Embodiment 1
[0108] refer to figure 1 , which shows a flow chart of steps in Embodiment 1 of a method for synthesizing speech and music provided by an embodiment of the present invention, which may specifically include the following steps:
[0109] Step 101, obtain input voice data and background music data;
[0110] In the embodiment of the present invention, the voice data can be understood as the voice data formed by people who do not require regularity, and the voice and speed of speech can be erratic; the background music data can be understood as having a certain rhythm and regularity. Music data formed by a combination of tones. The "background music data" referred to in the embodiment of the present invention is essentially "music data". The word "background" is only used to emphasize its background as voice data synthesis, and does not mean that it has certain technical characteristics .
[0111] In a specific implementation, the voice data can be the voice data transmitted by ...
Embodiment 2
[0176] refer to Figure 4 , which shows a flow chart of steps in Embodiment 2 of a method for synthesizing speech and music provided by an embodiment of the present invention, which may specifically include the following steps:
[0177] Step 201, obtaining input voice data and background music data;
[0178] Step 202, identifying one or more single characters or words that make up the voice data from the voice data, and obtaining the pitch and duration of the one or more single characters or words;
[0179] Step 203, acquiring the pitch and duration of the background music data;
[0180] Step 204, according to the pitch and duration of the background music data, change the speed and / or transpose the pitch and duration of the one or more words or words;
[0181] Step 205, perform special effect processing on the speech data after the speed change and / or pitch shift processing, the special effect processing includes: echo special effect processing, and / or, T-Pain special effec...

Abstract
The embodiment of the invention provides a method, device and equipment for synthesizing voice and music. The method comprises the steps that input voice data and background music data are obtained; one or more words or phrases are identified in the voice data and tones and lasting time of the words or the phrases are obtained, wherein the voice data are composed of the words or the phrases; tone and lasting time of the background music data are obtained; according to the tone and the lasting time of the background music data, speed change processing and/or tone modification processing are/is conducted on the tones and the lasting time of the words or the phrases; the processed voice data and the background music data are synthesized so that a new audio file can be formed. According to the method, device and equipment for synthesizing voice and music, independent voice data and music data can be perfectly combined together, a music attribute is offered to the monotonous voice data, so that the quality of an whole voice stream is improved, and the gradually improved and changed requirements for voice and music synthesis of users are satisfied.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of speech synthesis, and in particular, relate to a method for synthesizing speech and music, an apparatus for synthesizing speech and music, and a device. Background technique [0002] With the development of electronic technology, users often have the requirement of synthesizing voice and music. Waveform splicing technology (or called waveform synthesis technology) is commonly used in the prior art. The development of waveform splicing technology is inseparable from the development of speech encoding and decoding technology, among which the development of LPC technology (linear predictive coding technology) has had a huge impact on waveform splicing technology. LPC technology is essentially a time waveform encoding technology, the purpose of which is to reduce the transmission rate of time domain signals. The advantage of the LPC technique is that it is simple and intuitive. The sy...
