Confucius4

Confucius4 is a new text-to-speech system created by NetEase Youdao. It is designed to turn written text into natural sounding speech. The main goal of this tool is to support many different languages and to keep the same voice even when the language changes. This makes it very useful for people who need to speak in multiple languages without having to record new audio files every time.

Benefits

Confucius4 offers several powerful features that make it stand out from other speech tools. It supports fourteen languages including Chinese, English, Japanese, Korean, German, French, Spanish, Indonesian, Italian, Thai, Portuguese, Russian, Malay, and Vietnamese. One of its biggest advantages is that it does not require a reference transcript to clone a voice. This means users can create a voice without needing to provide extra text samples. The system also allows for cross-lingual voice transfer, which lets users switch between languages while keeping the original speaker identity. This is helpful for creating unaccented speech across different languages. Another key feature is seamless emotion transfer. This ensures that the cloned voice carries the same feelings and tone as the original speaker. The system shows strong performance in real-world scenarios where multiple languages are used together.

Use Cases

Confucius4 is useful for many different applications. Developers can use it to build applications that support multiple languages without needing separate voice models for each language. Content creators can use it to generate audio for videos or podcasts in various languages while maintaining a consistent narrator voice. Businesses can use it for customer service bots or automated announcements that need to speak in many languages. Researchers can use it to test how well speech systems work across different linguistic boundaries. The tool is also suitable for educational apps that need to teach pronunciation in several languages. Since it is currently available as an online demo, users can test it immediately to see how it works for their specific needs.

Pricing

Pricing details are not available for Confucius4 at this time. The project is open source and the code and model weights are expected to be released soon. Users can currently try the online demo to explore its capabilities.

Vibes

There are no public reviews or testimonials available for Confucius4 yet. The project is still under preparation and has not been widely tested by the public. The available data comes from technical benchmarks comparing its performance against other speech systems. In these tests, Confucius4 achieved competitive results in terms of speech accuracy and speaker similarity across many language pairs. For example, it showed low error rates when translating speech from English to Chinese and from Japanese to Chinese. The system also performed well in maintaining speaker identity when switching between languages like German to Chinese or French to Chinese.
