/**
 * <pre>
 * 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.  recognition_event_type: `RECOGNITION_EVENT_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 `MESSAGE_TYPE_TRANSCRIPT`: `transcript` and possibly `is_final`.
 * *  for `MESSAGE_TYPE_END_OF_SINGLE_UTTERANCE`: only `event_type`.
 * </pre>

 * Protobuf type {@code google.cloud.dialogflow.v2.StreamingRecognitionResult}
