抄録(和) Sequence-to-sequence (seq2seq) voice conversion (VC) models have great potential for electrolaryngeal (EL) speech to normal speech converison (EL2SP). However, applying seq2seq VC on EL2SP faces challenges due to the need for vast and high-quality parallel training data. On the other hand, it is difficult to conduct effective transfer learning from normal speech to EL2SP dataset, owing to the substantial differences in acoustic features between EL and normal speech domains. To address above problems, we present novel methods with the multi-stage pretraining and fine-tuning techniques. We first employ encoder adaptation training for a pretrained seq2seq model with imperfect synthetic and original EL data. Then, we incorporate both imperfect synthetic and original parallel data for VC training. The final fine-tuning of EL2SP only uses the original dataset. The experimental results demonstrate that our approach yields significant improvements in EL2SP performance.
