Abstract

resumo aparelho para gerar um sinal de fala, e, método para gerar um sinal de fala a presente invenção refere-se a um aparelho que compreende receptores de microfone (101) que recebem sinais de microfone de uma pluralidade de microfones (103). um comparador (105) determina uma indicação de similaridade de fala indicativa de uma similaridade entre o sinal de microfone e a fala não reverberante para cada sinal de microfone. a determinação é feita em resposta a uma comparação entre uma propriedade derivada do sinal de microfone e uma propriedade de referência para fala não reverberante. em algumas modalidades, o comparador (105) determina a indicação de similaridade ar comparar as propriedades de referência das amostras de fala de um conjunto de amostras de fala não reverberante. um gerador (107) gera um sinal de fala por meio da combinação dos sinais de microfone em resposta às indicações de similaridade. em muitas modalidades, o aparelho pode ser distribuído por uma pluralidade de dispositivos, cada um contendo um microfone, e a abordagem pode determinar o microfone mais adequado para gerar o sinal de fala. 1/1
