SAPI_UseNativeAudioObj

Property SAPI_UseNativeAudioObj As Boolean
Read/Write: Read and Write

Description

Enable or disable using the native audio object in TTS or SR modules of SAPI 5.1.

Remarks

Default value of SAPI_UseNativeAudioObj is true.

The native audio object of SAPI 5.1 (ISpMMSysAudio) supports PCM wave format only. But some telephony devices such as Dialogic ProLine/2V,D/41E,D/41ESC,D/21D,D/41D,D/21H,D/41H don't support PCM (it support u-LAW only), so those devices MUST set SAPI_UseNativeAudioObj false to perform TTS or SR.
