hi when i try to execute this code it says Undefined function or variable loadlibrary
can anyone plz help me

[marian nasry]

thanks for this code very much , but i've one question : how can I control the speed of the speech;
please help me

[Wolfgang Garn]

Speed tag: <rate absspeed="5">, relative speed <rate speed="2"> Values are between -10 and +10.
See XML TTS tutorial (http://msdn.microsoft.com/en-us/library/ms717077(VS.85).aspx ) for more information.

I get stuck when loading the speech library.

This program calls MATLAB's loadlibrary function, which in turn calls the function loaddefinedlibrary. At that point, MATLAB hangs. I let it go for a few minutes and then have to force-quit MATLAB from the Task Manager. I don't get an error message, so I am not sure I have the same error as people who do get an error message about not having a module installed.

Any idea how to fix this issue? I guess it is more general than text2speech but am wondering if anyone ran across this error while using the program.

[Jonathan Cofino]

My computer also hangs when I attempt to use the 'text2speech' function. It worked great in MS XP, but not in MS Vista. very odd.

Sorry... I missed a single quote mark.. should read

text2speech (['count backward from' int2str(k) 'by sevens']);

I'm running:
Matlab 7.10.0 (R2010a)
Win 7, 64bit
I get the following message upon running
text2speech('Hello')
??? Error using ==> loadlibrary at 480
There was an error loading the library "C:\Users\charlie\Documents\MATLAB\Sounds\text2speech\wgText2Speech.dll"
C:\Users\charlie\Documents\MATLAB\Sounds\text2speech\wgText2Speech.dll is not a valid Win32 application.

Error in ==> text2speech at 59
    loadlibrary('wgText2Speech','Speak.h');

Caused by:
    Error using ==> loaddefinedlibrary
    C:\Users\charlie\Documents\MATLAB\Sounds\text2speech\wgText2Speech.dll is not a valid Win32 application.

Question: Could you provide the source code to be re-compiled in the 64bit OS?
Thanks!

[Wolfgang Garn]

I have observed that issue as well and provided a new function based on .NET - use "tts('Hello World')" instead of text2speech. The .NET approach is significantly easier than the previous one. Please let me know whether the "emphasise", "silence", etc. features would be useful in the new version.

[susrutha gongalla]

but we need to download the microsoft SAPI first rite..???

[srinu]

How can i store the speech output in .wav format.? Please help.

[Wolfgang Garn]

If you just use the "tts" function, then you should not have to download SAPI - in particular if you use Windows 7 or Vista.
