Abstract

<B>SINTETIZADOR DE FALA TENDO BASE DE DADOS DE ELEMENTO ACúSTICO<D> Um método de síntese de fala emprega uma base de dados de elemento acústico que é estabelecida a partir de seq³ências fonéticas ocorridas em um intervalo de um sinal de fala. ao estabelecer a base de dados, trajetórias são determinadas (220) para cada uma das seq³ências fonéticas contendo um segmento fonético que corresponde a um fonema particular (210). Uma região de tolerância é então identificada baseada em uma concentração de trajetórias que correspondem às seq³ências de fonemas diferentes (230). Os elementos acústicos para a base de dados (260) são formados por porções das seq³ências fonéticas ao identificar pontos de corte (250) nas seq³ências fonéticas que correspondem aos pontos de tempo ao longo das trajetórias respectivas próximas à região de tolerância (240). Desta maneira, é possível concatenar os elementos acústicos tendo um fonema de junção comum, de modo que descontinuidades perceptíveis nos fonemas de junção sejam minimizadas. Métodos computacionalmente simples e rápidos para determinar a região de tolerância são também expostos.
