Rodríguez Fonollosa, José Adrián; Schulz, Henrik (2012)
Comunicació de congrés
Accés restringit per política de l'editorialModelling varying speaking style remains a challenge to sta te of the art speech recognition and synthesis systems. Vowel a nd consonant reduction have been identified as correlative to speaking st yle variation, but ... -
Modelling the effects of spontaneous speech in speech recognition
Shulz, Henrik; Rodríguez Fonollosa, José Adrián (2013)
Text en actes de congrés
Accés obertIntrinsic variability of the speaker in spontaneous speech remains a challenge to state of the art Automatic speech recognition (ASR). While planned speech exhibits a moderate variability, the significant variability ... -
