Are there any free Russian text-to-speech converters?

Question

speech synthesis

Subject

Main requirements:
1) To be more or less qualitatively. The voice is not like from the womb of a robot and the stress is not often confused.

Highly desirable:
1) Support for mixed text (Russian interspersed with English words)
2) At least a couple of votes

If there are no free normal ones, then tell me paid ones for a sane price tag.
