Voice recognition

[dj_vibri]

Hello,

for my evening-course VB.NET we have to make some programme which can connect to a database etc...

My first idea was to create some "OS" based on voice recognition. A little bit more in detail:

When PC starts, automatically the VB.net programme start in full screen (no windows XP/vista/... visible), they say their name through a microphone and when the programme recognize them they are granted to log in. When they login the programme connects to a database where the administrator specify which programmes the logged in user can be use by just placing selections to, for example notepad & MS Word.

The user will see a shortcut icon on their desktop from notepad & word. Afterwards they could open notepad etc... by just saying the programme name but that's beyond this scopes question It will be in another topic when I have problems about that.

The main problem is: Is it possible to have VOICE recognition in VB.NET? I have found speech recognition but when I implement it with speech recognition everyone could just say the name of a person and they will be granted to login. I need some voice recognition based on the "tones" of the volume etc...

someone got an idea?

Thanks in advance,

Pieter

Hi JohnH,

thanks for the quick reply and I'll test it hopefully this evening when I'm home from work. But I thought that the speech SDK was to dictate something instead of voice recognition...

Am I missing something?

It works both ways, text-to-speech and speech-to-text

So let's say that I implement it with speech SDK and let say that I'm the administrator of the programme. I just have to say my username "administrator" and I'll be granted to login. Another person that says "administrator" will not be granted because the speech sdk recognize a difference between the two voices?

Sorry for my questions but I'm a beginner vb.net programmer but I want to do that for my end-work (or how you say it in English )

No, it will simply try to interpret your sounds as some recognizable word in a dictionary. You probably have to practice to talk computerish correct english to let it recognize the words you want. You could instead use it to recognize different spoken user passwords.
