Embodiment 1

[0060] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0061] The invention provides a kind of karaoke intelligent guiding method based on audio information, comprising the following steps:

[0062] S1: Receive the audio information collected by the audio collector in real time and store it in the cache;

[0063] Wherein, the S1 is specifically:

[0064] The audio data in PCM format collected by the audio collector at a preset sampling rate is acquired through the set-top box, and the audio data is stored in the buffer memory of the set-top box.

[0065] Wherein, the acquisition rate is 16KHz;

[0066] S2: Obtain the collected audio information from the cache, and calculate the average decibel value corresponding to the audio information within a preset time;

[0067] Wherein, the S2 is specifically:

[0068] Obtain in real time the audio information stored in the cache within the preset time, obtain the first audio information, analyze the first au...

Embodiment 2

[0077] Please refer to figure 2 , the second embodiment of the present invention is:

[0078] The present invention provides a kind of karaoke intelligent guiding system based on audio information, comprising a memory 1, a processor 2 and a computer program stored on the memory 1 and operable on the processor 2, the processor executes the computer The following steps are implemented in the program:

[0079] S1: Receive the audio information collected by the audio collector in real time and store it in the cache;

[0080] Wherein, the S1 is specifically:

[0081] The audio data in PCM format collected by the audio collector at a preset sampling rate is acquired through the set-top box, and the audio data is stored in the buffer memory of the set-top box.

[0082] Wherein, the collection rate is 16K;

[0083] S2: Obtain the collected audio information from the cache, and calculate the average decibel value corresponding to the audio information within a preset time;

[008...

Embodiment 3

[0095] Take the expression form of the song automatically switching to the original accompaniment when the user orders a song in the KTV box as an example, as follows:

[0096] 1) The user clicks on the title of the song on the touch screen of the private room to order a song, activates the function of supporting singing, and activates the singing mode.

[0097] 2) Use Pinyin to search for songs, select a song, and click to play.

[0098] 3) Play songs on the TV.

[0099] 4) When the system judges that the user is neither singing nor audio input, it will automatically switch to the original singing mode.

[0100] 5) When the user sings, the system judges that there is audio input, then switches back to the accompaniment mode and turns off the original singing.

Abstract

The invention provides a method and a system for Karaoke intelligent singing guidance based on audio information. The method comprises: receiving audio information collected by an audio collector in real time and storing the audio information in a buffer memory; acquiring the collected audio information from the buffer memory, and calculating an average decibel value corresponding to the audio information in preset time; if the average decibel value is less than a preset decibel threshold, and a current play mode of a song is a vocal accompaniment mode, switching the play mode of the song to an original singer mode; if the average decibel value is larger than the preset decibel threshold and the current play mode of the song is the original singer mode, switching the play mode of the songto the vocal accompaniment mode. The method and the system solve problems that the original singer mode / vocal accompaniment mode of a song in an existing karaoke system need to be manually switched,and operation is cumbersome.

Description

technical field [0001] The invention relates to the technical field of karaoke, in particular to an audio information-based intelligent karaoke singing guide method and system. Background technique [0002] The set-top boxes currently used in the market have two modes of original singing and accompanying singing when playing songs, that is, when the song is playing the original singing, the original singing will continue to play when the user sings, and when the song is switched to the accompanying singing, the user stops singing , the song playback only has background music, and manual switching is required when the original singing is required, and the operation process is cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provides a kind of karaoke intelligent guidance method and system based on audio information, which solves the need to manually switch the original singing mode / accompany...
