Sapi 5 Add Words To Voice Recognition Dictionary


Hello, I am using the SAPI5.3 api in a sample vb app...the app has the following code:
Code:
'=============================================================================' This sample demonstrates how to do simple dictation in VB with SAPI 5.1.'' It uses shared reco context object, uses the default audio input, loads in' dictation grammar, sets up event handlers, and shows the recognized text in' the dialog text box.'' Note: since the text box is using system locale, it may not correctly show' characters in other languages. For example, if you use Chinese Speech' Recognition engine as the default engine on your English OS, the text box' may show garbage even though the engine recognizes Chinese.'' Copyright @ 2001 Microsoft Corporation All Rights Reserved.''=============================================================================Option ExplicitDim WithEvents RecoContext As SpSharedRecoContextDim Grammar As ISpeechRecoGrammarDim Voice As SpVoiceDim m_bRecoRunning As BooleanDim m_cChars As IntegerPrivate Sub Form_Load() SetState False m_cChars = 0 Set Voice = New SpVoice Timer1.Enabled = TrueEnd SubPrivate Sub btnStart_Click() Debug.Assert Not m_bRecoRunning ' Initialize recognition context object and grammar object, then ' start dictation If (RecoContext Is Nothing) Then Debug.Print "Initializing SAPI reco context object..."

This program will add any text spoken to the textbox...my problem is some words are not recognized...is there a way to add these to a 'dictionary' like you can with ms words voice recognition?

SAPI speech recognition ...?

Voice Recognition, Not Speach Recognition..
hi everyone!^^

hope you could help me out a bit..^^

1. do any of you know of any algorithm on voice recognition? not the speach-to-text/text-to-speach thingy.. i want an algorithm that could determine whose voice it was which was played.. for example, i would have a database of wav files of different people and when i receive a voice from the mic, the algo could determine, based on the current database, whose voice it was.. is this possible?

2. is it possible to detect and delete the start and end of a wav file which has no sound? like for example, from wav file recorded from a mic.. there is bound to be some part at the start and end of the wav file that has no sound right?

THANKS!

Voice SAPI
Im totally new to VB. The following code works on Windows XP but not on Windows 2000. I'm thinkng windows 2000 has some outdated version of VB or Voice SAPI. I searched around MSDN but I didn't really find anything about what OS has what version.

All I am trying to do is to make a script say something. Does anyone know the corresponding VB code that would work on Win 2000 or tell me what I need to install on Win 2000 to make the following work?

Set ISpeechVoice = CreateObject("SAPI.SpVoice")
varname = ISpeechVoice.Speak("Hello", 0)

Voice Recognition
Hi all
I have this video database proggy that im trying to run on my dvd computer.
Now my dvd computer sits in the lounge room with a tv as a monitor and i watch my dvd collection from the hard drive.
Now I though it would be very cool and impressive when ppl come over is to add voice recognition
Now i have no problem working the VoiceRec it works fine. My problem is this...

when i add a movie title to the database in order for the VoiceRec to recognize the movie title i have to add the following:

the gramma file is linked to a txt file so updating that is no problem and easy

However i came to relize this
Example

VB Code:
Private Sub reco_PhraseFinish(ByVal flags As Long, ByVal beginhi As Long, ByVal beginlo As Long, ByVal endhi As Long, ByVal endlo As Long, ByVal Phrase As String, ByVal parsed As String, ByVal results As Long) If Phrase = "Show me top 10" And Disallow Then        Bot.Play "DoMagic1"        Bot.Play "DoMagic2"     End If     '''''''''' PHRASE 2    If Phrase = "Play Pretty Woman" Then        Bot.Play "DoMagic1"        Bot.Play "DoMagic2"            Bot.Play "Idle1_1"        Bot.Speak "Launching Movie"        Exit Sub        ' This will launch the RAW DvD file with the default application        Shell "C:prettywoman.vob", vbNormalFocus    End If


My question is how can i run phrase 2 and all of its coresponding code from a database
and not have to update the code manually every time a new entry is submitted.

I hope this makes sense
thanks in advance

Voice Recognition...
Hello...
HOw can I use voice recognition in my program?

Voice Recognition
Anyone successfully incorporated voice recognition into their apps.

As I understand it voice recognition is in its infancy, so the quality available is dubious, approx 60% success, even with trained engines.

Can anyone suggest an accurate voice recognition engine, or should I avoid trying to incorporate this feature?

Voice Recognition
pls tell me if there is a difference between MSAgent and Direct Speech recognition control. and i downloaded a couple of speech recognition and MSAgent examples but when i said stuff, nothing happened. I tested my microphone with Netmeeting 3.01 and it's working. Something wrong???

pls reply asap,


THANX IN ADVANCE!!! ^_^

Voice Recognition Help
Hi all,
I'm new to these forums and very new to VB I'm currently writing an app that requires Voice recognition I only require two commands:

Play
Stop

I downloaded the Microsoft Voice Recognition Software at
http://msdn.microsoft.com/workshop/i...agentdl.asp#sr

And I don't have a clue how to use It I would really Aprecitte It if someone could point me in the right direction and maybe a bit of code
Thanks,

Does anyone know where I can find a beginner to intermediate course for VB's voice recognition online?

Thanks!

Voice Recognition
I read the article "Writing your first speech recognition program", and was intrigued enough to try it. But I'm having problems with the code...

Private Sub Form_Load()
Dim totaldata As String
Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
    totaldata = totaldata _
    & "<start>=Notepad" & vbCrLf _
    & "<start>=Volume" & vbCrLf _
    & "<start>=Media Player" & vbCrLf
    
    DirectSR1.GrammarFromString (totaldata)
    DirectSR1.Activate 'start engine to begin recognizing voice commands
End Sub

I believe this code is to load an API function ShellExecute() when a voice match occurs.

The italicized is where I am getting the error "Compile error: Only comments may appear after End Sub, End Function, or End Property". Is the code in the proper module? The article states: "To declare the API put the following code on top of the form module". The code being referred to is the function line that is getting the error. So, I thought maybe I had it in the wrong module.

I hope this is enough to go on. Please help.

Best regards,

Hal

Has anyone done anything with voice recogition and VB? I am going to be creating an application
that will be used for dictation. It is supposed to be able to plug in the tape recorder output
to the Audio In for the sound card and they can play their tape of dictation and it will read in
all the words and put it into this special documentation software. If anybody has any ideas
or has done something similar please let me know.

Using Voice Recognition With VBEditor?
Does anyone have any experience using voice recognition as a way to enter code inside the VB Editor? I am a programmer with tendonitis and I am wondering if this might be a way to alleviate my condition while I work. I am considering Dragon Naturally Speaking but the professional version (which allegedly works with the Excel VBE) is $695!

I am doing mostly Excel VBA for Excel 2000. I am using Windows XP Professional.

Thanks!

Voice Recognition And Comparison?
Hello,

I'm interesting in playing around with voice recognition. What I'd eventually like to create is basically a voice-authorization console where it takes a short speech recording of a preset phrase and compares it to a pre-recorded sample to see if it is the same person.

Now, I'm at a loss as to how this should be gone about.

I believe I read somewhere that voice comparison is done through numerous different aspects of the Voice, such as Pitch, Tone, and/or Frequency. I'm unsure where I read this, and if it's even true, so if anyone could give some insight here, that would be great.

What I was basically thinking, in pseudo-code, would be the following sort of path:

1) Prompt user to Say String, and hit a key (To stop recording)
2) Extract Needed information from recorded sample (Pitch/tone/whatever?)
3) Compare these to known values, and if they are in a set threshold, grant access (Within a few points, allowing for fluctuations of the voice), or else deny it.

Any help on the subject would be great.

Thanks.

Voice Recognition Where To Start
hi guys,
i am a newbie and I really need your help.
I have developed some in interest in voice recognition or speaker identification but I Have no idea on where to start.
My desire is to be able to have the computer store voice files in database, compare them and retrieve them in a way that when i input it can discern that it is i , and when somebody else does input their voice it can identify the person; in case there is an input of a non registered it will give a notification of no match.

Voice Recognition Analysis?
Hey all,

I have a functional program I built in VB6 which uses Directspeech recognition. I have my system configured to utilize audio files in the recognition engine as opposed to using a microphone. The problem is, I need it to analize the voice patterns of the speakers on the wav files (there are always at least 2 speakers) and be able to recognize that a new speaker is talking. Is this possible?? I used the SimpleDict code from the MS Speech SDK 5.1.

Thanks,

Voice Recognition To Trigger Functions
I have a sheet with a bunch of buttons and I want to be able to trigger them using speech commands.

I've installed the Speech SDK and the engine. Once that was sorted out I managed to add a bunch of references; VoiceCommand 1.0 Type Library, Microsoft Voice Commands and a few other text-speech related items.

I have no idea what functions to use to make voice commands work. I've looked extensively on the internet and I've managed to find some examples for VB2008 and VC++ but nothing for VBA. Maybe it can't be done but could anyone point me in the right direction? Maybe I Dragon NaturallySpeaking can get this done?

Thanks.
