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 ...

Talker-to-listener distance effects on the variations of the intensity and the fundamental frequency of speech
In this study we focus on the relationship between the talker-tolistener distance (TLD) and the dynamics of speech intensity and fundamental frequency. A new experiment for the ex...

Towards robust word discovery by self-similarity matrix comparison
Word discovery is the task of discovering and collecting occurrences of repeating words in the absence of prior acoustic and linguistic knowledge, or training material. The capabi...
