Russian speech corpus for a neural network. Create your own or have ready-made ones?

Question

Neural networks

Required data in the form of audio + transcription. I downloaded a 2.9GB data corpus from voxforge. For command recognition, this is enough, but I would like to improve the quality. The English-language public domain data corpus is much larger. In this regard, the question is whether there are resources where you can download (perhaps even commercial) just a ready-made speech corpus. Share links, please, if anyone knows.

Answer 2

Movies + subs are not suitable for them as raw materials?
