Vector Taylor Series (VTS) is a powerful technique for robust ASR but, in its standard form, it can only be applied to log-filter bank and MFCC features. In earlier work, we presented a generalised VTS (gVTS) that extends the applicability of VTS to...

Robust Source-Filter Separation of Speech Signal in the Phase Domain (2017)
Presentation / Conference Contribution
Loweimi, E., Barker, J., Torralba, O. S., & Hain, T. (2017). Robust Source-Filter Separation of Speech Signal in the Phase Domain. In Proc. Interspeech 2017 (414-418). https://doi.org/10.21437/interspeech.2017-210

In earlier work we proposed a framework for speech source-filter separation that employs phase-based signal processing. This paper presents a further theoretical investigation of the model and optimisations that make the filter and source representat...

Statistical normalisation of phase-based feature representation for robust speech recognition (2017)
Presentation / Conference Contribution
Loweimi, E., Barker, J., & Hain, T. (2017). Statistical normalisation of phase-based feature representation for robust speech recognition. In 2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP). https://doi.org/10.1109/

In earlier work we have proposed a source-filter decomposition of speech through phase-based processing. The decomposition leads to novel speech features that are extracted from the filter component of the phase spectrum. This paper analyses this spe...
