 ## Features
 🌍 **Chinese** supported mandarin and tested with multiple datasets: aidatatang_200zh, magicdata
 
 🤩 **PyTorch** worked for pytorch, tested in version of 1.9.0(latest in August 2021), with GPU Tesla T4 and GTX 2060
 
-🌍 **Windows + Linux** tested in both Windows OS and linux OS after fixing nits 
+🌍 **Windows + Linux** tested in both Windows OS and linux OS after fixing nits
 
 🤩 **Easy & Awesome** effect with only newly-trained synthesizer, by reusing the pretrained encoder/vocoder

 > If you get an `ERROR: Could not find a version that satisfies the requirement torch==1.9.0+cu102 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2 )` This error is probably due to a low version of python, try using 3.9 and it will install successfully
 * Install [ffmpeg](https://ffmpeg.org/download.html#get-packages).
 * Run `pip install -r requirements.txt` to install the remaining necessary packages.
+* Install webrtcvad `pip install webrtcvad-wheels`(If you need)
 > Note that we are using the pretrained encoder/vocoder but synthesizer, since the original model is incompatible with the Chinese sympols. It means the demo_cli is not working at this moment.
 ### 2. Train synthesizer with your dataset
 * Download aidatatang_200zh or SLR68 dataset and unzip: make sure you can access all .wav in *train* folder
 * Preprocess with the audios and the mel spectrograms:
 `python synthesizer_preprocess_audio.py <datasets_root>`
 Allow parameter `--dataset {dataset}` to support adatatang_200zh, magicdata

+>If it happens `the page file is too small to complete the operation`, please refer to this [video](https://www.youtube.com/watch?v=Oh6dga-Oy10&ab_channel=CodeProf) and change the virtual memory to 100G (102400), for example : When the file is placed in the D disk, the virtual memory of the D disk is changed.

 * Preprocess the embeddings:
 `python synthesizer_preprocess_embeds.py <datasets_root>/SV2TTS/synthesizer`
 
 * Train the synthesizer:
 `python synthesizer_train.py mandarin <datasets_root>/SV2TTS/synthesizer`
