AM-FM DECOMPOSITION OF SPEECH SIGNAL: APPLICATIONS FOR SPEECH PRIVACY AND DIAGNOSIS
Petr Motlicek, Hynek Hermansky, Sriram Ganapathy, Amrutha Prasad
Although current trends in speech processing consider deep learning through data-driven technologies, many potential applications exhibit lack of training or development data. Therefore, considerably light signal processing techniques are still of interest ...

2019Spectral Subspace Analysis for Automatic Assessment of Pathological Speech Intelligibility
Hervé Bourlard, Ina Kodrasi, Parvaneh Janbakhshi
Speech intelligibility is an important assessment criterion of the communicative performance of pathological speakers. To assist clinicians in their assessment, time- and cost-efficient automatic intelligibility measures offering a repeatable and reliable ...
2019Joint estimation of RETF vector and power spectral densities for speech enhancement based on alternating least squares
The multi-channel Wiener filter (MWF) is a well-known multi-microphone speech enhancement technique, aiming at improving the quality of the recorded speech signals in noisy and reverberant environments. Assuming that reverberation and ambient noise can be ...
2019Combining the SNR Spectrum with a Cochlear Model
The SNR spectrum was previously introduced as a natural consequence of using cepstral normalisa-
tion in speech recognition; it is closely related to the articulation index of Fletcher. Motivated initially
by a theoretical difficulty in frequency warping, ...
Idiap2018Predicting Group Performance in Task-Based Interaction
Catharine Regina Monika Maria Oertel Genannt Bierbach
We address the problem of automatically predicting group performance on a task, using multimodal features derived from the group conversation. These include acoustic features extracted from the speech signal, and linguistic features derived from the conver ...
ASSOC COMPUTING MACHINERY2018Characterisation of voice quality of Parkinson's disease using differential phonological posterior features
Change in voice quality (VQ) is one of the first precursors of Parkinson's disease (PD). Specifically, impacted phonation and articulation causes the patient to have a breathy, husky-semiwhisper and hoarse voice. A goal of this paper is to characterize a V ...
