ISpeechRecoResultDispatch AudioFormat Property (SAPI 5.3)

  • Article

Microsoft Speech API 5.3

Interface: ISpeechRecoResultDispatch

AudioFormat Property

The AudioFormat property gets or sets the audio stream format.

The controlling recognition context must retain the audio portion of the recognition. By default, a recognition context does not retain audio; that is, RecoContext.RetainedAudio is set to SRAONone. Attempts to access this retained audio stream, including references to AudioFormat, cause an SPERR_NO_AUDIO_DATA error. To retain the audio, use ISpeechRecoContext.RetainedAudio passing SRAORetainAudio as the parameter.

Syntax

Get: SpAudioFormat = ISpeechRecoResult.AudioFormat
Set: ISpeechRecoResultDispatch.AudioFormat = SpAudioFormat

Parts

  • ISpeechRecoResultDispatch

  • SpAudioFormat

    Get: The token represents the current audio output device of the voice.
