Excel 2010 speech recognition

I am using Windows 7 and Excel 2010.  I undestand that speech recognition is not an automatic part of Excel 2010.  However, Windows 7 speech recognition works with Excel 2010.  However, I am having a hard time finding the commands to use with speech recognition in Excel.

I am thinking that the technology for voice dictation (like for a letter) is not quite there, but it appears to me that there may be possibilities for doing tedious data entry work in programs like Excel.  However, most of what I can find by way of tutorials for speach recognition does not address Excel directly. I am looking for the simplest easiest way to do things. For example, I can say one seven seven, and 177 gets entered into a cell, but then I have to say insert.  Is there a way to get around that (having to say insert each time).  I have tried 177 move down but then it types into the cell 177 move down.
Also, if I say one two three four, it interprets it 1 to 3 4. Is there a way to inform it that whatever I say next should only be intpreted as a number?

Is anyone using Speech recognition with Excel with good results?  It seems like it could be real helpful under certain circumstances, but practically speaking, it is?

Any help appreciated

I see speech recognition good in limited vocabulary situations.  Any further help I could find with regard to how to use  recognition in Excel 2010 or Access 2010 would be most appreciated.
