Microsoft Speech API 5.4

CSpStreamFormat::AssignFormat

CSpStreamFormat::AssignFormat assigns (or copies) the instance's current format to a new format (or a new stream).

Converts the instance's stream format into a wave format structure.

  
    HRESULT AssignFormat(
   SPSTREAMFORMAT   eFormat
);

Parameters

• eFormat
  [in] The requested stream format. Must be a valid SPSTREAMFORMAT value of SPSF_8kHz8BitMono or greater.

Return values

Converts instance's stream format into a cached format. Class member m_pCoMemWaveFormatEx will be NULL if an error occurred.

  
    HRESULT AssignFormat(
   ISpStreamFormat  *pStream
);

Parameters

• pStream
  [in] An ISpStreamFormat object.

Return values

Converts instance's stream format into the specified wave format. Class member m_guidFormatId will be GUID_NULL if an error occurred.

  
    HRESULT AssignFormat(
   const   WAVEFORMATEX   *pWaveFormatEx
);

Parameters

• pWaveFormatEx
  [in] Address of the WAVEFORMATEX structure containing the wave file format information.

Return values

Assigns the instance's format according to a reference GUID and a wave format.

HRESULT AssignFormat(
REFGUID                 rguidFormatId,
   const   WAVEFORMATEX   *pWaveFormatEx
);

Parameters

• rguidFormatId
  [in] The reference ID. If specified as SPDFID_WaveFormatEx, pWaveFormatEx is a WAVEFORMATEX data structure. Otherwise this is set to GUID_NULL.
• pWaveFormatEx
  [in] If rguidFormatId is not set to SPDFID_WaveFormatEx, this is passed back as NULL.

Return values

Assigns (or copies) the instance's stream to a specific stream.

HRESULT AssignFormat(
const   CSpStreamFormat & Src
);

Parameters

• Src
  [out] The stream to copy to.
