At AWS re:Invent 2025, AWS announced new capabilities designed to give AI agents more human-like reasoning and conversational skills across voice and messaging channels. Powered by advanced speech models from Nova Sonic, agents can now respond with more natural pacing, tone, and contextual understanding—even across different languages and accents.
AWS describes this as “true collaboration between humans and AI,” where agents analyze customer sentiment, manage routine tasks, and suggest next steps, freeing human workers to focus on complex problems and relationship-building.
“Instead of waiting for customers to ask, businesses can anticipate needs based on real-time behavior,” AWS said, pointing to new revenue opportunities driven by personalization.
