I used Forvo to listen how native Russian speakers pronaunce девочка. I don’t hear that о in девочка is pronaunced. Should it be inaudible?
An e-mail about "4-day pronunciation training" sessions of some sort, which may be of interest, showed up in my e-mail just now. Acc. to the note::
HERE IS WHAT I´LL BE COVERING:
- A syllable and a stress and how they affect Russian pronunciation (Day 1)
- When O is pronounced as A. Hint: O can sound as A, as a short A and as an English schwa in different positions. That´s 3 different sounds! (Day 2)
- The rule of first И aka when И is pronounced as Ы (Day 3)
- Consonant combinations (TC, ДС, ТСЯ, ТЬСЯ, and so on) with the Ц sound and how to read them (Day 4)
I have no idea if it is good or not (but I suspect it is), nor do I know if there may be any strings attached somehow. But it looks like it addresses on day 2 what you asked about. . . . And it agrees w/ my other comment. :)
