I am using SAPI to make a voice speak text. The error code returned is 

-2147024888

The method "Speak" for 'ISpeechVoice' failed

However I was unable to find this error code on Google. I am not sure why. Does anybody have any ideas? I expected Microsoft to list all possible error codes for SAPI. On the page http://msdn.microsoft.com/en-us/library/ms717306%28v=vs.85%29.aspx this error code is not there.

Thank you for any help!

The SAPI error code listings are for the error codes specific to SAPI. Other errors could be returned.

-2147024888 is equivalent to 0x80070008, which is a Win32 HRESULT (E_OUTOFMEMORY); the call is failing because something (either inside the TTS engine or in SAPI) is not able to allocate enough memory.
