چکیده

A group delay-based excitation source analysis and design method is introduced for extension of TANDEM-STRAIGHT, a speech analysis, modification and synthesis system. This introduction makes all components of the system be based on interference-free representations. They are power spectrum, instantaneous frequency and group delay representations. This unification has potential to solve the major weak point of VOCODER architecture for high-quality speech manipulation applications.

Aperiodicity extraction and control using mixed mode excitation and group delay manipulation for a high quality speech analysis, modification and synthesis system STRAIGHT

A new control paradigm of source signals for high quality speech synthesis is introduced to handle a variety of speech quality, based on timefrequency analyses by the use of an instantaneous frequency and group delay. The proposed signal representation consists of a frequency domain aperiodicity measure and a time domain energy concentration measure to represent source attributes, which supplem...

Fast Prosody Modification using Instants of Significant Excitation

The objective of this work is to propose a fast method for prosody modification using the instants of significant excitation. The proposed method is significantly faster than the existing method based on finding the instants using group-delay and using the LP residual for incorporating the desired prosody features. This is achieved by (i) using the zero frequency filtering (ZFF) method for find...

A New Method for Time-Delay Compensation in Control Systems

In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...

Simplification and extension of non-periodic excitation source representations for high-quality speech manipulation systems

A systematic framework for non-periodic excitation source representation is proposed for high-quality speech manipulation systems such as TANDEM-STRAIGHT, which is basically a channel VOCODER. The proposed method consists of two subsystems for non-periodic components; a colored noise source and an event analyzer/generator. The colored noise source is represented by using a sigmoid model with no...

Prosodic manipulation using instants of significant excitation

This paper proposes a technique for prosodic (pitch and duration) manipulation using instants of significant excitation. Instants of significant excitation correspond to the instants of glottal closure (epochs) in voiced speech and to some random excitations like burst onset in the case of nonvoiced speech. Instants of significant excitation are computed from the average group delay of minimum ...
