Abstract
Whispers represent a common and secondary mechanism of communication. Nonetheless, individuals with aphonia, including those with laryngectomy, rely on whispers as their primary means of communication. Due to the substantial acoustic differences between whispered and normally phonated speech, the task of effective whispered-to-normal speech conversion (W2NSC) remains a significant challenge and has been widely discussed in the speech processing community. This study explores several enhancements to the k-nearest neighbors voice conversion (kNN-VC) model from multiple perspectives, including experiments with alternative feature extraction models, exploring fine-tuning of pre-trained models using Low-Rank Adaptation (LoRA), and the development of mapping strategies for parallel whispered and normal speech data using both KNN (pkNN-W2NSC) and multilayer perceptron (pMLP-W2NSC) approaches. Based on these experiments, a subjective evaluation using the MUSHRA test showed that the pMLP-W2NSC system achieved the highest overall performance among all evaluated configurations.
