Syllabic Pitch Tuning for Neutral-to-Emotional Voice Conversion

Prosody plays an important role in both identification and synthesis of emotionalized speech. Prosodic features like pitch are usually estimated and altered at a segmental level based on short windows of speech (where the signal is expected to be quasi-sta ...

Ethnography of a political ritual: speeches given to new Swiss citizens by representatives of the state

Maxime Carl Felder

Our paper examines speeches given at citizenship ceremonies in Geneva (Switzerland) in order to understand what makes a foreigner a new member of a national and especially of a cantonal entity. Focusing on speeches by three ministers over an interval of 4 ...

Objective Speech Intelligibility Assessment through Comparison of Phoneme Class Conditional Probability Sequences

Hervé Bourlard, Raphaël Marc Ullmann

Assessment of speech intelligibility is important for the development of speech systems, such as telephony systems and text-to-speech (TTS) systems. Existing approaches to the automatic assessment of intelligibility in telephony typically compare a referen ...

Prosody in Swiss French Accents: Investigation using Analysis by Synthesis

Philip Neil Garner, Pierre-Edouard Jean Charles Honnet

It is very common for a language to have different dialects or accents. The different pronunciations of the same words is one of the reasons for the different accents, in the same language. Swiss French accents have similar pronunciation to standard French ...

Joint Source-Filter Optimization for Accurate Vocal Tract Estimation Using Differential Evolution

Jean-Marc Vesin, Olaf Schleusing

In this work, we present a joint source-filter optimization approach for separating voiced speech into vocal tract (VT) and voice source components. The presented method is pitch-synchronous and thereby exhibits a high robustness against vocal jitter, shim ...

A Savitzky-Golay Filtering Perspective of Dynamic Feature Computation

Mathew Magimai Doss, Chandra Sekhar Seelamantula

We address the classical problem of delta feature computation, and interpret the operation involved in terms of Savitzky-Golay (SG) filtering. Features such as the mel-frequency cepstral coefficients (MFCCs), obtained based on short-time spectra of the spe ...

Unified Framework of Feature Based Adaptation for Statistical Speech Synthesis and Recognition

Lakshmi Babu Saheer

The advent of statistical parametric speech synthesis has paved new ways to a unified framework for hidden Markov model (HMM) based text to speech synthesis (TTS) and automatic speech recognition (ASR). The techniques and advancements made in the field of ...

Source/Filter Factorial Hidden Markov Model, with Application to Pitch and Formant Tracking

Jean-Philippe Thiran

Tracking vocal tract formant frequencies (

f_p

) and estimating the fundamental frequency (

f_0

) are two tracking problems that have been tackled in many speech processing works, often independently, with applications to articulatory parameters estimation ...

Model-based Sparse Component Analysis for Multiparty Distant Speech Recognition

Afsaneh Asaei

This research takes place in the general context of improving the performance of the Distant Speech Recognition (DSR) systems, tackling the reverberation and recognition of overlap speech. Perceptual modeling indicates that sparse representation exists in ...
