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 ...

Robust Log-Energy Estimation and its Dynamic Change Enhancement for In-car Speech Recognition

Hervé Bourlard, Weifeng Li

The log-energy parameter, typically derived from a full-band spectrum, is a critical feature commonly used in automatic speech recognition (ASR) systems. However, log-energy is difficult to estimate reliably in the presence of background noise. In this pap ...

Monitoring Network Structure And Content Quality Of Signal Processing Articles On Wikipedia

Jayakrishnan Unnikrishnan, Tao-Chun Lee

Wikipedia has become a widely-used resource on signal processing. However, the freelance-editing model of Wikipedia makes it challenging to maintain a high content quality. We develop techniques to monitor the network structure and content quality of Signa ...

Crosslingual Tandem-SGMM: Exploiting Out-Of-Language Data for Acoustic Model and Feature Level Adaptation

Petr Motlicek, Philip Neil Garner, David Imseng

Recent studies have shown that speech recognizers may benefit from data in languages other than the target language through efficient acoustic model- or feature-level adaptation. Crosslingual Tandem-Subspace Gaussian Mixture Models (SGMM) are successfully ...

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 ...

Who Wants To Be A Millionaire? (II)

Hervé Bourlard, Petr Motlicek, Huseyn Gasimov

The developed and implemented game exploiting state-of-the-art speech processing technologies is called “Who wants to be a millionaire?”. This game simulates well-known TV-based quiz game spread in many countries. This optional project, partially made at E ...

Multi-parametric source-filter separation of speech and prosodic voice restoration

Olaf Schleusing

In this thesis, methods and models are developed and presented aiming at the estimation, restoration and transformation of the characteristics of human speech. During a first period of the thesis, a concept was developed that allows restoring prosodic voic ...

Progress report of a project in very low bit-rate speech coding

Petr Motlicek, Philip Neil Garner, Milos Cernak

Background work in various levels of speech coding is reviewed, including unconstrained coding and recognition-synthesis approaches that assume the signal is speech. A pilot project in HMM-TTS based speech coding is then described, in which a comparison wi ...

Speaker diarization of overlapping speech based on silence distribution in meeting recordings

Fabio Valente, Sree Harsha Yella

Speaker diarization of meetings can be significantly improved by overlap handling. Several previous works have explored the use of different features such as spectral, spatial and energy for overlap detection. This paper proposes a method to estimate proba ...
