Automatic speech recognition in cocktail-party situations : a specific training for separated speech

Martí Guerola, Amparo; Cobos Serrano, Máximo; López Monfort, José Javier (Acoustical Society of America, 2012-02)

Automatic speech recognition (ASR) refers to the task of extracting a transcription of the linguistic content of an acoustical speech signal automatically. Despite several decades of research in this important area of ...
Improvements on automatic speech segmentation at the phonetic level

Gómez Adrian, Jon Ander; Calvo Lance, Marcos (Springer Verlag (Germany), 2011)

In this paper, we present some recent improvements in our automatic speech segmentation system, which only needs the speech signal and the phonetic sequence of each sentence of a corpus to be trained. It estimates a GMM ...
Two-microphone multi-speaker localization based on a Laplacian Mixture Model

Cobos Serrano, Máximo; López Monfort, José Javier; Martinez Perez, David (Elsevier, 2011-01)

A method for multiple speaker localization using a two-microphone array is presented. Based on the disjointness property of speech signals in the time-frequency (TF) domain, the proposed approach models the distribution ...
