Audio file for teaching and production methods thereof

Abstract

The invention relates to the field of computer voice or sound processing, and discloses an audio file for teaching and six methods for producing the audio file. The audio file (203) is characterized by consisting of a plurality of sound clips (201) and a plurality of silence clips (202), wherein the silence clips (202) are added on purpose; and the sound clips (201) and the silence clips (202) alternately appear in the audio file. According to the audio file, following singing, following reading, following playing, playing control and publishing become relatively convenient and efficient. The first and second methods comprise splitting the silence clips (202) and then combining the silence clips (202); the third method comprises directly inserting the silence clips (202); the fourth method comprises directly recording the silence clips (202); the fifth method comprises generating the audio file by utilizing an audio database and inserting the silence clips (202); and the sixth method comprises synthesizing the audio file (203) with the silence clips (202) by utilizing a machine. According to the six production methods, the technical problems in production are well solved.

Description

technical field [0001] The invention relates to the field of computer speech or sound processing, in particular to an audio file of language and music sound materials and a production method thereof. Background technique [0002] Imitation is the basic way for humans to learn and acquire various skills. Starting from kindergarten, the basic way for people to learn language and music is that the teacher reads or sings a sentence, and the students read or sing a sentence, so as to achieve the purpose of familiarity and mastery. The same can be said for learning opera singing. Even when learning to play an instrument, the teacher will demonstrate the performance, and then the students will learn by imitation. This way of learning is the most natural way of learning. [0003] The recorded sound first existed in the form of a phonograph, and then existed in many formats such as tapes, CDs, MP3 formats, WMA formats, AAC formats (including but not limited to the above formats), ...

AI Technical Summary

Problems solved by technology

Therefore, these devices and software partially play the role of teachers; however, for teaching, traditional audio files have obvious defects: since all sound materials are continuous, such as continuous voice reading materials, continuous For song singing materials and continuous instrumental music performance materials, it is very inconvenient for students to imitate. Just after listening to a sentence, they are about to follow-up or imitate, and the next sentence has already started to play, resulting in simultaneous reading or imitation and the playback of the next sentence. , which will lead to inaccurate follow-up or imitation, it will be too troublesome if you manually pause every time

However, there are still some problems in the use of ordinary repeaters and software with repeating functions: first, the position of the sentence sentence is not accurate; It is because each sentence is repeated several times, the form is boring, and the learning process of phonetic materials seems fragmented, which is completely mechanical repetition, which is not conducive to overall understanding and mastery, for example, it is not conducive to overall understanding of an article or movement and improving the sense of language and music

The existence of these problems has a relatively large negative impact on the full use of computer technology and rich sound materials for learning language, singing, opera performances and musical instruments

[0005] Regarding the production technology of audio files, the latest method is to segment audio files and split them into several audio clips, each clip becomes a file, and then play files one by one, and control the playback according to certain parameters during playback. The number of repetitions and the length of the pause, this technology better solves the first and second problems of the above-mentioned repeater, but there are still the following problems: First, after splitting the larger audio file A large number of small files will be generated. For example, a 30-minute recording may be split into 400 small files. Too many files will make the playback interface look very untidy; second, special playback software or playback equipment is required for playback control to achieve the corresponding Third, repeating the same sentence multiple times is not conducive to grasping the connotation of a work as a whole; fourth, this processing method is not suitable for the publication and distribution of audio-visual materials. For example, it is impossible for a set of foreign language learning materials Supporting publication and distribution of thousands of audio files
