I would like to speak in Russian and get it converted into text. Is that even possible? I only have Windows 7 English edition.
Windows 7's in-built Speech Recognition is available in English, French, Spanish, German, Japanese, Simplified Chinese, and Traditional Chinese.
With the English language you will have 2 language options, English (US) and English (UK) to choose from.
If you want to add any of the other available languages, you must install the Language Pack for that language.
The MUI language packs are only available in the Ultimate and Enterprise editions of Windows 7.
