The Windows Phone app which has gone free next as myAppFree app of the day is Say Mail!. This is a simple and very powerful tool to compose emails using dictation.
Say Mail! Description:
Dictate an email, optionally have it read back to you, choose an email address (from contacts, or quick list), then hit ‘Send’. The email is composed and is ready to go!
Free trial is fully functional with ads, or buy the full version to remove the ads!
You can speak words, punctuation (comma, period, question mark, etc), as well as layout shortcuts (new paragraph, new line,etc). Dictations append, so you can take your time, and left/right flick to undo/redo last edit.
This application uses top of the line Dragon dictation/text to speech technology by Nuance.
The design here is nothing fancy but it does what you need it to do quickly and efficiently, without distracting you with extra bells and whistles.
Today it is free!!! What are you waiting for???
