input by users to obtain a speech recognition result and a speech clip corresponding to each character of the speech recognition result, receiving the error correction information input by the users to generate a corresponding error correction character string, obtaining at least one speech clip corresponding to the error correction character string as a candidate speech clip for the respective statistics of the likelihood of the each candidate speech clip on the error correction string model, determining the character string of the speech recognition result in the first optimal decoding path corresponding to the candidate speech clip as candidate character string according to the speech clip corresponding to each character string in the speech recognition result, calculating the error correction confidence coefficient of the candidate character string corresponding to the candidate speech clip according to the likelihood of the candidate speech clip and determining the error character string according to the error correction confidence coefficient, and replacing the error character string with the error correction character string.

Description

technical field [0001] The present invention relates to the technical field of voice recognition, and more specifically, to a voice recognition method and system. Background technique [0002] Speech recognition technology is a technology that recognizes voice signals entered by users and finally converts them into text / strings (that is, the recognition result is text), which provides convenience for natural human-computer interaction. Take mobile devices using speech recognition technology as an example. With the support of speech recognition technology, users only need to speak to the mobile device, and text will be automatically formed after being recognized by the speech recognition system, which greatly improves the user's input efficiency. [0003] However, in the application environment where large vocabulary is spoken freely, speech recognition technology still cannot achieve a 100% correct recognition rate, and manual correction and editing of the recognition result...
