Embodiment Construction

[0024] The following detailed description is exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, the intention is not to be limited by any theory presented in the preceding description of the background of the invention and the following detailed description. It is an object of the present invention to provide a template-based speaking-to-singing (STS) conversion system in which a template singing voice from an individual, such as a professional singer, is used to synthesize a singing voice from another person's speaking voice.

[0025] Unlike the conventional technique of estimating an acoustic feature for synthesizing a singing voice based on a song score, the operation according to the present embodiment generates a singing voice only from a voice reading lyrics. Using the sound quality of the speaker while employing the melody of a professional voice, the user's speaking voice can be transformed into sin...

Abstract

A system and method for speech-to-singing synthesis is provided. The method includes deriving characteristics of a singing voice for a first individual and modifying vocal characteristics of a voice for a second individual in response to the characteristics of the singing voice of the first individual to generate a synthesized singing voice for the second individual. In one embodiment, the method includes deriving a template of first speech characteristics and first singing characteristics in response to a first individual's speaking voice and singing voice and extracting second speech characteristics from a second individual's speaking voice, then modifying the second speech characteristics in accordance with the template to generate the second individual's approximated singing voice and aligning acoustic features of the second individual's approximated singing voice in response to the first speech characteristics, the first singing characteristics and the second speech characteristics to generate the second individual's synthesized singing voice.

Description

[0001] priority statement [0002] The present application claims priority from Singapore Patent Application No. 201201581-4 filed on 6 March 2012. technical field [0003] The present invention relates generally to voice synthesis, and more particularly to systems and methods for template-based personalized singing synthesis. technical background [0004] From the use of linear predictive coding (LPC) in computers to synthesize singing voices in the 1960s to today's synthesis techniques, the direct impact of computer-based music technology on the entertainment industry has grown. For example, singing voice synthesis techniques, such as synthesizing singing voices from spoken voices of lyrics, have many applications in the entertainment industry. An advantage of vocal synthesis through speaking-to-singing conversion is that it tends to preserve the timbre of the voice. Therefore, it is easy to realize high singing voice quality and to generate individualized singing. One ...
