 *
 * <pre>
 * `StreamingRecognizeResponse` is the only message returned to the client by
 * `StreamingRecognize`. A series of one or more `StreamingRecognizeResponse`
 * messages are streamed back to the client.
 * Here's an example of a series of ten `StreamingRecognizeResponse`s that might
 * be returned while processing audio:
 * 1. endpointer_type: START_OF_SPEECH
 * 2. results { alternatives { transcript: "tube" } stability: 0.01 }
 *    result_index: 0
 * 3. results { alternatives { transcript: "to be a" } stability: 0.01 }
 *    result_index: 0
 * 4. results { alternatives { transcript: "to be" } stability: 0.9 }
 *    results { alternatives { transcript: " or not to be" } stability: 0.01 }
 *    result_index: 0
 * 5. results { alternatives { transcript: "to be or not to be"
 *                             confidence: 0.92 }
 *              alternatives { transcript: "to bee or not to bee" }
 *              is_final: true }
 *    result_index: 0
 * 6. results { alternatives { transcript: " that's" } stability: 0.01 }
 *    result_index: 1
 * 7. results { alternatives { transcript: " that is" } stability: 0.9 }
 *    results { alternatives { transcript: " the question" } stability: 0.01 }
 *    result_index: 1
 * 8. endpointer_type: END_OF_SPEECH
 * 9. results { alternatives { transcript: " that is the question"
 *                             confidence: 0.98 }
 *              alternatives { transcript: " that was the question" }
 *              is_final: true }
 *    result_index: 1
 * 10. endpointer_type: END_OF_AUDIO
 * Notes:
 * - Only two of the above responses #5 and #9 contain final results, they are
 *   indicated by `is_final: true`. Concatenating these together generates the
 *   full transcript: "to be or not to be that is the question".
 * - The others contain interim `results`. #4 and #7 contain two interim
 *   `results`, the first portion has a high stability and is less likely to
 *   change, the second portion has a low stability and is very likely to
 *   change. A UI designer might choose to show only high stability `results`.
 * - The specific `stability` and `confidence` values shown above are only for
 *   illustrative purposes. Actual values may vary.
 * - The `result_index` indicates the portion of audio that has had final
 *   results returned, and is no longer being processed. For example, the
 *   `results` in #6 and later correspond to the portion of audio after
 *   "to be or not to be".

  /**
   *
   *
   * <pre>
   * `StreamingRecognizeResponse` is the only message returned to the client by
   * `StreamingRecognize`. A series of one or more `StreamingRecognizeResponse`
   * messages are streamed back to the client.
   * Here's an example of a series of ten `StreamingRecognizeResponse`s that might
   * be returned while processing audio:
   * 1. endpointer_type: START_OF_SPEECH
   * 2. results { alternatives { transcript: "tube" } stability: 0.01 }
   *    result_index: 0
   * 3. results { alternatives { transcript: "to be a" } stability: 0.01 }
   *    result_index: 0
   * 4. results { alternatives { transcript: "to be" } stability: 0.9 }
   *    results { alternatives { transcript: " or not to be" } stability: 0.01 }
   *    result_index: 0
   * 5. results { alternatives { transcript: "to be or not to be"
   *                             confidence: 0.92 }
   *              alternatives { transcript: "to bee or not to bee" }
   *              is_final: true }
   *    result_index: 0
   * 6. results { alternatives { transcript: " that's" } stability: 0.01 }
   *    result_index: 1
   * 7. results { alternatives { transcript: " that is" } stability: 0.9 }
   *    results { alternatives { transcript: " the question" } stability: 0.01 }
   *    result_index: 1
   * 8. endpointer_type: END_OF_SPEECH
   * 9. results { alternatives { transcript: " that is the question"
   *                             confidence: 0.98 }
   *              alternatives { transcript: " that was the question" }
   *              is_final: true }
   *    result_index: 1
   * 10. endpointer_type: END_OF_AUDIO
   * Notes:
   * - Only two of the above responses #5 and #9 contain final results, they are
   *   indicated by `is_final: true`. Concatenating these together generates the
   *   full transcript: "to be or not to be that is the question".
   * - The others contain interim `results`. #4 and #7 contain two interim
   *   `results`, the first portion has a high stability and is less likely to
   *   change, the second portion has a low stability and is very likely to
   *   change. A UI designer might choose to show only high stability `results`.
   * - The specific `stability` and `confidence` values shown above are only for
   *   illustrative purposes. Actual values may vary.
   * - The `result_index` indicates the portion of audio that has had final
   *   results returned, and is no longer being processed. For example, the
   *   `results` in #6 and later correspond to the portion of audio after
   *   "to be or not to be".
   * </pre>
