One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...

Although speech recognition technology and voice synthesis systems have become readily available, recognition accuracy remain a serious problem in the design and implementation of voice-based user interfaces. Error correction becomes particularly difficult on mobile devices due to the limited system resources and constrained input methods. This research is aimed to investigate users’ acceptance...

Linguistic control factors such as word stress and phrasefinality affect not only duration and pitch, but also spectral structure and spectral dynamics. We propose methods for predicting and synthesizing prosodic effects on spectral balance: (i) A new multi-dimensional measure of spectral balance, in which energy is measured in five ”formant frequency range” bands. (ii) Statistical methods for ...

The Multiphonia Corpus consists of audio-video classroom recordings comparing two methods of phonetic correction (the ‘traditional’ articulatory method, and the Verbo-Tonal Method) This database was created not only to remedy the crucial lack of information and pedagogical resources on teaching pronunciation but also to test the benefit of VTM on Second Language pronunciation. The VTM method em...

This paper introduces a framework for parametric speech modeling that can be used in various speech applications such as text-to-speech synthesis, voice conversion etc. In order to reduce impact of pitch variations the harmonic analysis is done in the warped time scale that is aligned with instantaneous pitch values. It is assumed that each harmonic has its own periodic excitation source that e...
