In earlier work we studied the effect of statistical normalisation for phase-based features and observed it leads to a significant robustness improvement. This paper explores the extension of the generalised Vector Taylor Series (gVTS) noise compensa... Read More about Exploring the Use of Group Delay for Generalised VTS Based Noise Compensation.

On the Usefulness of the Speech Phase Spectrum for Pitch Extraction (2018)
Presentation / Conference Contribution
Loweimi, E., Barker, J., & Hain, T. (2018). On the Usefulness of the Speech Phase Spectrum for Pitch Extraction. In Proc. Interspeech 2018 (696-700). https://doi.org/10.21437/interspeech.2018-1062

Most frequency domain techniques for pitch extraction such as cepstrum, harmonic product spectrum (HPS) and summation residual harmonics (SRH) operate on the magnitude spectrum and turn it into a function in which the fundamental frequency emerges as...
