What is EmotiVoice
EmotiVoice is an open-source multilingual, multi-voice, and prompt-controlledtext-to-speech(TTS) system by NetEase Youdao. EmotiVoice supports English and Chinese, offers over 2,000 voices, and supports generating speech with different emotions (such as happy, sad, angry, etc.) based on prompts. EmotiVoice features emotional synthesis,voice cloningand other functions, and provides a Web interface and an OpenAI-compatible API, making it easy for users to use and developers to integrate, suitable for various scenarios such as voice assistants and audiobooks.
Main Features of EmotiVoice
- Multilingual Support: Supports both Chinese and English.
- Massive Voices: Provides over 2,000 different voices.
- Emotional Synthesis: Supports synthesizing speech containing a wide range of emotions such as happiness, excitement, sadness, anger, etc.
- Ease of Use: Provides a simple and easy-to-use Web interface and supports batch generation script interfaces.
- Voice Cloning: Supports voice cloning.
Technical Principles of EmotiVoice
- Emotion and Style Control: Based on style embeddings, descriptions of emotions or styles are embedded into the model, allowing the model to generate speech with corresponding emotions or styles according to input prompts. During training, the model is trained with speech data containing multiple emotions and styles to better understand and generate speech with different emotions and styles. When generating speech, the model performs conditional generation based on the input text and emotion/style prompts, achieving control over emotion and style.
- Multilingual and Multi-Voice Support: The model is trained with data in multiple languages to understand and generate speech in different languages. A unique embedding vector is trained for each speaker to generate speech for different speakers.
- Efficient Inference and Deployment: Quickly deploy EmotiVoice based on Docker containers, without the need to manually install and configure complex dependency environments. EmotiVoice provides an OpenAI-compatible TTS API, making it easy for users to integrate and use in existing systems. Users can perform interactive speech synthesis through the Web interface, or batch generation through script interfaces.
- Pretrained Models and Fine-Tuning: The model is pretrained on large-scale speech data to learn general speech features and patterns. Users can fine-tune the pretrained model according to their needs, for example, adjusting the speed, pitch, or emotional intensity of the speech, to generate speech that meets their requirements.
