Geometric multichannel common signal separation with application to music and effects extraction from film soundtracks
We address the task of separation of music and effects from dialogs in film or television soundtracks. This is of interest for film studios wanting to release films in new, pre...

Amplitude modulation spectrogram based features for robust speech recognition in noisy and reverberant environments
In this contribution we present a feature extraction method that relies on the modulation-spectral analysis of amplitude fluctuations within sub-bands of the acoustic spectrum by ...

A novel fast canonical-signed-digit conversion technique for multiplication
Abstract—Fast multiplication can be achieved by using canonical signed digit (CSD) to speed-up computations. Conversion to CSD is needed when the multiplier is not known a priori...

Tracking changes in continuous emotion states using body language and prosodic cues
Human expressive interactions are characterized by an ongoing unfolding of verbal and nonverbal cues. Such cues convey the interlocutor’s emotional state which is continuous and...

Continuous F0 in the source-excitation generation for HMM-based TTS: Do we need voiced/unvoiced classification?
Most HMM-based TTS systems use a hard voiced/unvoiced classification to produce a discontinuous F0 signal which is used for the generation of the source-excitation. When a mixed ...
