Formant-Based Audio Synthesis Using Nonlinear Distortion

by Miller Puckette , 1995
"... An audio synthesis technique ("Phase Aligned Formant synthesis") is presented which is aimed at real-time musical applications. A desired sound is specified in terms of one or several time-varying formants, each with specified center frequencies, bandwidths, and amplitudes. The sound produ ..."

Phase bashing for sample-based formant synthesis

by Miller Puckette - International Computer Music Association , 2005
"... Many techniques have been proposed for synthesizing the sung or spoken voice; they generally fall into two classes. First, the purely synthetic techniques (FM, FOF, PAF,...) make sounds with specified formant frequencies, bandwidths, and amplitudes. Second, the sample-based methods (LPC, Vocoders, P ..."

Transformation of formants for voice conversion using artificial neural networks

by M. Narendranath, Hema A. Murthy, S. Rajendran, B. Yegnanarayana - Speech Communication , 1995
"... In this paper we propose a scheme for developing a voice conversion system that converts the speech signal uttered by a source speaker to a speech signal having the voice characteristics of the target speaker. In particular, we address the issue of transformation of the vocal tract system features f ..."

from one speaker to another. Formants are used to represent the vocal tract system features and a formant vocoder is used for synthesis. The scheme consists of a formant analysis phase, followed by a learning phase in which the implicit formant transformation is captured by a neural network

Formant Tracking Using Segmental Phonemic Information

by Minkyu Lee, Jan Van Santen, Bernd Möbius, Joseph Olive - in Proc. Eur. Conf. Speech Communication and Technology (Eurospeech , 1999
"... A new formant tracking algorithm using phoneme dependent nominal formant values is tested. The algorithm consists of three phases: (1) analysis, (2) segmentation, and (3) formant tracking. In the analysis phase, formant candidates are obtained by solving for the roots of the linear prediction polyno ..."

polynomial. In the segmentation phase, the input text is converted into a sequence of phonemic symbols. Then the sequence is time aligned with the speech utterance. Finally, a set of formant candidates that are close to the nominal formant estimates while satisfying the continuity constraints are chosen

Formant measurement errors: Preliminary results from synthetic speech

by Philip Harrison
"... This presentation introduces the preliminary results from the latest phase of work on the variability of formant measurements. The initial study (Harrison, 2004) and subsequent IAFPA conference presentations (Harrison, 2005 & 2006) examined the magnitude of the variation in formant measurements ..."

VOICE SOURCE PARAMETERS ESTIMATION BY FITTING THE GLOTTAL FORMANT AND THE INVERSE FILTERING OPEN PHASE

by Thomas Drugman, Thomas Dubuisson, Alexis Moinet, Thierry Dutoit
"... This paper presents two approaches to the problem of extracting the parameters of the LF source model directly from the speech waveform. The first approach relies on the glottal formant estimated from the anticausal contribution of speech. Indeed the ZZT technique has recently shown its ability to d ..."

Modelling Voiceless Speech Segments by Means of an Additive Procedure Based on the Computation of Formant Sinusoids

by Ingo Hertrich, Hermann Ackermann
"... A previously developed vowel synthesis algorithm implements formants as sinusoids, amplitude- and phase-modulated by the fundamental frequency (Hertrich and Ackermann, 1999, Journal of the Acoustical Society of America, 106, 2988-2990). The present study extends this approach to the modelling of the ..."
