• Abstract summary: Speech Enhancement-based Curation Pipeline (SECP) serves as a framework to onboard clean speech. This clean speech can then train a speech enhancement model, which can further refine the original dataset. We show through comparative mean opinion score (CMOS) based subjective tests that the highest and lowest bound of refined data is perceptually better than the original data.

• Abstract: As more speech technologies rely on a supervised deep learning approach with clean speech as the ground truth, a methodology to onboard said speech at scale is needed. However, this approach needs to minimize the dependency on human listening and annotation, only requiring a human-in-the-loop when needed. In this paper, we address this issue by outlining Speech Enhancement-based Curation Pipeline (SECP) which serves as a framework to onboard clean speech. This clean speech can then train a speech enhancement model, which can further refine the original dataset and thus close the iterative loop. By running two iterative rounds, we observe that enhanced output used as ground truth does not degrade model performance according to $\Delta_{PESQ}$, a metric used in this paper. We also show through comparative mean opinion score (CMOS) based subjective tests that the highest and lowest bound of refined data is perceptually better than the original data.

  Direct speech-to-speech translation (S2ST) is an attractive research topic with many advantages compared to cascaded S2ST. Direct S2ST suffers from the data scarcity problem because the corpora from speech of the source language to speech of the target language are very rare. We propose in this paper a Speech2S model, which is jointly pre-trained with unpaired speech and bilingual text data for direct speech-to-speech translation tasks.
