Problems solved by technology

The main disadvantage of the former is that there are problems of over-fitting or under-fitting, which are characterized by weak sound quality and a large gap between the timbre and the target timbre; while the latter can make the converted voice more in line with the target timbre, but there are gaps in splicing. fluency

Abstract

The invention discloses a tone quality transition method; the method can search coupled voices from preset source-object phoneme characteristic unit pairs according to processed voice phonemes, and transiting the coupled voice; the method comprises the following steps: extracting characteristics of each voice frame of the processed voice; calculating each voice frame belonging phoneme of the processed voice, and takes continuous frames in the same phoneme as a phoneme set; splitting one phoneme set into one or more phoneme units with the first frame length according to a sequence, wherein adjacent phoneme units mutually overlap at a second frame length; splicing characteristics of each voice frame so as to obtain the characteristic of the corresponding phoneme unit; selecting the object phoneme characteristic unit with the minimum cost from the source-object phoneme characteristic unit pairs according to the phonemes and characteristics of all phoneme units, and taking the object phoneme characteristic unit as the optimal phoneme characteristic unit; splicing time domains of a plurality of the optimal phoneme characteristic units corresponding to the plurality of phoneme units, thus obtaining the voice with the transited tone quality. The invention also discloses corresponding calculation equipment.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a tone color conversion method and a computing device. Background technique [0002] In the dubbing of existing movies or TV dramas, the actors need to record the voice according to the lines of the script of the movie or TV drama. The price is high, which is very uneconomical for producers or actors. [0003] Most of the existing speech synthesis technologies can only synthesize the voice of a fixed person; some other speech synthesis technologies can synthesize the voice of the required speaker, but the amount of calculation is very large and the running time is long, so it cannot be used in practice. [0004] In real life, people often show great interest in some applications such as the conversion of male and female timbres. Therefore, there is a need for a method capable of converting a user's voice into a voice with another timbre. [0005] Existing timbre conve...
