In singing voice, the fundamental frequency (F0) carries not only melody, but also music style, personal expressivity and other characteristics specific to voice production mechanism. The F0 modeling is therefore critical for a natural-sounding and expressive synthesis. In addition, for artistic purposes, composers also need to have control over expressive(More)
Expressive singing voice synthesis requires an appropriate control of both prosodic and timbral aspects. While it is desirable to have an intuitive control over the expressive parameters, synthesis systems should be able to produce convincing results directly from a score. As countless interpretations of a same score are possible, the system should also(More)
Singingvoice synthesis benefits from very highquality estimation of the resonances and anti-resonances of the vocal tract filter (VTF), i.e., an amplitude spectral envelope. In the state of the art, a single frame of DFT transform is commonly used as a basis for building spectral envelopes. Even though multiple frame analysis (MFA) has already been(More)
In the state of the art, a single frame of DFT transform is commonly used as a basis for building amplitude spectral envelopes. Multiple Frame Analysis (MFA) has already been suggested for envelope estimation, but often with excessive complexity. In this paper, two MFA-based methods are presented: one simplifying an existing Least Square (LS) solution, and(More)
Improving expressiveness in singing voice synthesis systems requires to perform realistic timbre transformations, e.g. for varying voice intensity. In order to sing louder, singers tend to open their mouth more widely, which changes the vocal tract’s shape and resonances. This study shows, by means of signal analysis and simulations, that the main effect of(More)
The special session Singing Synthesis Challenge: Fill-In the Gap aims at comparative evaluation of singing synthesis systems. The task is to synthesize a new couplet for two popular songs. This paper address the methodology needed for quality assessment of singing synthesis systems and reports on a case study using 2 systems with a total of 6 different(More)
