Article
Accés restringit per política de l'editorialAutomatic speech recognition in a room with distant microphones is strongly affected by noise and reverberation. In scenarios where the speech signal is captured by several arbitrarily located microphones the degree of ... -
Channel selection using N-best hypothesis for multi-microphone ASR
Wolf, Martin; Nadeu Camprubí, Climent (2013)
Text en actes de congrés
Accés restringit per política de l'editorialIf speech is captured by several arbitrarily-located microphones in a room, the degree of distortion by noise and reverberation may vary strongly from one channel to another. Channel selection for automatic speech recognition ... -
Classification of acoustic events using SVM-based clustering schemes
Temko, Andrey A.; Nadeu Camprubí, Climent (2006)
Article
Accés obertAcoustic events produced in controlled environments may carry information useful for perceptually aware interfaces. In this paper we focus on the problem of classifying 16 types of meeting-room acoustic events. First of ... -
Comparison of time & frequency filtering and cepstral-time matrix approaches in ASR
Macho, D; Nadeu Camprubí, Climent; Jancovic, P; Rozinaj, G; Hernando Pericás, Francisco Javier (1999)
Text en actes de congrés
Accés obertIn current speech recognition systems, speech is represented by a 2-D sequence of parameters that model the temporal evolution of the spectral envelope of speech. Linear transformation or filtering along both time and ... -
