NetEase Youdao releases open-source "EasyVoice" speech synthesis engine, offering various voices and emotional functions for free.

"YiMoSheng" is a TTS engine developed by Youdao, which supports both Chinese and English languages. It can synthesize over 2000 different voices and can also generate voices with various emotions such as happiness, excitement, sadness, and anger based on the emotional cues in the text. It is more natural and realistic compared to traditional TTS systems. Users can download and use it for free on GitHub, and they can also conveniently select and apply voices through the web interface and batch generation API. CEO of Youdao, Zhou Feng, expressed the hope that by open-sourcing "YiMoSheng," it can help developers and content creators with demand to expand the application scope of high-quality TTS. Feedback and suggestions from everyone are also welcomed. Youdao has invested in and innovated in the field of TTS for many years, launching a series of applications and products such as the first celebrity voice feature in the education field and the virtual human language private tutor, Hi Echo. This year, Youdao has also become a member of the first batch of "Beijing General Artificial Intelligence Industry Innovation Partner Program," participating in the formulation of the first "General Artificial Intelligence Model Series Standards for Education" and launching the first vertical large-scale model in the education field, "ZiYue," and achieving the implementation of six major application results.
