Specifying trip destinations from spoken dialogs

A system for determining a destination, comprising one or more processors and one or more non-transitory computer-readable memories coupled to the one or more processors and configured with instructions executable by the one or more processors to cause the system to perform operations comprising:

• receiving a user speech input through a voice user interface;
• obtaining a plurality of current utterance variables by tokenizing the user speech input;
• determining, by a trained automatic agent, one or more of a plurality of utterance templates for a reply to the user speech input based on the plurality of current utterance variables;
• determining, by the trained automatic agent based on the plurality of current utterance variables, one of a plurality of Application Programming Interfaces (API) to call and one or more parameters for the API to call with, wherein the one or more parameters are based on information of the plurality of current utterance variables;
• obtaining a response from the API call;
• and
• constructing a context string for the reply to the user speech input by the trained automatic agent based on the one or more of the plurality of utterance template and the response of the API call.
