Problems solved by technology

[0004] 1) The radio and television industry often has special processing and operations for speech recognition that are different from other industries. However, because the above-mentioned traditional speech recognition is applied to various industries, it is not targeted for the radio and television industry, and cannot be based on the characteristics of the radio and television industry. Filtering of non-speech content in broadcast TV data
Because non-speech content is not within the scope of processing for speech recognition in the radio and television industry, if non-speech content is not filtered, it needs to be transmitted and processed, which not only leads to waste of transmission resources and computing resources, but also It will also cause more misrecognition op

Embodiment 1

[0061] Embodiment 1 of the present invention provides a radio and television voice recognition method, the steps of which are as follows figure 1 As shown, it specifically includes the following steps:

[0062] Step S1, extracting audio data according to broadcast TV data.

[0063] Step S2, preprocessing the audio data to obtain feature text data.

[0064] Step S3, sending the characteristic text data to the cloud server for recognition processing, and obtaining male and female voice recognition, speaker recognition and speech recognition results;

[0065] Step S4, performing fusion and structured text identification on data preprocessing, male and female voice recognition, speaker recognition and speech recognition results to generate a structured speech recognition result.

[0066] The above method first extracts the audio data from the radio and television data to be identified (that is, audio and video data) provided by the user, and obtains the characteristic text data ...

Embodiment 2

[0128] Embodiment 2 of the present invention also provides a radio and television speech recognition system, the composition diagram is as follows Figure 5 As shown, the system includes:

[0129] An extracting unit 10 extracts audio data according to broadcast television data;

[0130] The preprocessing terminal 20 preprocesses the audio data to obtain feature text data and sends it to the cloud server 30;

Abstract

The invention discloses a broadcast television voice recognition method and system. The method comprises the following steps: extracting audio data according to broadcast television data; pre-processing the audio data to obtain feature text data; transmitting the feature text data to a cloud server for recognition to achieve male and female voice recognition, speaker recognition and voice recognition results; fusing the male and female voice recognition, speaker recognition and voice recognition results and marking a structured text to generate a structured voice recognition result. According to the method, the conventional voice recognition method is improved; various broadcast television data pre-processing technologies and broadcast television voice recognition methods are integrated; voice data is identified to meet data processing requirements in broadcast television industry; various recognition results are integrated to generate the structured voice recognition result; basic data can be provided for intelligent processing of other service of subsequent broadcast television programs; processing speed is increased; the accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of audio and video processing, in particular to a radio and television voice recognition method and system. Background technique [0002] At present, in the field of radio and television, traditional speech recognition methods suitable for various industries are mainly used for radio and television speech recognition, and traditional speech recognition mainly uses pattern matching method, which is divided into two stages: training and recognition. In the training stage, the user will Each word in the vocabulary is read or spoken in turn, and its feature vector is stored as a template in the template library; in the recognition stage, the feature vector of the input speech is compared with each template in the template library in turn, and the The one with the highest similarity is output as the recognition result. [0003] But the voice recognition of this voice recognition application has the following pro...
