Our system mainly draws on end-to-end neural networks. Specifically, we have an encoder-decoder based prosody prediction network to insert prosodic annotations for a given sentence. We use the spectrogram predictor from Tacotron2 as the end-toend phoneme-to-spectrogram generator, followed by the neural vocoder WaveRNN to convert predicted spectrograms to audio signals. Additionally, we involve finetuning strategics to improve the TTS performance in our work. Subjective evaluation of the synthetic audios is taken regarding naturalness, similarity, and intelligibility.

Voice conversion (VC) modifies a source speaker’s speech so that the result sounds like a target speaker. This becomes particularly difficult when source and target speakers speak different languages. In this work we focus on building a voice conversion system achieving consistent improvements in accent and intelligibility evaluations. Our voice conversion system is constituted by a bilingual phoneme recognition based speech representation module, a neural network based speech generation module and a neural vocoder. More concretely, we extract general phonation from the source speakers' speeches of different languages, and improve the sound quality by optimizing the speech synthesis module and adding a noise suppression post-process module to the vocoder. This framework ensures high intelligible and high natural speech, which is very close to human quality (MOS=4.17 rank 2 in Task 1, MOS=4.13 rank 2 in Task 2).","PeriodicalId":355114,"journal":{"name":"Joint Workshop for the Blizzard Challenge and Voice Conversion Challenge 2020","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116821091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies on NPVC based on vanilla VQVAE use a single codebook to encode the linguistic information at a fixed temporal scale. However, the linguistic structure contains different semantic levels (e.g., phoneme, sylla-ble, word) that span at various temporal scales. Therefore, the converted speech may contain unnatural pronunciations which can degrade the naturalness of speech. To tackle this problem, we propose to use the hierarchical latent embedding structure which comprises several vector quantization blocks operating at different temporal scales. When trained with a multi-speaker database, our proposed model can encode the voice characteristics into the speaker embedding vector, which can be used in one-shot learning settings. Results from objective and subjective tests indicate that our proposed model outperforms the conventional VQVAE based model in both intra-lingual and cross-lingual conversion tasks. The official results from Voice Conversion Challenge 2020 reveal that our proposed model achieved the highest naturalness performance among autoencoder based models in both tasks. Our implementation is being made available at 1 .","PeriodicalId":355114,"journal":{"name":"Joint Workshop for the Blizzard Challenge and Voice Conversion Challenge 2020","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132440004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
