• Abstract: In this paper, we pose the current state-of-the-art voice conversion (VC) systems as two-encoder-one-decoder models. After comparing these models, we combine the best features and propose Assem-VC, a new state-of-the-art any-to-many non-parallel VC system. This paper also introduces the GTA finetuning in VC, which significantly improves the quality and the speaker similarity of the outputs. Assem-VC outperforms the previous state-of-the-art approaches in both the naturalness and the speaker similarity on the VCTK dataset. As an objective result, the degree of speaker disentanglement of features such as phonetic posteriorgrams (PPG) is also explored. Our investigation indicates that many-to-many VC results are no longer distinct from human speech and similar quality can be achieved with any-to-many models.

  Voice Conversion (VC) is a technique that aims to transform the non-linguistic information of a source utterance to change the perceived identity of the speaker. We propose Voicy, a new VC framework particularly tailored for noisy speech. Our method, which is inspired by the de-noising auto-encoders framework, is comprised of four encoders (speaker, content, phonetic and acoustic-ASR) and one decoder.

  This paper proposes an any-to-many location-relative, sequence-to-sequence (seq2seq), non-parallel voice conversion approach. In this approach, we combine a bottle-neck feature extractor (BNE) with a seq2seq synthesis module. Objective and subjective evaluations show that the proposed any-to-many approach has superior voice conversion performance in terms of both naturalness and speaker similarity.
