At last, some code!
In the Load function of the form input the following code:
Private Sub Form_Load()
Dim totaldata As String
'define configuration
'[Grammer], set language to english (1033)
'[<Start>], define the words we are looking for
totaldata = "[Grammar]" & vbCrLf & _
"langid = 1033" & vbCrLf & _
"type=cfg" & vbCrLf & _
"[<Start>]" & vbCrLf & _
"<start>=Notepad" & vbCrLf & _
"<start>=Volume" & vbCrLf & _
"<start>=Media Player" & vbCrLf
DirectSR1.GrammarFromString (totaldata)
DirectSR1.Activate
So this is how the string looks. For each line that contains a word, a tag
"<start>=" is used to signify a word that follows for the DirectSR
to recognize. In the sample code, three words are used, they are Notepad, Volume
and Media Player. Guess what? Right, we will use these words for the voice command
to load these programs. In addition, the DirectSR1.Activate is used to start
the engine to begin recognizing voice commands. DirectSR1.Deactivate is used
to stop the engine from recognizing voice commands.
We are almost set. All we have to do is return to the PhraseFinish procedure
to parse the command.
From here on is pretty simple, remember that the Phrase parameter is all we need
to be concern about. Just put the following code in the PhraseFinish procedure:
Dim sFile As String
Dim noth As Long
Select Case Phrase
Case "Notepad"
sFile = "\system32\notepad.exe"
noth = ShellExecute(0, "OPEN", Environ("SystemRoot")
& sFile, "", "", 1)
Case "Volume"
sFile = "\system32\sndvol32.exe"
noth = ShellExecute(0, "OPEN", Environ("SystemRoot")
& sFile, "", "", 1)
Case "Media Player:
sFile = "C:\Program Files\Windows Media Player\mplayer2.exe"
noth = ShellExecute(0, "OPEN", sFile, "",
"", 1)
End Select
Here is the low down or lodown :). When the DirectSR recognizes a sound, it
will process the sound into a word that may closely match the one you provided.
If it matches, the Phrase variable will contain the matched word. And lo and
behold, the code we use is a Select Case just for the Phrase variable for the
words we fed in the engine in the load function. When a match occurs we will
use an API function ShellExecute() to load the program.
