“…However, the research on whispered speech is not yet mature at home and abroad, and there is no large-scale and relatively standardized whispered speech dataset, which severely limits the research on WSR. In [1], a cross-modal speaker verification experiment was conducted by combining the fractional calibration and embedding compensation methods for vocal modes with an x-vector-based speaker verification system, which shows that further exploitation of advanced knowledge of speaker recognition technology is essential.…”

Whisper speaker recognition (WSR) has received extensive attention from researchers in recent years, and it plays an important role in medical, judicial, and other fields. Among them, the establishment of a whisper dataset is very important for the study of WSR. However, the existing whisper dataset suffers from the problems of a small number of speakers, short speech duration, and lack of neutral speech with the same-text as the whispered speech in the same dataset. To address this issue, we present Whisper40, a multi-person Chinese WSR dataset containing same-text neutral speech spanning around 655.90 min sourced from volunteers. In addition, we use the current state-of-the-art speaker recognition model to build a WSR baseline system and combine the idea of transfer learning for pre-training the speaker recognition model using neutral speech datasets and transfer the empirical knowledge of specific network layers to the WSR system. The Whisper40 and CHAINs datasets are then used to fine-tune the model with transferred specific layers. The experimental results show that the Whisper40 dataset is practical, and the time delay neural network (TDNN) model performs well in both the same/cross-scene experiments. The equal error rate (EER) of Chinese WSR after transfer learning is reduced by 27.62% in comparison.

“…Whisper, as an informal form of communication, has received much attention from researchers in recent years [1,2]. Conveying information by speaking in a low voice can avoid being heard by others, and this form of communication is often used in situations where confidentiality is required or to avoid disturbing others.…”
