Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0032] In the field of ASR speech recognition evaluation, the main evaluation scheme is to mark the video / audio text and the recognized text, and calculate the character error rate (Character Error Rate, CER) and sentence error rate (Sentence Error Rate, Sentence Error Rate, SER) index, but when the audio and video corpus is wrongly marked, it cannot be restored to the original text positioning. Without detailed context, it is not easy to find the context relationship between typos, which leads to inaccurate positioning analysis, so the practical value is low.

[0033] In view of the above problems, an evaluation method for multimedia text recognition is provided in the embodiment of the present application. figure 1 is a schemat...

Abstract

The invention discloses an evaluation method, device and equipment for multimedia text recognition and a readable storage medium, and relates to the field of interface interaction. The method comprises the following steps: displaying a multimedia uploading interface; receiving a file uploading operation in the multimedia uploading interface; a text recognition evaluation result is displayed based on the file uploading operation, the text recognition evaluation result comprises an alignment analysis result of the characters, and in the alignment analysis result, the alignment conditions of a first alignment position in the text recognition result and a second alignment position in the reference text content are expressed with corresponding expression features. According to the method, the intuitiveness of comparison between the text recognition result and the reference text content is improved, the recognition effect of the text recognition result can be directly reflected, and the efficiency and convenience of evaluating the text recognition result are improved.

Description

technical field [0001] The embodiments of the present application relate to the field of interface interaction, and in particular to an evaluation method, device, equipment and readable storage medium for multimedia text recognition. Background technique [0002] Automatic speech recognition technology (Automatic Speech Recognition, ASR) refers to recognizing the speech content to obtain the text content corresponding to the speech content, wherein the speech content can be a piece of audio content or an audio part in a piece of video. [0003] The evaluation process of ASR recognition refers to matching the text content obtained by ASR recognition with the standard content to determine the accuracy of the ASR recognition result. Usually, the word error rate and sentence error rate between the ASR recognition result and the standard content are calculated by the edit distance algorithm. Error rate. [0004] However, when the evaluation result of ASR recognition is determine...
