What is Qwen-TTS
Qwen-TTS is launched by Alibaba Tongyispeech synthesisModel, featuring naturalness, stability, and speed. The model can output high-quality audio based on text and voice parameter, supporting Chinese, English, and dialect synthesis, such as Beijing dialect, Shanghai dialect, Sichuan dialect, etc. The model is trained on large-scale corpora, and its generation quality is close to human level. Qwen-TTS supports streaming output, with a short time to first packet, and is suitable for various scenarios. It supports users to integrate via Python, Java, and other languages, and implement speech synthesis through API calls to meet diverse needs.

Technical Principles of Qwen-TTS
- Deep learning-based acoustic model: Qwen-TTS uses deep neural networks (such as Transformer, Tacotron, etc.) to model the mapping relationship between text and speech. Neural networks can learn the complex mapping between text features and speech features, generating natural and fluent speech. Based on the attention mechanism, the model better aligns text and speech features, making the generated speech more natural in prosody, pauses, and tone. The attention mechanism enables the model to dynamically focus on relevant parts of the text when generating each speech unit, improving the quality of synthesized speech.
- Large-scale corpus training: Qwen-TTS is trained on a large-scale corpus of more than 3 million hours. The corpus includes multiple languages, dialects, speaking styles, and emotional expressions. The rich corpus enables the model to learn speech features under different languages and styles, improving the diversity and naturalness of synthesized speech. During training, data augmentation techniques (such as adding noise, changing speech rate, adjusting pitch, etc.) improve the model's robustness and adaptability.
- Voice modeling and personalization: Based on voice embedding technology, Qwen-TTS incorporates different voice features into the speech synthesis process. Each voice has its own unique feature vector, and the model combines these feature vectors when generating speech to achieve synthesis of different voices. Users can choose different voices as needed and fine-tune the voice to meet specific personalized needs.
