I'm not familiar with a specific individual named 张桂源 (Zhang Guiyuan) who is known for AI singing、It's possible that this person is not a public figure or is not wellknown for their work in AI singing.

However, I can tell you that there are many AI singing tools and software that use artificial intelligence to generate singing voices or assist with vocal production、Some popular examples include:

* AI singing software like Vocaloid, which uses a synthesizer to generate singing voices
* AIpowered vocal processing tools like AutoTune, which can modify and enhance vocal performances
* AIgenerated music and singing platforms like Amper Music, AIVA, and Jukedeck

If you're interested in learning more about AI singing or would like to know more about a specific topic related to AI music generation, feel free to ask and I'll do my best to help!
