/**

 *
 * <pre>
 * The top-level message returned from the `StreamingAnalyzeContent` method.
 * Multiple response messages can be returned in order:
 * 1.  If the input was set to streaming audio, the first one or more messages
 *     contain `recognition_result`. Each `recognition_result` represents a more
 *     complete transcript of what the user said. The last `recognition_result`
 *     has `is_final` set to `true`.
 * 2.  In virtual agent stage: if `enable_partial_automated_agent_reply` is
 *     true, the following N (currently 1 &lt;= N &lt;= 4) messages
 *     contain `automated_agent_reply` and optionally `reply_audio`
 *     returned by the virtual agent. The first (N-1)
 *     `automated_agent_reply`s will have `automated_agent_reply_type` set to
 *     `PARTIAL`. The last `automated_agent_reply` has
 *     `automated_agent_reply_type` set to `FINAL`.
 *     If `enable_partial_automated_agent_reply` is not enabled, response stream
 *     only contains the final reply.
 *     In human assist stage: the following N (N &gt;= 1) messages contain
 *     `human_agent_suggestion_results`, `end_user_suggestion_results` or
 *     `message`.
