Problem with Sapi 5 implementation


Recommended Posts

 Hello all"
I have curious problem with com object implementation of Sapi 5.1.
In some cases }Some Voice engines] the metods for retrieve the voice parameters fails with error :Member not exists:.
But the Retrieved Voice object can speak the given text, so It exists and work.
Example of this type of Engine can be this one: http://download.kobavision.be/KobaSpeech3/KobaSpeech 3 With Vocalizer Serena - English (Great Britain).exe (can work as demo)

So my question is> Is there some way to workaround or solve this issue?

What i tryed:

1. Typical use of Sapi.spvoice object:

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
 
  $spvoice = ObjCreate("sapi.spvoice")
for $voice in $spvoice.getvoices()
  msgbox(0, "Voice", $voice.getdescription())
next

Func MyErrFunc()
$HexNumber = hex($oMyError.number, 8)
Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
SetError(1)
Endfunc


2. Implement workaround based on Nvda Screen reader sapi5 Library at https://github.com/nvaccess/nvda/blob/master/source/synthDrivers/sapi5.py

Thys code in Pascal should work, so i tryed to reproduce it in Autoit.

Pascal code just as example:

             SOTokens:=SpVoice.GetVoices('','');
             for i:=0 to SOTokens.Count-1 do
             try
                  SOToken:=SOTokens.Item(I); s:=SOToken.GetDescription(0);
end

In Autoit I tryed it like this:

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler

  $spvoice = ObjCreate("sapi.spvoice")
for $i = 0 to $spvoice.getvoices.count-1
$name = $spvoice.getvoices.item($i).getdescription
msgbox(0,"Voice", $name)
next

Func MyErrFunc()
$HexNumber = hex($oMyError.number, 8)
Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
SetError(1)
Endfunc

Both of this methods returning same Error ("Member not exists.").

Thanks a lot for help.

Hello @Fenzik

Both examples working for my machine Windows 7 x64.

Check example below and tell me about error. 

Local $oSpvoice = ObjCreate("SApi.SPvoice")
If Not IsObj($oSpvoice) Then ConsoleWrite("+++ Error durning creation object." & @CRLF)

For $voice In $oSpvoice.GetVoices()
  ConsoleWrite($voice.GetDescription() & @CRLF)
Next

#Region COM Event handler.

Local $oMyError = ObjEvent("AutoIt.Error","MyErrFunc") ; run function for verify COM exceptions.

Func MyErrFunc()
    Local $HexNumber = Hex($oMyError.number,8)
    ConsoleWrite("+++ We intercepted a COM Error !"       & @CRLF  & @CRLF & _
             "+++ err.description is: "    & @TAB & $oMyError.description    & @CRLF & _
             "+++ err.windescription:"     & @TAB & $oMyError.windescription & @CRLF & _
             "+++ err.number is: "         & @TAB & $HexNumber              & @CRLF & _
             "+++ err.lastdllerror is: "   & @TAB & $oMyError.lastdllerror   & @CRLF & _
             "+++ err.scriptline is: "     & @TAB & $oMyError.scriptline     & @CRLF & _
             "+++ err.source is: "         & @TAB & $oMyError.source         & @CRLF & _
             "+++ err.helpfile is: "       & @TAB & $oMyError.helpfile       & @CRLF & _
             "+++ err.helpcontext is: "    & @TAB & $oMyError.helpcontext _
            )
    SetError(1)
Endfunc

#EndRegion

My output:

; Output:
; Microsoft Anna - English (United States)
; >Exit code: 0    Time: 0.3973

@Fenzik

The voices count has increased by 1 but not additional parameter Decription is given by KobaSpeech.

Take a look in this example.

Local $oMyError = ObjEvent("AutoIt.Error","MyErrFunc") ; run function for verify COM exceptions.

; Type of speaker:
; 0 - Microsoft Anna - English (United States),
; 1 {on my PC} - KobaSpeech 3 Vocalizer Serena - English (Great Britain)
Local $iVoiceSpeaker = 1

Local $oSpvoice = ObjCreate("SApi.SPvoice")

; Get a new voice speaker
$oSpvoice.Voice() = $oSpvoice.GetVoices().Item($iVoiceSpeaker)

; Say something
$oSpvoice.Speak("Hello Fenzik! Im Serena. Let's works together.",0)


#Region COM Event handler.

Func MyErrFunc()
    Local $HexNumber = Hex($oMyError.number,8)
    ConsoleWrite("+++ We intercepted a COM Error !"       & @CRLF  & @CRLF & _
             "+++ err.description is: "    & @TAB & $oMyError.description    & @CRLF & _
             "+++ err.windescription:"     & @TAB & $oMyError.windescription & @CRLF & _
             "+++ err.number is: "         & @TAB & $HexNumber              & @CRLF & _
             "+++ err.lastdllerror is: "   & @TAB & $oMyError.lastdllerror   & @CRLF & _
             "+++ err.scriptline is: "     & @TAB & $oMyError.scriptline     & @CRLF & _
             "+++ err.source is: "         & @TAB & $oMyError.source         & @CRLF & _
             "+++ err.helpfile is: "       & @TAB & $oMyError.helpfile       & @CRLF & _
             "+++ err.helpcontext is: "    & @TAB & $oMyError.helpcontext _
            )
    SetError(1)
Endfunc

#EndRegion

Ascer,

thank you for your Example.

It's totaly strange, that Koba voices don't provide information about their names by standart way, defined in Sapi SDK.

But in this case i have to know names of voices with i want to work before i list them by the object.

 

So my question is still:

Why other languages (Pascal, Python) can implement retrieving names by index (collection.item($n)) also in this strange case and Autoit Not.

Can this rely for example on given Data Type? I mean that other languages have the types exactly defined.

In Python Sapi Library (Url in First post) this problem is solved also only by fetching object items by their index and it works also for this Buggy Koba.

Koba voices also falls down when using any other methods, for example $voice.gettattribute("name").

So i want to know how way other programs can retrieve this informations (Name etc.) from Sapi object also in this strange cases.

As result i want to retrieve installed voices without knowing their names before only from the sapi object.

It have to work somehow, because developers of other programs using sapi (Balabolka, NVDA) solved this strange behaviour.

      I tried to implement the code in this topic:
      Firstly, i have no idea how these lines of code work but meanwhile i noticed that:
      ; Everytime autoit wants to call a method, get or set a property in a object it needs to go to ; IDispatch::GetIDsFromNames. This is our version of that function, note that by defining this ourselves ; we can fool autoit to believe that the object supports a lot of different properties/methods. Func __IDispatch_GetIDsFromNames($pSelf, $riid, $rgszNames, $cNames, $lcid, $rgDispId) ... EndFunc The problem is i ran into is that some object calls didn't go through IDispatch::GetIDsFromNames.
      Here is the code to replicate what i'm mentioning:
      I followed the example in the topic and tried to do the same thing with method .Documents (line 193) and .Open (line 194) but didn't get the same result because .Documents was being passed through __IDispatch_GetIDsFromNames while .Open didn't.
      $Au3_CallByName = 'Documents' Local $oDoc = $oAppl.Au3_CallByName $Au3_CallByName = 'Open' $oDoc = $oDoc.Au3_CallByName($sFilePath, $bConfirmConversions, $bReadOnly, $bAddToRecentFiles, $sOpenPassword, "", $bRevert, $sWritePassword, "", $iFormat) Console outputs:
      ==> The requested action with this object has failed.: $oDoc = $oDoc.Au3_CallByName($sFilePath, $bConfirmConversions, $bReadOnly, $bAddToRecentFiles, $sOpenPassword, "", $bRevert, $sWritePassword, "", $iFormat) $oDoc = $oDoc^ ERROR Is there any workarounds to solve this?

      Thank you!

      I've made a library, based on AutoItObject UDF with the goal of implementing getter and setter functionality and make it possible to define new object properties in as few steps as possible.
      Thank you to @trancexx for getting me on the right track, and all users in Hooking into the IDispatch interface for the code to get me going.
      If I've forgotten to add credit, please let me know
      Example:
      #include "AutoItObject_Internal.au3" $myCar = IDispatch() $myCar.make = 'Ford' $myCar.model = 'Mustang' $myCar.year = 1969 $myCar.__defineGetter('DisplayCar', DisplayCar) Func DisplayCar($oThis) Return 'A Beautiful ' & $oThis.parent.year & ' ' & $oThis.parent.make & ' ' & $oThis.parent.model EndFunc MsgBox(0, "", $myCar.DisplayCar) More examples: https://github.com/genius257/AutoItObject-Internal/tree/master/Examples
      Version: 3.0.0
      AutoItObject_Internal.au3
      Documentation
      Edit2 (19th March 2017):
      First of all, sorry about the lack of updates on this project. I always start too many projects and end up ignoring old projects, if I run into problems ^^'.
      So I've started moving my AutoIt scripts to GitHub. I will still post the most recent script version here.

      hello autoit team
      please
      i tried to create a SPVoice object 
      when i create the object and tried to use this function SetAlertBoundary
      it gave me an error
      please where is the problem?
      here is the code
      local $o_Sapi_OBJ = ObjCreate("SAPI.SpVoice") if IsObj($o_Sapi_OBJ) then $o_Sapi_OBJ.SetAlertBoundary("SPEI_PHONEME") endIf note i got the function name from microsoft web site

      Hi AutoIt Programmers!

      I've seen a code that gives Name of Group by writing it's group's SID, but this one response very slower than Windows Command-Line WMIC
       
      Func _GetLocalGroupName($sSID = 'S-1-5-18') $objWMIService = ObjGet ("winmgmts:\\" & @ComputerName & "\root\cimv2") $colItems = $objWMIService.ExecQuery('SELECT Name FROM Win32_Group where SID="' & $sSID & '"') For $GroupNames in $colItems MsgBox (0,"",$GroupNames.Name) ExitLoop Next EndFunc I don't want call and use any third-party programs even CMD, i just want use from Windows API, netapi32.dll or AutoIt Functions (Standalone).
      Do you have any idea to improve speed/performance of this code? I'll happy of your comments

      Utter is simply a UDF created for the maximum utilization of SAPI (Speech Recognition API) in windows you can add your own words to be recognized by the computer you can set speed,picth and select the voice you want by speech synthesis included in windows.Utter can create a free grammar recognition engine as well as custom made grammar recognition engine suiting according to your need also it is flexible.The shutdown function of the UDF must be called before calling another one to destroy the current engine running when autoit closes the engine will also close many functionalities are included an update will be soon in future
