Qwen-TTS - A speech synthesis model launched by Alitongyi

Qwen-TTS is a speech synthesis model developed by Alibaba Tongyi, characterized by its natural, stable, and fast performance. The model can output high-quality audio based on text and timbre parameters, supporting the synthesis of Chinese, English, and dialects such as Beijing Mandarin, Shanghainese, etc.

What is Qwen-TTS?

Qwen-TTS is a speech synthesis model launched by Alibaba Tongyi, characterized by its naturalness, stability, and speed. The model can output high-quality audio based on text and timbre parameters, supporting the synthesis of Chinese, English, and dialects such as Beijing Mandarin, Shanghainese, and Sichuanese. Trained on a large-scale corpus, the model achieves near-human-level performance. Qwen-TTS supports streaming output, has a short initial packet generation time, and is suitable for various scenarios. Users can integrate the model using languages such as Python and Java, implementing speech synthesis through API calls to meet diverse needs.

Main functions of Qwen-TTS

  • Multilingual supportIt supports Chinese, English, mixed Chinese and English, and multiple dialects (such as Beijing dialect, Shanghai dialect, and Sichuan dialect) to meet the needs of different scenarios.
  • Rich timbreOffers a variety of voice options, including voices of different genders and styles, such as Chelisie, Cherry, Ethan, Serena, Dylan, Jada, Sunny, etc., to meet individual needs.
  • High-quality audioSupports 24kHz sampling rate WAV format audio output to ensure audio quality.
  • Streaming outputIt supports audio streaming output, allowing simultaneous reception and playback, making it suitable for real-time voice interaction scenarios.
  • Multiple access methodsIt supports multiple access methods such as Python, Java, and HTTP, making it convenient for developers to integrate.
  • API callsIt provides a simple and easy-to-use API interface to help developers quickly implement speech synthesis functions.

Qwen-TTS Technical Principles

  • Deep learning-based acoustic modelsQwen-TTS uses deep neural networks (such as Transformer and Tacotron) 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 an attention mechanism, the model better aligns text and speech features, making the generated speech more natural in terms of rhythm, pauses, and intonation. The attention mechanism allows the model to dynamically focus on relevant parts of the text when generating each speech unit, improving the quality of the synthesized speech.
  • Large-scale corpus trainingQwen-TTS is trained on a massive corpus of over 3 million hours, encompassing multiple languages, dialects, speaking styles, and emotional expressions. This rich corpus allows the model to learn speech features across different languages and styles, improving the diversity and naturalness of the synthesized speech. During training, data augmentation techniques (such as adding noise, changing speech rate, and adjusting pitch) are used to enhance the model's robustness and adaptability.
  • Sound modeling and personalizationBased on timbre embedding technology, Qwen-TTS integrates different timbre features into the speech synthesis process. Each timbre has its unique feature vector, and the model combines these feature vectors when generating speech to achieve the synthesis of different timbres. Users can select different timbres according to their needs and fine-tune the timbre to meet specific personalized requirements.
