Why does Google Voice Typing transcribe certain words incorrectly, and not offer alternatives?

There are a few words that I use in everyday conversation that Google Voice Typing doesn't seem to want to recognize. The first is "extraordinarily." It always transcribed "extraordinary Lee." The other two words (in censored format, since I imagine vulgarities are kinda frowned on in the forums) are the s-word with the suffix "ty" appended, and the mf-word. The former is always transcribed with only one T. The latter is spelled without the C. I swear a great deal. It's how I talk. I'm also a stickler for proper spelling and punctuation, so it bothers me that Google spells cusswords like a fourth grader, in addition to the other typo. Also, recently it seems that all the options for corrections have disappeared--every time I dictate something, there are NO words underlined at the end. What gives? Anybody got any input on this?
