Speech Automation 5.1
SpeechAudioFormatType Enum
The SpeechAudioFormatType enumeration lists the supported stream formats.
These enumeration elements are all common audio formats ranging from the uncompressed PCM formats to highly compressed formats. They are available as standard formats on the Windows operating systems and are supported by SAPIĀ 5.
