Phonetic Error Analysis Beyond Phone Error Rate (2023)
Journal Article
Loweimi, E., Carmantini, A., Bell, P., Renals, S., & Cvetkovic, Z. (2023). Phonetic Error Analysis Beyond Phone Error Rate. IEEE/ACM Transactions on Audio, Speech and Language Processing, 31, 3346-3361. https://doi.org/10.1109/taslp.2023.3313417

In this article, we analyse the performance of the TIMIT-based phone recognition systems beyond the overall phone error rate (PER) metric. We consider three broad phonetic classes (BPCs): {affricate, diphthong, fricative, nasal, plosive, semi-vowel,... Read More about Phonetic Error Analysis Beyond Phone Error Rate.

Multi-Stream Acoustic Modelling Using Raw Real and Imaginary Parts of the Fourier Transform (2023)
Journal Article
Loweimi, E., Yue, Z., Bell, P., Renals, S., & Cvetkovic, Z. (2023). Multi-Stream Acoustic Modelling Using Raw Real and Imaginary Parts of the Fourier Transform. IEEE/ACM Transactions on Audio, Speech and Language Processing, 31, 876-890. https://doi.org/1

In this paper, we investigate multi-stream acoustic modelling using the raw real and imaginary parts of the Fourier transform of speech signals. Using the raw magnitude spectrum, or features derived from it, as a proxy for the real and imaginary part...

Acoustic Modelling From Raw Source and Filter Components for Dysarthric Speech Recognition (2022)
Journal Article
Yue, Z., Loweimi, E., Christensen, H., Barker, J., & Cvetkovic, Z. (2022). Acoustic Modelling From Raw Source and Filter Components for Dysarthric Speech Recognition. IEEE/ACM Transactions on Audio, Speech and Language Processing, 30, 2968-2980. https://d

Acoustic modelling for automatic dysarthric speech recognition (ADSR) is a challenging task. Data deficiency is a major problem and substantial differences between typical and dysarthric speech complicate the transfer learning. In this paper, we aim...
