Time-Varying Quasi-Closed-Phase Analysis for Accurate Formant Tracking in Speech Signals

1 code implementation31 Aug 2023 Dhananjaya Gowda, Sudarsana Reddy Kadiri, Brad Story, Paavo Alku

Formant tracking experiments with a wide variety of synthetic and natural speech signals show that the proposed TVQCP method performs better than conventional and popular formant tracking tools, such as Wavesurfer and Praat (based on dynamic programming), the KARMA algorithm (based on Kalman filtering), and DeepFormants (based on deep neural networks trained in a supervised manner).

Refining a Deep Learning-based Formant Tracker using Linear Prediction Methods

no code implementations17 Aug 2023 Paavo Alku, Sudarsana Reddy Kadiri, Dhananjaya Gowda

The results indicated that the data-driven DeepFormants trackers outperformed the conventional trackers and that the best performance was obtained by refining the formants predicted by DeepFormants using QCP-FB analysis.

Analysis and Detection of Pathological Voice using Glottal Source Features

no code implementations25 Sep 2023 Sudarsana Reddy Kadiri, Paavo Alku

From the detection experiments it was observed that the performance achieved with the studied glottal source features is comparable or better than that of conventional MFCCs and perceptual linear prediction (PLP) features.
