Method for ordering song by voice

Abstract

The invention relates to a voice song-selecting method, which belongs to song-selection application technology. The invention is characterized in that a data initialization module containing files of Chinese character database and a similarity metric value chart of initials and finals of Chinese syllables, a song database character pre-processing module containing character strings of target syllable chains corresponding to the name of the song or the name of the singer, a voice recognition module for converting the voice recording data of the name of the song or the name of the singer input from the sound card into the corresponding character strings of Chinese characters, a recognition result post-processing module for converting the character strings of Chinese characters into the character strings of source syllable chains, and a searching and matching module for calculating the difference value based on the metric of the similarity between initials and finals according to the character strings of target syllable chains corresponding to the name of the song or the name of the singer and the character strings of source syllable chains obtained from the recognition result post-processing module, Besides calculating the integral difference by using the dynamic programming method and outputting the result of the minimum difference value. The average button pressing time and the average operating time of song-selection are reduced, and the efficiency of song-selection operation is greatly enhanced.

Description

technical field [0001] The present invention relates to a voice-on-demand method for selecting songs on demand according to the operator's voice (song name or singer name); A voice song request method that searches and selects songs by comparing names or singers' masterpieces. Background technique [0002] The traditional way of ordering songs includes: song name number retrieval, first character stroke retrieval, song category retrieval, etc. Due to the large number of songs (usually more than 10,000), operators often need to enter multi-layer menus and browse multiple pages. In order to find the target song, the way to find the song is not friendly and inefficient. Taking the commonly used song name number retrieval method as an example, if you want to play the song "Rain or Rain", the operator needs to select "Song name number retrieval" first, and then select "Four-character song". There are hundreds of four-character songs, while Only ten to twenty songs can be displa...

AI Technical Summary

Problems solved by technology

However, because the accuracy and fault tolerance of speech recognition itself are not high enough, it is very difficult to provide speech application products with real practical value, which also leads to many speech application systems only for demonstration purposes, but not for actual use. The effect is not ideal

[0004] The present invention aims at the disadvantages that the current way of ordering songs is not friendly and efficient enough. On the basis of the existing voice recognition technology, the expression method of the syllable chain and the matching method with high accuracy and fault tolerance enable the operator to easily pass Voice order song operation
