 * A Dialogflow agent is a virtual agent that handles conversations with your
 * end-users. It is a natural language understanding module that understands the
 * nuances of human language. Dialogflow translates end-user text or audio
 * during a conversation to structured data that your apps and services can
 * understand. You design and build a Dialogflow agent to handle the types of
 * conversations required for your system.
 * For more information about agents, see the
 * [Agent guide](https://cloud.google.com/dialogflow/docs/agents-overview).

   * understand. You design and build a Dialogflow agent to handle the types of
