June 24 (Reuters) - Major record labels Sony Music , Universal Music Group and Warner Records sued artificial intelligence companies Suno and Udio on Monday, accusing them of committing mass copyright infringement by using the labels' recordings to train music-generating AI systems.

The companies copied music without permission to teach their systems to create music that will "directly compete with, cheapen, and ultimately drown out" human artists' work, according to federal lawsuits filed against Udio in New York and Suno in Massachusetts.

Representatives for Suno and Udio did not immediately respond to requests for comment on the complaints. (Reporting by Blake Brittain in Washington)
