Voice transformation (VT) aims to change one or more aspects of a speech signal while
preserving linguistic information. A subset of VT, Voice conversion (VC) specifically aims to …

The great majority of current voice technology applications rely on acoustic features, such as
the widely used MFCC or LP parameters, which characterize the vocal tract response …

Vocoders received renewed attention recently as basic components in speech synthesis
applications such as voice transformation, voice conversion and statistical parametric …

The modeling of speech production often relies on a source-filter approach. Although
methods parameterizing the filter have nowadays reached a certain maturity, there is still a …

The synthesized voice has become an ever present aspect of daily life. Heard through our
smart-devices and from public announcements, engineers continue in an endeavour to …

In current methods for voice transformation and speech synthesis, the vocal tract filter is
usually assumed to be excited by a flat amplitude spectrum. In this article, we present a …

Recently developed speech technology platforms, such as statistical speech synthesis and
voice transformation systems, facilitate the modification of voice characteristics. To fully …

We propose a fast speech analysis method which simultaneously performs high-resolution
voiced/unvoiced detection (VUD) and accurate estimation of glottal closure and glottal …

Recently, a glottal vocoder has been integrated in the IBM concatenative TTS system and
certain configurable global voice transformations were defined in the vocoder parameter …

Emotional speech synthesis is an important part of the puzzle on the long way to humanlike
artificial human-machine interaction. On the way, lots of stations like emotional audio …
