Synthesized speech audio data generated on behalf of human participant in conversation

A system comprising:

• at least one processor;
• and
• memory storing instructions that, when executed, cause the at least one processor to be operable to:
• receive, via a client device of a user, audio data that captures a spoken utterance of an additional user, the spoken utterance being provided by the additional user as part of a conversation between the user and the additional user;
• generate, based on processing the audio data that captures the spoken utterance of the additional user, one or more suggestions, each of the one or more suggestions including a corresponding textual segment that is responsive to the spoken utterance;
• determine a set of prosodic properties, from among a plurality of disparate sets of prosodic properties, to be utilized in generating synthesized speech audio data that includes synthesized speech corresponding to a given suggestion of the one or more suggestions;
• generate, using the set of prosodic properties, the synthesized speech audio data that includes synthesized speech corresponding to the given suggestion of the one or more suggestions;
• and
• cause the synthesized speech audio data to be rendered as part of the conversation between the user and the additional user.
