Síntese articulatória: uma introdução
Teixeira, António; Silva, Luís Nuno; Vaz, FranciscoIn this paper we present an overview of articulatory synthesis, covering: history, usual approaches, different models for the main blocks of an articulatory synthesizer, how to obtain parameters for the models. Models adopted for the articulatory synthesizer in development by the authors for Portuguese, named SAP, are described in some detail.; Neste artigo apresenta-se uma visão geral acerca da síntese ar...
An object oriented articulatory synthesizer for Windows
Silva, Luís Nuno; Teixeira, António; Vaz, FranciscoThe main motivation for this work was the production of speech synthesis with near natural quality using a modular application with a user-friendly interface. One of the most promising methods is the use of articulatorysynthesis, which is a technique based on direct modeling ofthe human speech production process. A modular application will allow the integration of several models, improved and new, in a user-fri...
Sistema de codificação de voz de alta qualidade com banco de filtros
Fernandez, Elizabeth; Silva, Luís Nuno; Rodrigues, João; Tomé, Ana Maria; Vaz, FranciscoThis paper describes a high quality speech coding system based in the ITU Recommendation G.722 “7 kHzaudio coding within 64 kbit/s”. Provides a high-level description of the recommended algorithm and a briefdiscussion about the arithmetical choices, which have been made. Some performance results are provided.; Este artigo descreve um sistema de codificação de voz de alta qualidade baseado na Recomendação G...
