Main functions

  • Text to voice : Supports multiple voice control options, such as intonation, emotion, speed, etc.

  • Multi-voice options : Provides 11 different sound models, such as alloy, ash, coral, etc.

  • Multilingual support : supports voice synthesis in multiple languages to meet the needs of global users.

  • Real-time audio stream processing : supports real-time generation and output of audio data, gradually playing, without waiting for the complete audio file.

  • Multi-format output : supports multiple output formats, such as MP3, Opus, AAC, etc., which is convenient for integration into different applications.

Technical Principles

  • Based on the GPT-4o mini model : Advanced GPT-4o mini technology is used to generate natural and smooth voice, with a maximum input character number of 2000.

  • Emotional and Style Control : By introducing additional control signals, the model can adjust the emotions and style of the voice (such as "calm", "encourage", "serious" and so on).

  • Multilingual dataset : Use multilingual datasets during the training phase, allowing the model to generate natural speech in multiple languages.

  • Real-time audio streaming processing : adopts streaming processing technology, supports real-time response to voice commands, providing a smoother interactive experience.

Application scenarios

  • Intelligent customer service : Provide intelligent customer service services through voice interaction to improve customer experience.

  • Educational learning : Read textbooks aloud and provide voice feedback to help students better understand the content.

  • Smart Assistant : Provide voice interactive services in smart homes, mobile devices and other scenarios.

  • Content creation : Generate audio books, podcasts, voice news, etc. to enhance content expression.

  • Accessibility Assist : Provide voice assistance for visually impaired or dyslexia to improve information acquisition ability.
