Description

CosyVoice is a sophisticated voice cloning and speech synthesis model developed by Qwen Cloud, part of the CosyVoice series, which is specifically aimed at enhancing professional applications in text-to-speech with notable improvements in audio quality, naturalness, expressiveness, and cloning accuracy. This model can generate a custom voice that closely resembles the reference audio after a brief recording, requiring just 10–20 seconds of clear speech to achieve optimal results, although a minimum of five seconds of uninterrupted dialogue is essential. It is equipped for real-time streaming text-to-speech synthesis, which enables applications to process text and deliver audio with minimal initial latency. Supporting multiple languages including Chinese, English, French, German, Japanese, Korean, and Russian, the model offers language hints during the enrollment process to facilitate better voice identification. The source recordings accepted by the model can be in WAV, MP3, or M4A formats and should consist of clear speech devoid of any background music, noise, or other speakers to ensure the best possible output. Overall, CosyVoice stands out as a powerful tool for creating personalized voice experiences in various linguistic contexts.
