/**

 *
 * <pre>
 * `StreamingRecognizeResponse` is the only message returned to the client by
 * `StreamingRecognize`. A series of zero or more `StreamingRecognizeResponse`
 * messages are streamed back to the client. If there is no recognizable
 * audio then no messages are streamed back to the client.
 * Here are some examples of `StreamingRecognizeResponse`s that might
 * be returned while processing audio:
 * 1. results { alternatives { transcript: "tube" } stability: 0.01 }
 * 2. results { alternatives { transcript: "to be a" } stability: 0.01 }
 * 3. results { alternatives { transcript: "to be" } stability: 0.9 }
 *    results { alternatives { transcript: " or not to be" } stability: 0.01 }
 * 4. results { alternatives { transcript: "to be or not to be"
 *                             confidence: 0.92 }
 *              alternatives { transcript: "to bee or not to bee" }
 *              is_final: true }
 * 5. results { alternatives { transcript: " that's" } stability: 0.01 }
 * 6. results { alternatives { transcript: " that is" } stability: 0.9 }
 *    results { alternatives { transcript: " the question" } stability: 0.01 }
 * 7. results { alternatives { transcript: " that is the question"
 *                             confidence: 0.98 }
 *              alternatives { transcript: " that was the question" }
 *              is_final: true }
 * Notes:
 * - Only two of the above responses #4 and #7 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`. #3 and #6 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.
 * - In each response, only one of these fields will be set:
 *     `error`,
 *     `speech_event_type`, or
 *     one or more (repeated) `results`.

  /**
   *
   *
   * <pre>
   * `StreamingRecognizeResponse` is the only message returned to the client by
   * `StreamingRecognize`. A series of zero or more `StreamingRecognizeResponse`
   * messages are streamed back to the client. If there is no recognizable
   * audio then no messages are streamed back to the client.
   * Here are some examples of `StreamingRecognizeResponse`s that might
   * be returned while processing audio:
   * 1. results { alternatives { transcript: "tube" } stability: 0.01 }
   * 2. results { alternatives { transcript: "to be a" } stability: 0.01 }
   * 3. results { alternatives { transcript: "to be" } stability: 0.9 }
   *    results { alternatives { transcript: " or not to be" } stability: 0.01 }
   * 4. results { alternatives { transcript: "to be or not to be"
   *                             confidence: 0.92 }
   *              alternatives { transcript: "to bee or not to bee" }
   *              is_final: true }
   * 5. results { alternatives { transcript: " that's" } stability: 0.01 }
   * 6. results { alternatives { transcript: " that is" } stability: 0.9 }
   *    results { alternatives { transcript: " the question" } stability: 0.01 }
   * 7. results { alternatives { transcript: " that is the question"
   *                             confidence: 0.98 }
   *              alternatives { transcript: " that was the question" }
   *              is_final: true }
   * Notes:
   * - Only two of the above responses #4 and #7 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`. #3 and #6 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.
   * - In each response, only one of these fields will be set:
   *     `error`,
   *     `speech_event_type`, or
   *     one or more (repeated) `results`.
   * </pre>
