Step S507: select a bar and rhythm as the next of the current sentence from the subsequent rhythm matrix
Rhythm obtains the second number of words of next rhythm.
It should be noted that selecting a beat section from the subsequent rhythm matrix according to the remaining number of words of current sentence
Next rhythm as the current sentence is played, is specially randomly choosed according to probability every in the subsequent rhythm matrix
One bar and rhythm is used as next rhythm, can also be started according to the bar and rhythm that every probability chooses maximum probability as it
Rhythm.
Step S508: calculating the new remaining number of words of the current sentence according to the remaining number of words and second number of words,
And return to the step S503.
In the concrete realization, next rhythm is chosen, while updating remaining number of words num=num-c, c is selected
The note quantity of next rhythm, i.e., described second number of words.When new remaining number of words num is not equal to zero, illustrate the current sentence
Son then needs to continue remaining text to choose corresponding beat there is also the not set corresponding beat of text.
Further, the step S503 is returned, that is, judges whether the new remaining number of words is zero.
It should be understood that judging whether the new remaining number of words is zero, if the new remaining number of words is zero, illustrate institute
Stating all texts in current sentence has corresponding bar and rhythm.If the new remaining number of words is not zero, illustrate described current
There are segment words not to have corresponding bar and rhythm in sentence.
Further, it if the new remaining number of words is zero, executes and described judges whether the current sentence is traversal
The step of the last one sentence arrived.
It will be appreciated that illustrating that all texts have correspondence in the current sentence if the new remaining number of words is zero
Bar and rhythm, then can further judge whether the current sentence is the last one sentence traversed.If by the sentence of extraction
Son is ranked up according to the sequencing occurred in the initial lyrics text, then to the sentence of sequence according to sequencing into
Row traversal, then need to only judge the current sentence traversed in the sentence list of sequence whether there is also next sentence,
Next sentence if it does not exist then determines that the current sentence is the last one sentence traversed, otherwise the current sentence
It is not the last one sentence traversed.When the new remaining number of words is zero, illustrate that the text in the current sentence is equal
It, can be by life if sentence all in the lyrics text to be processed completes the selection of beat provided with corresponding beat
At rhythm splice produce the corresponding lyrics rhythm of the lyrics text to be processed in chronological order.
Further, it if the new remaining number of words is not zero, returns according to the remaining number of words from the default song
The step of selecting subsequent rhythm matrix in the transfer matrix set of word rhythm generation model.
It should be noted that if the new remaining number of words is not zero, then return according to the remaining number of words from described pre-
If the step of selecting subsequent rhythm matrix in the transfer matrix set of lyrics rhythm generation model, until in the current sentence
Lyrics text generates in model from preset lyrics rhythm and selects suitable bar and rhythm, until the remaining number of words is zero,
Then the text in the current sentence has selected corresponding bar and rhythm, i.e., the described sentence rhythm and one or more subsequent
A next rhythm is spliced to form the complete words rhythm of the current sentence.
In the present embodiment, if the residue number of words is not zero, according to the remaining number of words from the default lyrics rhythm
