NV-Bench: Benchmarking Nonverbal Vocalization Synthesis in Expressive Text-to-Speech Models
Abstract
While recent text-to-speech (TTS) systems increasingly integrate nonverbal vocalizations (NVVs), their evaluation lacks standardized metrics and reliable ground truth references. To bridge this gap, we propose NV-Bench, the first benchmark grounded in a functional taxonomy that treats NVVs as communicative acts rather than acoustic artifacts. NV-Bench comprises 1… See the full description on the dataset page: https://huggingface.co/datasets/CharlesNi/NV-Bench.
