I believe that you can train it more and more, in order to help it better understand you. I think you access that thru normal gui dialogs.
Here's to hoping that some speech SDK SME jumps in and answers our queries...

I'm new to the Speech API, but I can at least answer this question:
| TodWulff wrote: | | How the hell is the script triggered to cause the OnRecognition function to kick off? |
COM_ConnectObject connects events exposed by an object to the corresponding functions in script.
If I understand COM_ConnectObject correctly, it works as follows:
Retrieve an IConnectionPoint interface (pconn) representing the events exposed by the object.
Construct an object and an IDispatch interface. This object is referred to as an "event sink" (pevent or psink.) RegisterCallback and NumPut are used to construct the interface, with the actual code contained in COM_DispInterface.
Call pconn->Advise(psink) to create a connection between the connection point and the event sink.
When the source object raises an event, it calls the Invoke method of our event sink. On the AutoHotkey side, COM_DispInterface is executed with A_EventInfo == 6. RegisterCallback and DllCall are used to dynamically call the appropriate function, based on a script-defined prefix and the name of the event being raised.
| Quote: | i.e. what faculties of AHK are you employing to cause this functionality to exist.
|
In summary:
- NumGet and DllCall to call methods of COM interfaces.
- VarSetCapacity, RegisterCallback and NumPut to construct a COM interface.
- RegisterCallback and DllCall to call a function dynamically.
Edit:
Okay, now I can answer another one.

Replace everything from COM_Init() to ExitApp with:
| Code: | COM_Init()
plistener:= COM_CreateObject("SAPI.SpSharedRecognizer")
pcontext := COM_Invoke(plistener, "CreateRecoContext")
pgrammar := COM_Invoke(pcontext , "CreateGrammar")
COM_Invoke(pgrammar, "DictationSetState", 1)
; No rules to set up!
pevent := COM_ConnectObject(pcontext, "On")
Return
CleanUp:
COM_Release(pevent)
; No rules to clean up!
COM_Release(pgrammar)
COM_Release(pcontext)
COM_Release(plistener)
COM_Term()
ExitApp |

| Sean, can you please explain in laymens terms why COM Standard Library of this is recommended over the previous CoHolper version? Is there any major compatibility, performance, or other differentiations? |

As info, I determined what was causing this issue for me. I was making use of a downloaded version of the COM.ahk wrapper. Once I deleted it, and the associated #include in my scripts, allowing AHK to look in the lib folder for the version included with the latest version of AHK, the no interface issue disappeared.
I post this herein, in the interests of allowing others to learn from my 'mistakes'.
Take care.

Is there a way that the speech api can have it's 'ears' plugged for just a bit? In my IDE app, I am making use of COM TTS as well as the VR functionality.
The damn scripts tend to get into some goofy loops when the app hears itself...
Please advise. Thanks, in advance.

You can either disable the rules you've created or disable speech recognition entirely. You'll probably want to disable speech recognition entirely to avoid triggering some other command or dictation.
| Code: | ; Disabling a rule:
COM_Invoke(pgrammar, "CmdSetRuleState", "wordsRule", 0) ; 1 to re-enable
; Disabling speech recognition:
COM_Invoke(plistener, "State=", 0)
; 1 = active if any rules are active
; 2 = always active

Hey, can someone please suggest a rememdy for this problem below?
.... I like this script by Sean allot, but have one gripe (not his fauilt), ... but in Windows Vista, when I run this, ... I am getting that little Ms Listener Voice Recognition widget, that overlays on top of the gui of my application. I'd rather not see this. Can anyone suggest a remedy, and know how to not have that appear, yet have this voice functionality still work? :confused:
Thanks allot!! |

Unfortunately I can't help you here myself, no access to Vista. I hope other members who can access Vista help you out of the problem. |

I was directed to this post from another post.
| infogulch wrote: | | It seems to work similar to "OnMessage()", does COM set that up? or is OnRecognition a built-in function by it's own right? |
As a matter of fact I mimicked the name OnMessage for OnRecognition. But it looks like add more confusion, regretfully. OnRecognition is more like a callback, and composed of as On + Recognition where On is a custom prefix which can be chosen (by the user) to be any word like Voice_, etc or even an empty string. The voice COM object is aware of and thus callbacks only with the name Recognition, then COM.ahk combines it with the user's chosen prefix On then finally calls the function OnRecognition() if already exist in the script. Notice the line | Code: | | pevent := COM_ConnectObject(pcontext, "On") |
| Quote: | | How would I clear words from being recognized anymore? |
I don't have much to say on Voice Recognition as I haven't used it myself. I own no facility to use with. But looking through the documentation, seems to be able to do it by creating another ISpeechGrammarRuleState (say pstate1) which will remain inactive, then transit the word(s) you want to disable to it from the current active pstate. E.g.,
| Code: | | COM_Invoke(pstate, "AddWordTransition", "+" . pstate1, "One Two Three") |
or | Code: | | COM_Invoke(pstate, "AddWordTransition", "+" . pstate1, "One|Two|Three", "|") |
| Quote: | | Is there a way to tell it to receive All words SDK recognizes? |
Again according to the documentation, seem to be able to use (maybe in conjunction with DictationLoad and/or DictationUnload) | Code: | | COM_Invoke(pgrammar, "DictationSetState", 1) |
Refer this | Code: | Enum SpeechRuleState
SGDSInactive = 0
SGDSActive = 1
SGDSActiveWithAutoPause = 3
SGDSActiveUserDelimited = 4
End Enum |
PS. Well, I now noticed that this post has another page. If want to control them in entirety, read the posts by Lexikos. |

Thank you Sean and Lexikos! That clears some stuff up for me. Even helps me understand the COM.ahk lib better. I'll have to take a closer look at the sdk documentation, I think it was way over my head when I posted before. (who am i kidding? still is..  )
Thanks again for your replies!

| Hey, just curious, is anyone aware of a way to get rid of the annoying voice-bar GUI widget that appears over my apps, on Windows Vista+, when invoking voice? |
