Text to speech software?

[desidude]

Hi friends,

I need to convert some Microsoft Word 2010 text (10-15 pages of notes) into audio and save it as an audio file, e.g. MP3

I am using Windows 7

Can you suggest any program that I can do this with?

I believe Microsoft has a narrator tool, but I am not sure how to record the output?

Thanks so much,
Desidude
