ISpVoice::IsUISupported

ISpVoice::IsUISupported checks if the underlying text-to-speech engine's object token supports the requested UI.

<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> <strong>[local] HRESULT IsUISupported(</strong> <strong> const WCHAR</strong> *<em>pszTypeOfUI</em>, <strong> void</strong> *<em>pvExtraData</em>, <strong> ULONG</strong> <em>cbExtraData</em>, <strong> BOOL</strong> *<em>pfSupported</em> <strong>);</strong> </pre>

Parameters

• pszTypeOfUI
  [in] Address of the null-terminated string containing the UI type that is being queried.
• pvExtraData
  [in] Pointer to additional information needed for the object. The TTS Engine implementer dictates the format and usage of the data provided.
• cbExtraData
  [in] Size, in bytes, of the ExtraData. The TTS Engine implementer dictates the format and usage of the data provided.
• pfSupported
  [out] Flag specifying whether the specified UI is supported. TRUE indicates the UI is supported, and FALSE indicates the UI is not supported. ** If this value is TRUE, but the return code is S_FALSE, the UI type (pszTypeOfUI) is supported, but not with the current parameters or run-time environment. Check with the engine implementer to verify run-time requirements.

Return Values

Value	Description
S_OK	Function completed successfully.
S_FALSE	The UI is supported but not with the current run-time environment or parameters.
E_INVALIDARG	One or more parameters are invalid.
FAILED(hr)	Appropriate error message.

Remarks

This method will return S_OK when using Microsoft engines, but the value of pfSupported will be FALSE.
