determine a corresponding user intent for one or more of the previous portions of the ongoing conversation between the user and the bot;
cause, based on processing at the least (i) the representation of the utterance received during the ongoing conversation, (ii) the context of the ongoing conversation, and (iii) the corresponding user intent for one or more of the previous portions of the ongoing conversation, a reply by the bot, to the utterance, to be generated; and
cause synthesized speech, that captures the reply by the bot to the utterance, to be provided for audible presentation to the user, the synthesized speech being provided for audible presentation to the user via one or more speakers of a computing device of the user.
8. The system of claim 7 , wherein the context of the ongoing conversation comprises one or more of: a task associated with the conversation, a time the conversation is initiated, or a location associated with the user.
9. The system of claim 8 , wherein the instructions to cause the synthesized speech to be generated comprise instructions to:
process, using a speech synthesizer, the reply by the bot to generate the synthesized speech.
10. The system of claim 7 , wherein the utterance includes a request to perform a task.
11. The system of claim 10 , wherein the instructions further comprise instructions to:
based on the ongoing conversation:
determine whether the task has been completed; and
in response to determining that the task has been completed:
cause the bot to terminate the conversation.
12. The system of claim 11 , wherein the instructions further comprise instructions to:
in response to determining that the task has not been completed:
cause the bot to continue the conversation.
13. A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations, the operations comprising:
receiving audio data of an utterance spoken by a user during a portion of an ongoing conversation between the user and a bot, the audio data being captured by one or more microphones of a computing device of the user;
