Introducing Amazon Nova 2 Sonic: Our new speech-to-speech model for conversational AI

Amazon launched Nova 2 Sonic, an advanced speech-to-speech AI model that enables natural, real-time voice conversations. The upgraded model features enhanced intelligence, expanded language support including Portuguese and Hindi, polyglot voices that can switch languages mid-conversation, and improved speech recognition for accents and background noise. Key capabilities include seamless text-to-voice switching, asynchronous tool calling for complex tasks, and direct integration with major telephony providers like Twilio and Amazon Connect, making it easier for developers to deploy conversational AI across phone systems and global applications.
