Evaluating Sampling-based Filler Insertion with Spontaneous TTS (2022.lrec-1)
Copied to clipboard
| Challenge: | Injecting fillers into spoken dialogue systems has a rich history of study . ambiguity of filler occurrence and inter-speaker difference make modeling and evaluation difficult. |
| Approach: | They propose an objective score for filler insertion using sampling-based sampling . they build three models trained on two single-speaker spontaneous corpora and evaluate them with FPP and perceptual tests. |
| Outcome: | The proposed model is useful in analysis but does not correlate well with perceptual MOS. |
The Role of Creaky Voice in Turn Taking and the Perception of Speaker Stance: Experiments Using Controllable TTS (2024.lrec-main)
Copied to clipboard
| Challenge: | Recent advances in spontaneous text-to-speech (TTS) have enabled the realistic generation of creaky voice, a voice quality known for its diverse pragmatic and paralinguistic functions. |
| Approach: | They used a creaky voice detection tool and a neural TTS engine to control creaky phonation in a spontaneous speech corpus to investigate the effect of creaky voices on perceived certainty, valence, sarcasm, and turn finality. |
| Outcome: | The proposed model enables the realistic synthesis of creaky voice in perceptual tests without formal training. |
