Embodiment 1

[0020] figure 1 The implementation flow of the subtitle processing method provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0021] In step S11, the first subtitle data corresponding to the multimedia file is obtained, and the audio data of the multimedia file is extracted.

[0022] In the embodiment of the present invention, the multimedia files include video files or audio files, wherein the audio files include but not limited to songs and audio novels. The file formats of video files include but not limited to MP4 format, WEBM format and MOV format; the file formats of audio files include but not limited to MP3 format and AAC format.

[0023] Wherein, subtitle data includes but not limited to subtitle text and time stamp. In the embodiment of the present invention, the subtitle data can be generated by means of manual translation and / or machine translation. According to the different translation methods of the subtitle text of th...

Embodiment 2

[0043] Figure 4 The subtitle processing apparatus 100 provided by Embodiment 2 of the present invention is shown, including an acquisition unit 110 , an identification unit 120 and a correction unit 130 .

[0044] The acquiring unit 110 is configured to acquire the first subtitle data corresponding to the multimedia file, and extract the audio data of the multimedia file;

[0045] A recognition unit 120, configured to perform speech recognition processing on the audio data to generate second subtitle data;

[0046] A correction unit 130, configured to correct the first subtitle data based on the second subtitle data.

[0047] An embodiment of the present invention provides a device for processing subtitles. The device first acquires first subtitle data and audio data corresponding to the first subtitle data, and then performs speech recognition on the audio data to obtain The obtained audio data is used to correct the original subtitle data. Since the entire correction proc...

Embodiment 3

[0053] Figure 6 It is a schematic diagram of a subtitle processing terminal provided in Embodiment 3 of the present invention. Such as Figure 6 As shown, the terminal 200 in this embodiment includes: a processor 230 , a memory 210 , and a computer program 220 stored in the memory 210 and operable on the processor 200 . When the processor 230 executes the computer program 220, it realizes the steps in the embodiment of the above subtitle correction method, for example figure 1 Steps S11 to S13 shown, or, when the processor 230 executes the computer program 220, the functions of the units in the above-mentioned embodiments of the device 100 are realized, for example Figure 4 Functions of units 110 to 130 shown.

[0054] Exemplarily, the computer program 220 can be divided into one or more units, and the one or more units are stored in the memory 210 and executed by the processor 230 to implement the present invention. The one or more units may be a series of computer prog...

Abstract

The invention is applicable to the technical field of multimedia, and provides a subtitle processing method and device and a terminal, and the method comprises the steps: obtaining first subtitle datacorresponding to a multimedia file, and extracting audio data of the multimedia file; performing voice recognition processing on the audio data to generate second subtitle data; and correcting the first caption data based on the second caption data. According to the method, the caption to be corrected and the audio frequency are acquired firstly, then the audio frequency is subjected to voice recognition, the first caption data are corrected according to the second caption data obtained after recognition, manual participation is not needed in the whole correction process, and therefore automatic correction of the caption text is achieved, and the problem that manual correction is long in time consumption is solved.

Description

technical field [0001] The invention belongs to the field of multimedia technology, and in particular relates to a subtitle processing method, device and terminal. Background technique [0002] With the development of information technology, there are more and more global cultural exchanges, and foreign cultures have more and more influence on domestic culture. Among them, foreign pop music and videos have the most and most direct influence on domestic culture. For audio and video resources imported from abroad, in order to adapt to listening and watching by more people and improve people's use experience, it is usually necessary to add subtitles to the audio and video resources. [0003] Taking video subtitles as an example, the operation of adding subtitles usually requires attention to two aspects: first, the time alignment between the video playback content and the subtitles; second, accurate translation of the voice played in the video. Similarly, the correction of sub...
