FunAudioLLM

FunAudioLLM is an innovative framework developed to enhance natural voice interactions between humans and large language models (LLMs). It comprises two core models: SenseVoice and CosyVoice, each designed to handle specific aspects of voice understanding and generation.

SenseVoice: Voice Understanding Model

SenseVoice excels in multilingual speech recognition, emotion recognition, and audio event detection. It offers two variants:

• SenseVoice-Small: Supports speech recognition in Chinese, English, Cantonese, Japanese, and Korean, delivering low-latency performance.

• SenseVoice-Large: Capable of recognizing speech in over 50 languages with high precision, making it suitable for diverse linguistic applications.

CosyVoice: Voice Generation Model

CosyVoice focuses on natural speech generation with control over multiple languages, timbre, and emotion. It offers several capabilities:

• Multilingual Voice Generation: Generates speech in various languages, including Chinese, English, Japanese, Cantonese, and Korean.

• Zero-Shot Voice Generation: Produces speech in new voices without additional training data.

• Cross-Lingual Voice Cloning: Allows cloning of voices across different languages.

• Instruction-Following Speech Generation: Generates speech based on textual instructions, enabling control over speech characteristics.

Applications of FunAudioLLM

By integrating SenseVoice and CosyVoice with LLMs, FunAudioLLM facilitates several applications:

• Speech-to-Speech Translation: Enables real-time translation between languages while preserving speaker characteristics.

• Emotional Voice Chat: Allows interactions where the system understands and responds with appropriate emotions.

• Interactive Podcasts: Facilitates dynamic podcast experiences with multiple voice personas.

• Expressive Audiobook Narration: Delivers engaging audiobook readings with varied emotions and styles.

Open-Source Contributions

The models and codebases for SenseVoice and CosyVoice have been open-sourced, promoting transparency and encouraging further research and development in voice interaction technologies.

FunAudioLLM represents a significant advancement in voice interaction technology, offering tools for more natural and expressive human-computer communications.
