I’ve been looking for a Russian text-to-speech solution, since Google Translate brought the captcha hammer down on my previous script 
I just found a program called “balabolka” which seems quite capable and is well reviewed. Do any other course creators have experience with this program, and do you have any hints or tips for putting it to good use? I plan to use it for my next Russian course, and will report on my experiences with it.
I use Balabolka sometimes, it is good but AFAIK it does not have its own voices (and the only decent Russian voice I know is from Acapela)
