rtvc/CHANGELOG.md

## What's new
**2022.05.19：** We calculated GE2E loss in encoder with CUDA rather than originally-configured CPU. It speeds up the encoder training speed.<br>
**2022.07.15：** We added Loss animation plot for synthesizer and vocoder.<br>
**2022.07.19：** We added response time and Griffin-Lim vocoder results for demo_toolbox.<br>
**2022.07.29：** We added model validation for encoder, synthesizer and vocoder.<br>
**2022.08.02：** We added voxceleb train and dev data for encoder. We added [noisereduce](https://github.com/timsainb/noisereduce) denoiser for the output wav from vocoder.<br>
**2022.08.06：** We split the long text into short sentences using spacy for input of synthesizer. Make sure to install spaCy model en_core_web_sm by 
`python -m spacy download en_core_web_sm`<br>
**2022.09.02：** We set prop_decrease=0.6 for male and 0.9 for female in noisereduce function.(输出滤波，男女声使用不同的滤波参数)<br>
**2022.09.26：** We added speed adjustment(声音变速) for output audios using praat, install parselmouth using pip: `pip install praat-parselmouth`<br>
**2022.10.10：** We added voice filter functioning(声音美颜) for input audios, the weight ratio of the input audio embed and the standard audio embed is 7: 3. <br>
**2022.10.25：** We set small values(<0.06) to zeros in embed.(对嵌入向量较小值置零)<br>
**2022.10.26：** The split frequency for input audio is 170Hz. The split frequency for output noise reduce is 165Hz.<br>
**2022.12.01：** merge the single sentences to input.<br>
**2022.12.31：** added speaker embeddings dimension reduction visualzation results.<br>
**2023.01.01：** did more text preprocessing and text cleaning for TTS text input.<br>
**2023.02.27：** preprocessed ascii chars and abbreviations.<br>
**2023.06.09：** We added VCTK train and dev data for synthesizer. We also combine a [deep learning denoiser](https://github.com/facebookresearch/denoiser) with the [noisereduce](https://github.com/timsainb/noisereduce) denoiser for optimized output wav quality.<br>
