Integration of audiovisual sensors and technologies in a smart room
Neumann, J; Casas Pla, Josep Ramon; Macho Ciena, Dusan; Ruiz Hidalgo, Javier (2009-01)
Article
Accés obertAt the Technical University of Catalonia (UPC), a smart room has been equipped with 85 microphones and 8 cameras. This paper describes the setup of the sensors, gives an overview of the underlying hardware and software ... -
On the interaction between time and frequency filtering of speech parameters
Macho Ciena, Dusan; Nadeu Camprubí, Climent (Robert H. Mannel and Jordi Robert-Ribes, 1998)
Text en actes de congrés
Accés obertOne of the great today's challenges in speech recognition is to ensure the robustness of the used speech representation. Usually, the recognition rate is strongly reduced when the speech is corrupted, e.g. by convolutional ... -
Use of voicing information to improve the robustness of the spectral parameter set
Macho Ciena, Dusan; Nadeu Camprubí, Climent (ICSLP, 2000)
Text en actes de congrés
Accés obertSpeech recognition systems that operate in real world environments have to be robust against additive noises. In this work, a technique that uses a voicing-dependent exponent in the computation of the filter-bank parameters ...
