Unet-TTS: Improving Unseen Speaker and Style Transfer in One-shot Voice Cloning

English | 中文

❗ Now we provide inferencing code and pre-training models. You could generate any text sounds you want.

⭐ The model training only uses the corpus of neutral emotion, and does not use any strongly emotional speech.

⭐ There are still great challenges in out-of-domain style transfer. Limited by the training corpus, it is difficult for the speaker-embedding or unsupervised style learning (like GST) methods to imitate the unseen data.

⭐ With the help of Unet network and AdaIN layer, our proposed algorithm has powerful speaker and style transfer capabilities.

😄 The authors are preparing simple, clear, and well-documented training process of Unet-TTS based on Aishell3. It contains:

• MFA-based duration alignment
• Multi-speaker TTS with speaker_embedding-Instance-Normalization, and this model provides pre-training Content Encoder.
• Unet-TTS training
• One-shot Voice cloning inference
• C++ inference

Stay tuned!

Tts_handel = UnetTTS(models_and_params, text2id_mapper, feats_yaml)

#text: input text

#dur_stat: phoneme duration statistis to contraol speed rate
syn_audio, _, _ = Tts_handel.one_shot_TTS(text, src_audio, dur_stat)
