Seech SDK 5.1 VC++ question

HI,
I am working with the Speech SDK TTS
I face an error when I want to change the token.

I add this

CComPtr<IEnumSpObjectTokens> cpEnum;
CComPtr<ISpObjectToken> cpToken;

if(SUCCEEDED(hr))
      {
            hr = SpEnumTokens(SPCAT_VOICES, L"Name=Microsoft Sam", NULL, &cpEnum);
      }


      //set the voice
      if(SUCCEEDED(hr))
      {
            hr = cpVoice->SetVoice( cpToken);
      }

      if(SUCCEEDED(hr))
      {
            hr = cpVoice->SetOutput( NULL, TRUE );
      }

it keeps saying 'CComPtr' : undeclared identifier

what;s wrong?

I tried to include #include <atlbase.h> but even worst, it shows over 100 errors.

hi gorexy,

CComPtr can only be use in an ATL environment. So you have to create an Atl Project or use http://www.codeproject.com/com/ccomptr.asp for non Atl project.

You can also use the _com_ptr_t from comip.h (lib: comsupp.lib)

typedef _com_ptr_t<_com_IIID<ISpObjectToken, &__uuidof(ISpObjectToken)> > ISpObjectTokenPtr;
typedef _com_ptr_t<_com_IIID<IEnumSpObjectTokens, &__uuidof(IEnumSpObjectTokens)> > IEnumSpObjectTokensPtr;

_com_ptr_t automatically query to all supported compobjects, if it fail it will set the pointer to 0.

IEnumSpObjectTokensPtr cpEnum;
hr = SpEnumTokens(SPCAT_VOICES, L"Name=Microsoft Sam", NULL, &cpEnum);

Hi thanks!
My code is as follows:

///////////////////////////////////////////////////////////////
#include "CKAll.h"
#include <sapi.h>

.....

int SpeakOut(const CKBehaviorContext& BehContext)
{

      CKBehavior* beh = BehContext.Behavior;

      CComPtr<ISpVoice> cpVoice;

      beh->ActivateInput(0,FALSE);
      beh->ActivateOutput(0);

     char sIP[300];
      beh->GetInputParameterValue(0, sIP);
beh->SetOutputParameterValue(0,sIP);

      TCHAR wsIP[300];
      MultiByteToWideChar(CP_ACP, 0, sIP, -1, (LPWSTR)wsIP, 300);

      //////////////////////////Text to Speech Start/////////////////////////

pVoice->Release();
pVoice = NULL;

Do you mind to have a look and suggest me how to change it?

I will try your code also

sorry I am new in this kind of stuff

ASKER

ok now I try to use the link your provide
and one error only

SpEnumTokens': identifier not found, even with argument-dependent lookup

I search the SDK reference and the function found in #include <sphelper.h>

so I include #include <sphelper.h>

but fail
any suggestion?

for sapi with _com_ptr_t you need:

#include <comip.h> // (comsupp.lib)
#include <sapi.h> //(sapi.lib)
#include <spuihelp.h>

can you post the errormessage please

ups, sorry, you already posted the error

ASKER

that is ok

how to initilize cpVoice

typedef _com_ptr_t<_com_IIID<ISpVoice, &__uuidof(ISpVoice)> > ISpVoice cpVoice;
this is wrong

oh, before you can use cpToken, you have to init or load from enum!

cpEnum->->Item(0, &cpToken );

>typedef _com_ptr_t<_com_IIID<ISpVoice, &__uuidof(ISpVoice)> > ISpVoice cpVoice;
well, this is ok, but its a typedef, this means if you write cpVoice would be the same as to write _com_ptr_t<_com_IIID<ISpVoice, &__uuidof(ISpVoice)> > like #define...

to declare a pointer just write cpVoice pVoice;
But you later used cpVoice directly, but it is a typefef, no variable.

To be more clrear i changed cpVoice to VoicePtr, like the other typedefs

cpEnum->->Item(0, &cpToken ); must be cpEnum->Item(0, &cpToken );

ASKER

i am still testing

once ok i will get back to you

BTW, where can I learn more ATL projecT? I feels confused still
Thanks

i normally don't use ATL...
here you can find some examples:
http://www.codeguru.com/cpp/com-tech/atl/

ASKER

I don't want to use too
but the SPEECH SDK uses that and we have to follow

I want to change the voice freely and so I need to get the token
The SDK example use ATL and so I follow

will let you know it works or not
Thanks for your help!!

im sorry, i forgot to metion:
there are two helpers for sapi, the sphelper.h wich requiers no atl and the spuihelp.h wich requires atl.
within sphelper.h there is also all defined you need like SpEnumTokens...
i thought you were using the sphelper.h, so im sorry for not telling you earlier

The CComPtr than will also work when including sphelper.h

it works

BTW, do you know can we program MS Agent? but I want to hide the characters but can still perform the same TTS as the above code

>unresolved external symbol "void __stdcall _com_issue_error(long)
looks like you forgot to add the comsupp.lib in the project dependencies

sorry, i never used MS Agent...
i only know the ms Agent is using sapi4 for TTS

ASKER

I have to try tmr about the comsupp.lib

so I will try to dig out the MS Agent and try to combine with my code and see it can produce different language or not.

Hope you can still help

well sapi5 does support different languages...
it depends on the voice you are choosing. You also can use the voices of the MS Agent, but than you have to use the sapi4 interface, cuz the voices MS Agent is using are sapi4.
You can get the language code id of a sapi5 voice from its token:

#include <sstream>
#include <algorithm>
typedef long int32;
...

std::vector<int32> getLcids(const ISpObjectTokenPtr& token)
{
// get lcids as string seperated with ";"
ISpDataKeyPtr attrib;
if (token->OpenKey(L"Attributes", &attrib) != S_OK) return std::vector<int32>();
wchar_t * dstr = 0;
std::wstring str;
if (attrib->GetStringValue(L"Language",&dstr) == S_OK)
str= dstr;
CoTaskMemFree(dstr);

// seperate strings and convert to int32
std::vector<int32> ret;
if (str.empty()) return ret;
std::vector<std::wstring> v;
typedef std::wstring::const_iterator iter;

iter i = str.begin();
while (i != str.end()) {

       // ignore leading blanks
       i = find_if(i, str.end(), non_sc);

       // find end of next word
       iter j = find_if(i, str.end(), is_sc);

       // copy the characters in `[i,' `j)'
       if (i != str.end())
v.push_back(std::wstring(i, j));
       i = j;
}

if (v.empty()) return ret;
for (std::vector<std::wstring>::const_iterator iter = v.begin(); iter != v.end(); ++iter)
{
std::wistringstream sstr(*iter);
int32 tmp;
sstr >> std::hex >> tmp;
ret.push_back(tmp);
}
return ret;
}

ASKER

hi
"well sapi5 does support different languages..."
Are you sure? I read the specification of the SDK, and it said for TTS, only supported Simple Chinese and English. That's why I want to use MS Agent.
If so it is a good news, how to do it?

Your code can do so?
let me read first...

ASKER

In my code, I try to get the toketn (ie. get different languages) already but I assume that user installed the TTS Language pack in their computer and so my system contains only English and Simply Chinese TTS which can be found in the registry key.

So you said we SAPI support different language, do we need to install anything? MS Agent?

well,
the default sapi5 languages installed with windows are only english. but there are many tts modules for sapi4/sapi5 from different companys. Most of them not for free (particularly the high quality voices and sapi5 voices). For sapi4 you will get many free voices from the internet (like the one form MS Agent: http://www.microsoft.com/msagent/downloads/user.asp#tts).
If you want to use both, you need a interface that can work with sapi4 and sapi5. In this case you have to write an abstaction layer for the function you need and implement them for the sapi4 and sapi5 interface.

ASKER

oh too complicated to me.

hm...if MS Agent can provide different languages, I prefer to develop the SAPI4
let see how it works...

Do you mind to tell me what is the best way to learn VC++? I found it is quite hard to manage.

ASKER

This is the code from MS Agent
Before I try to modify it, do you think it doesn't load the character and it can still read a text, say from a textbox, and it can pronounce?

just search google or in the expert-exchange database for "lerning c++"

You can try to call the Speak function with hidden character:
...
// don't show the character
//hRes = pCharacterEx->Show(FALSE, &lRequestID);

//if (FAILED(hRes))
// __leave;

// Make the character speak

bszSpeak = SysAllocString(L"Hello World!");

hRes = pCharacterEx->Speak(bszSpeak, NULL, &lRequestID);

SysFreeString(bszSpeak);
...

thanks for your advice for learning C++. C++ is OK but VC++ is hard It added many extra codes

So let me try to combine my code with this MS Agent and see it can work out on differnet languages or not.

I think it should be ok, right? (I don't have strong confidence actually haha)

first try the demo with the hidden character if it is speaking...

ASKER

I don't know why my MS Agent cannot work
The agent jumps out but no sound

and your code is working because it doesn't jump out (but i can see a small icon in the tray, it is ok)
still figure out what happen

ASKER

finally it sounds.

but when I hide the wizard, no sound appears

>unresolved external symbol "void __stdcall _com_issue_error(long)
looks like you forgot to add the comsupp.lib in the project dependencies

This works well now!!! Thanks

I am working on the SAPI4 to different languages
Hope it works
