Text en actes de congrés
Accés restringit per política de l'editorialAcoustic source localization and sound recognition are common acoustic scene analysis tasks that are usually considered separately. In this paper, a new source localization technique is proposed that works jointly with an ... -
Sound-to-imagination: an exploratory study on cross-modal translation using diverse audiovisual data
Areias Fanzeres, Leonardo; Nadeu Camprubí, Climent (Multidisciplinary Digital Publishing Institute, 2023-09-29)
Article
Accés obertThe motivation of our research is to explore the possibilities of automatic sound-to-image (S2I) translation for enabling a human receiver to visually infer occurrences of sound-related events. We expect the computer to ... -
Source ambiguity resolution of overlapped sounds in a multi-microphone room environment
Chakraborty, Rupayan; Nadeu Camprubí, Climent; Butko, Taras (2014-04)
Article
Accés obertWhen several acoustic sources are simultaneously active in a meeting room scenario, and both the position of the sources and the identity of the time-overlapped sound classes have been estimated, the problem of assigning ... -
Speaker identification in noisy conditions using linear prediction of one-sided autocorrelation sequence

Speaker verification on the polycost database using frequency filtered spectral energies
Hernando Pericás, Francisco Javier; Nadeu Camprubí, Climent (1998)
Text en actes de congrés
Accés obertThe spectral parameters that result from filtering the frequency sequence of log mel-scaled filter-bank energies with a first or second order FIR filter have proved to be competitive for speech recognition. Recently, the ... -
Specific distance for feature selection in speech recognition
