Problems solved by technology

Audio matching technology focuses on the matching of the feature values ​​of the audio itself. This method also cannot meet the needs of full-text search of audio files according to the content of the audio files.
At the same time, this method has strict requirements on the input audio information, not only requiring the content of the input audio information to be consistent with the content of the audio files in the audio resource library, but also requiring the frequency and energy of the audio information to be consistent with the audio files in the audio resource library. Only when the frequency and energy of the frequency are close to each other can they be successfully matched, resulting in low efficiency of audio search and poor usability
[0006] The audio search technology provided in the prior art does not provide a full-text search solution based on the content of the audio file, and the audio search has low accuracy, low efficiency, and poor usability

Embodiment 1

[0057] This embodiment provides a local search solution for voice information in audio files. The corresponding audio resource library (may be referred to as a local audio resource library) is set on the terminal side, specifically the local storage in the user's terminal device. For local search of voice information, the device for searching voice information in audio files provided by the embodiment of the present invention needs to be set in the terminal equipment of the user. Local search process for voice information in audio files, such as image 3 As shown, it includes the local search preparation phase and the local search execution phase. The local search preparation phase includes the following steps:

[0058] S301. The terminal device extracts an unprocessed audio file from the audio resource library, and performs voice analysis on the current audio file;

[0059] S302, the terminal device judges whether the current audio file includes voice information according ...

Embodiment 2

[0072] This embodiment provides a network search solution for voice information in audio files. The corresponding audio resource library (may be referred to as a local audio resource library) is set on the network side, specifically a website database. In order to realize the network search for the voice information in the audio file, it is necessary to set this in the website server of the website providing the audio search service. The embodiment of the invention provides a search device for voice information in audio files. Network search process for voice information in audio files, such as Figure 4 As shown, it includes the network search preparation phase and the network search execution phase. The preparatory stage of network search includes the following steps:

[0073] S401. The website server extracts an unprocessed audio file from the audio resource library, and performs speech analysis on the current audio file;

[0074] S402, the website server judges whether ...

Abstract

The invention discloses searching method and device of voice information in audio files and equipment, which are used for realizing the text search on the contents of the audio files, improving the accuracy and the efficiency of the audio file searching and improving the usability of the audio file searching. The searching method comprises the following steps of: carrying out voice identificationon each audio file comprising voice information in the audio resource base, converting the audio files into text files comprising text information, and carrying out participle processing on text information of each text file; extracting key words included by corresponding audio files according to words included by each text file, determining the relevance of key words included by each audio file,and establishing an index database of the key words through being combined with the relevance information of each audio file; carrying out specific key word matching in the index database while receiving the voice information searching request carrying the specific key words, and providing the corresponding audio files according to the relevant information of the audio files with the relevance with the specific key words.

Description

technical field [0001] The invention relates to the technical field of audio search, in particular to a search method, device and equipment for voice information in audio files. Background technique [0002] In the information age where the amount of information grows geometrically, search technology has become one of the essential key technologies in people's work and life, enabling people to quickly and accurately search for the information they need from the ocean of information, thus greatly improving the Improve work and life efficiency. As search technology matures and its applications become more and more extensive, people's requirements for search technology are also increasing, and the demand for audio search is increasing. [0003] Existing audio search technologies mainly include the following two methods: [0004] Method 1: manually add text information to the audio file in advance, that is, create a tag for the audio file, and search for the tag of the audio f...
