Invalid audio format for CRRBuffer CAFDefault StartRecording requests

The information in this article applies to:

• SpeechKit 4

Symptoms

Invoking StartRecording with the CRRBuffer and CAFDefault options for retaining audio from speech recognition returns audio buffers properly. However, how do you know what the recognizer's default audio format is?

Cause

Each recognizer (and speech API) has its own architecture for handling audio. The ChantSR object works within each architecture to provide the most flexibility in obtaining audio from recognition results.

Status

The ChantSREvent Flags property is set to the ChantAudioFormat enumeration constant for the audio type for all CRRBuffer callback events and the ChantTTSEvent Flags property is set to the ChantAudioFormat enumeration constant for the audio type for all CPRBuffer callback events in 4.0.124.0.

Component Formats Impacted

All component formats.
