Abstract

DETECÇÃO DE ATIVIDADE DE VOZ DE USUÁRIO USANDO CLASSIFICADOR DINÂMICO. Um dispositivo inclui uma memória configurada para armazenar instruções e um ou mais processadores configurados para executar as instruções. O um ou mais processadores são configurados para executar as instruções para receber dados de áudio incluindo primeiros dados de áudio correspondentes a uma primeira emissão de um primeiro microfone e segundos dados de áudio correspondentes a uma segunda emissão de um segundo microfone. O um ou mais processadores também são configurados para executar as instruções para fornecer os dados de áudio a um classificador dinâmico. O classificador dinâmico é configurado para gerar uma emissão de classificação correspondente aos dados de áudio. O um ou mais processadores são adicionalmente configurados para executar as instruções para determinar, pelo menos parcialmente com base na emissão de classificação, se os dados de áudio correspondem ou não à atividade de voz de usuário.
