A Hybrid Method Oriented to Concatenative Text-to-Speech Synthesis
(2003-09-01)In this paper we present a speech synthesis method for diphonebased text-to-speech systems. Its main goal is to achieve prosodic modifications that result in more natural-sounding synthetic speech. ... -
A Pitch Marks Filtering Algorithm Based on Restricted Dynamic Programming
(2006-09-17)In this paper, a generic pitch marks filtering algorithm (PMFA) is introduced in order to achieve reliable and smooth pitch marks from any input pitch tracking or marking algorithm. The proposed PMFA ... -
Asignación automática de marcas de pitch basada en programación dinámica
(Procesamiento del lenguaje natural, No. 27 (2001), 2001)En este artículo se presenta la implementación y evaluación de un sistema de generación automática de marcas de pitch, para el etiquetado de un corpus de voz. El sistema está basado en dos conceptos: ... -
Comparative Study on Feature Selection and Fusion Schemes for Emotion Recognition from Speech
(International Journal of Interactive Multimedia and Artificial Intelligence, 2012, Vol. 1, No. 6 (Setembre), 2012-09)The automatic analysis of speech to detect affective states may improve the way users interact with electronic devices. However, the analysis only at the acoustic level could be not enough to determine ... -

Evolutionary weight tuning based on diphone pairsfor unit selection speech synthesis
(2003-09-01)Unit selection text-to-speech (TTS) conversion is an ongoingresearch for the speech synthesis community. This paper isfocused on tuning the weights involved in the target and con-catenation cost metrics. ... -
GTM-URL Contribution to the INTERSPEECH 2009 Emotion Challenge
(2009-09)This paper describes our participation in the INTERSPEECH 2009 Emotion Challenge [1]. Starting from our previous experience in the use of automatic classification for the validation of an expressive ... -
Hacia una síntesis concatenativa de alta calidad para aplicaciones de conversión texto-habla
(Procesamiento del lenguaje natural, No 25 (1999), 1999)Este artículo describe nuevas líneas de investigación referentes a la síntesis concatenativa para la conversión texto-habla. La técnica TD-PSOLA supuso un salto importante en cuanto a la mejora de la ... -
HMM-based Spanish speech synthesis using CBR as F0 estimator
(2007-05)Hidden Markov Models based text-to-speech (HMM-TTS) syn thesis is a technique for generating speech from trained statisti cal models where spectrum, pitch and durations of basic speech units are modelled ... -
Linguistic and Mixed Excitation Improvements on a HMM-based speech synthesis for Castilian Spanish
(Proceedings of the 6th ISCA Workshop on Speech Synthesis, 2007-08)HiddenMarkov Models based text-to-speech(HMM-TTS)synthesis is one of the techniques for generating speech from trained statistical models where spectrum and prosody of basic speech units are modelled ... -
Local minimum generation error criterion for hybrid HMM speech synthesis
(2009-09)This paper presents an HMM-driven hybrid speech synthesis approach in which unit selection concatenative synthesis is used to improve the quality of the statistical system using a Local Minimum Generation ... -
