Hi

What do I need to make a mobile application to type what you want to say and convert it to a PDF file or DOC file.

I mean : Typing without using keyboard.

So if you are not using a keyboard, you are either using Gesture's or perhaps Speech to Text converter?

I did it. From what I know, nearly hopeless, in fact. You can easily develop application recognizing few commands, but dictation... I would forget about it.
Maybe I'm unfamiliar with some more advanced products, I heard they exist, but never personally tried...

I have never had to develop a speech recognition program but below are two sets of references for you to start your research.

Microsoft Speech Technologies
* System.Speech Programming Guide for .NET Framework 4.0[^]
* Microsoft Speech Platform[^]

Dragon Dictate software
* Dragon NaturallySpeaking
* Dragon Mobile Apps
* Google Search for more Dragon Dictate articles

Good links, my 5.

Unfortunately, Dragon software is proprietary and commercial. As to the engine which comes from Microsoft free of charge for OS users, I tries it a while ago. It is done using DictationGrammar, but the results were disappointing, practically useless. It worked reasonably well only with small grammars, with would be good enough for command-driven UI, but not for dictation.

So, my question is: did you try Dragon dictation? If you did, how was that?
