Diptasree Debnath<\/div>\n
\u00a0<\/div>\n
Diptasree joined the lab (Sept 2022) as a PhD student working on\u00a0Multi-dimensional Quality Assessment of Synthesized Speech<\/b>. This research will be co-funded by SFI Insight and Xperi Corp.\u00a0In the evaluation of Text-To-Speech (TTS) systems, one of the main performance indicators is how natural the synthesized speech sounds. To measure the naturalness, auditory listening tests are performed. In these tests, participants rate the naturalness on a five-point absolute category scale. The average across all test participants then gives the naturalness MOS (mean opinion score). Although this evaluation is time-consuming and costly and there is no reliable instrumental model available. The project will explore the potential of self supervised data driven models (e.g. wav2vec) to learn speech representations that can measure the quality and naturalness of synthetic speech.<\/div>\n
\u00a0<\/div>\n
Asad Ullah\u00a0<\/div>\n
\u00a0<\/div>\n
Asad joined QxLab in September 2022 as a PhD student working on\u00a0Intermediate Speech Representations for Low Resource Speech Models<\/b>. Asad will be part of the SFI ML-Labs<\/a> cohort four. Feature extraction and intermediate speech representation are important components for speech processing tasks. \u00a0This project will adapt state-of-the-art deep learning architecture to improve the existing speech representation methods. New methods emerging from the fields of computer vision (CV) and natural language processing (NLP) will be explored for cross-domain inspiration.<\/div>\n<\/div>\n
