Speech Dictation

Gud Day all
I've been trying to solve this problem for quite some time now...I hope someone might have a clue or at least a place where I can learn more about the issue;
you see I've managed to make the speech dictation provided by MS to work using VB.NET, and it writes everything perfectly; what I'm trying to do is disable the grammar and the vocabulary list, since it is using the English words; what I want to do is basically type out what the user says with out forming up the correct word; or let me say type the combination of phonemes...
any ideas?

thnx in advance
Regards
Abraham

Which translates sound into known words.

Sounds aren't mapped to a phoneme by the SAPI. Phonemes can't be interpreted, and can't be mapped to a series of characters. A single letter has a different sound in a different language, and there is no version that tries to map "generic sounds" to a generic alphabet.

An alternative would be to record the sounds yourself (DirectInput) and use AI-algo to classify it (to map the sound to a/a serie of chars)

The latter option is quite a challenge, I suppose. I hope that someone else posts an answer that I missed Smile | :)

Thnx Eddy

; and if you may; is it possible using SAPI to dictate the english letters; let us say if the user says "parlon" it would be written as said or close to it; not necessarily makes sense. any thoughts on that?

Yup, but then you'd be spelling each word, e.g. "Hotel Echo Lima Lima Oscar" for "Hello".

AbrahamMOKDAD wrote:

That's what happens when you try an English word; it tries to map the sounds to match up to the sounds of a known word. You could start at the .NET classes for speech recognition, in the System.Speech.Recognition[^] namespace. There's also a cool example right here on CodeProject[^].

Problem with frames.

I am creating a VB application. I have 3 buttons and 3 frames. I want to load one frame on click of a particular button.
I am keeping one's visibility true and another one's visibility false. But when I run the application, none of the frame appears.
Why is it so?
Plz help me.
Thanks.

You might just as well ask "How long is a piece of string?".

There is no answer to your question because no one knows what you have done nor how you did it.

Edit your post to show the relevant code. Read the guidelines first here[^], paying particular attention to items 4, 5 and 7.

Not allowing a program on a CD to be copied

13-Oct-09 5:01

First, since "frames" most commonly applies to web applications, you're going to have to specify if this is a web app (there is an ASP.NET forum here for these questions) or a Windows Forms app. Second, if this is a Windows Forms app, how did you implement these "frames"? What controls did you use and how were they arranged? What are the initial properties, like "Visible"? Show the code you're using to hide one "frame" and how another.

Hi,
I have a program on a CD which I am eventually hoping to sell. Is there anyway that I can put a bit of code on the CD to stop copys of the CD being made.

The program has to be read from the CD as the CD contains videos.

I am using vb.net

Many thanks
Dan

Sony tried, and they failed. There is no fool-proof way to prevent the duplication of CD's.

You might want to try limiting the number of installations, by asking the user for a registration-key upon installation (or the first start of the application).

There is no way to prevent this. Copy protection has been the industry's Holy Grail for decades and noone has been able to stop the unauthorized duplication of media.

Even if the videos were is a custom format that no other player could read and the play that COULD read it was supplied by you AND the player "phoned home" to check its license every time it play one of your videos, it could still be cracked.

The bad guys could still use the player's code against itself, having the player decode the video for them and giving them enough information to write their own converter to recreate your videos in a standard format. They could even break the player and trick it into thinking it was getting an OK signal from your licensing server.

The bottom line is that there is no such thing as "copy protection"...

File name Parsing

IvanIT12-Oct-09 5:45

12-Oct-09 5:45

I am working with file names like so: Medic.01.xy.123.654.1001.txt

My main goal is to ascertain the value of the xy segment of the filename. over time the values will range from 11, 13, 15, 16. Then depending on these values, I will need to map to other variables like Hand, Foot, Head or Stomach.

Can I get some assistance is a direction I can go with this project? Thanks

Take a look at the Split() method of the String class.

IvanIT12-Oct-09 6:09

Thanks Henry; this is exactly what I need.

Any other pointers on how to assign variables to each part of the name after the split?

It depends on how many parts there are but one technique is to leave the parts in a String Array and then either use Constant values or an Enumeration as an indexer. Something like:

Enum PathParts
  Originator = 0
  XY = 1
  .......
  .......
  .......
End Enum

' OR
Public Const Originator = 0
Public Const XY = 1
.......
.......
.......

' Assuming your String Array is called SplitPath
' you can then refer to the different parts like this
SplitPath(PathParts.Originator)    ' SplitPath(Originator) if you use Constants
SplitPath(PathParts.XY)    ' SplitPath(XY) if you use Constants

Visaul Basic program giving me fits!

12-Oct-09 6:41

this is what i have going on so far.

<br />
Module nameSplit<br />
<br />
    'sectionize the name of claims file to ID program locationID<br />
<br />
    ' The file system path we need to split<br />
    Dim nuFile As String = frmMain.lblClaimsFile.Text<br />
<br />
    ' Split the string on the period character<br />
    Dim segments As String() = nuFile.Split(".")<br />
<br />
    Public ProgLoc As String = segments(3)<br />
<br />
    <br />
'ID location Code by program code<br />
        Dim progCode As String<br />
        If ProgLoc = "02" Then<br />
            progCode = "6355"<br />
        End If<br />
<br />
End Module<br />

I think it is gonna work.

Henry, thanks again!

This should calculate and display the total amount due. There are 3 radio buttons, A, B, C...Nonprofit should get a 20% discount from final charges. I'm supposed to have three radio buttons (package a, b, and c), and one check box (non-profit). If non-profit is selected, a 20% discount should be deducted from final charges. The number of hours used in a month cannot exceeed 744. Value must be numeric. Also, the packages are internet service providers, each has it own set price, a-10 hours=$9.95, additional hours=$2.00 per, package b-20 hours=$14.95, additional $1.00 per hour and c- unlimited for $19.95.STILL having problems with this.....I can't get the prices to load. And the longer I work on this, the messier it gets.......can someone take a look at it and see if you can help.

You should NOT be using the Strings in your TextBox's directly in your calculations. You've done no vlidation of the entered data and have not converted the Strings in those boxes to numeric data types that will fix just about all of your problems.

I was just looking for some help, not criticism...this is the first Visual Basic class I've ever taken. It's not the simplest of concepts to everyone.....some of us spend the whole semester hoping and praying we get through the class without failing, even when we do ask for help. Some get it, some don't. the other programs I've written for the class were fine, this particular one has me sratching my head. I apologize for getting nasty, but again, I just wante help, not criticism for not knowing how to do it.
