Class StreamingRecognitionResult (3.5.0) 

public sealed class StreamingRecognitionResult : IMessage<StreamingRecognitionResult>, IEquatable<StreamingRecognitionResult>, IDeepCloneable<StreamingRecognitionResult>, IBufferMessage, IMessage

Contains a speech recognition result corresponding to a portion of the audio that is currently being processed or an indication that this is the end of the single requested utterance.

Example:

  1. transcript: "tube"

  2. transcript: "to be a"

  3. transcript: "to be"

  4. transcript: "to be or not to be" is_final: true

  5. transcript: " that's"

  6. transcript: " that is"

  7. message_type: END_OF_SINGLE_UTTERANCE

  8. transcript: " that is the question" is_final: true

Only two of the responses contain final results (#4 and #8 indicated by is_final: true). Concatenating these generates the full transcript: "to be or not to be that is the question".

In each response we populate:

  • for TRANSCRIPT: transcript and possibly is_final.

  • for END_OF_SINGLE_UTTERANCE: only message_type.
