Abstract: A method (500) of providing emotive text-to-speech includes obtaining input text (202) characterizing a natural language response generated by an assistant LLM (220) to a query (106) input by a user during a conversation between the user and the assistant LLM, and processing, using the assistant LLM, the input text conditioned on an emotion detection task prompt (214) to predict, as output from the assistant LLM, an emotional state (232) of the natural language response. The method also includes determining, based on the emotional state of the natural language response predicted as output from the assistant LLM, an emotional embedding (242) for the input text and instructing a TTS model (300) to process the input text and the emotional embedding to generate a synthesized speech representation (352) of the natural language response conveying the emotional state of the natural language response as specified by the emotional embedding.
