Investigating Inter- and Intra-speaker Voice Conversion using Audiobooks (2022.lrec-1)
Copied to clipboard
| Challenge: | Audiobook readers play with their voices to emphasize some text passages, highlight discourse changes or significant events, or in order to make listening easier and entertaining. |
| Approach: | They propose to modify the narrator’s voice to fit the context of the story, such as the character who is speaking, using voice conversion. |
| Outcome: | The proposed method improves the quality of the voice conversion system and the speaker similarity. |
Paraphrase Generation Evaluation Powered by an LLM: A Semantic Metric, Not a Lexical One (2025.coling-main)
Copied to clipboard
| Challenge: | Existing measures for automatic paraphrase generation are based on lexical distances or semantic embedding alignments. |
| Approach: | They propose a measure based on a log likelihood ratio from an LLM to assess the quality of a potential paraphrase. |
| Outcome: | The proposed measure is better for sorting pairs of sentences by semantic proximity and provides an interpretable classification threshold between paraphrases and non-paraphrases. |
