+features:
+
+1、input 5s vocal, zero shot TTS
+
+2、1min training dataset, fine tune (few shot TTS. The TTS model trained using few-shot techniques exhibits significantly better similarity and realism in the speaker's voice compared to zero-shot.)
+
+3、Cross lingual (inference another language that is different from the training dataset language), now support English, Japanese and Chinese
+
+4、This WebUI integrates tools such as voice accompaniment separation, automatic segmentation of training sets, Chinese ASR, text labeling, etc., to help beginners quickly create their own training datasets and GPT/SoVITS models.
