Amazon Nova 2 Sonic
Amazon Nova 2 Sonic is a proprietary Amazon foundation model. A speech-to-speech dialogue model that integrates spoken understanding and response generation for natural conversation. It supports multilingual interactions, tool integration, and turn-taking behavior for real-time voice applications. It is distinct from a transcription-only service. March and May 2026 updates refresh the same serving model rather than introducing a separately named generation. Amazon has not published the model’s parameter count or detailed network architecture. Responses can contain unsupported claims, and preview/service availability varies by region and customer access.
