Announcing Amazon Nova Sonic, a new speech-to-speech model that brings real-time voice conversations to Amazon Bedrock

Amazon has introduced Amazon Nova Sonic, a foundation model that combines speech understanding and generation into one model, enabling human-like voice conversations in AI applications. This model allows developers to build real-time conversational AI applications in Amazon Bedrock with industry-leading price performance and low latency. Amazon Nova Sonic can understand speech in different speaking styles and generate speech in expressive voices, including masculine and feminine voices, in American and British English accents. The model's novel architecture can adapt the intonation, prosody, and style of the generated speech response to align with the context and content of the speech input. Additionally, it allows for function calling and knowledge grounding with enterprise data using Retrieval-Augmented Generation. Amazon Nova Sonic is developed with responsible AI in mind, featuring built-in protections including content moderation and watermarking. To support developers, AWS is launching a new bidirectional streaming API in Amazon Bedrock, enabling two-way streaming of content for low-latency interactive communication. Amazon Nova Sonic can be used to voice-enable various applications, including customer service call automation, outbound marketing, voice-enabled personal assistants, and interactive education. The model is now available in Amazon Bedrock in the US East (N. Virginia) AWS Region. Developers can learn more and get started with Amazon Nova Sonic through the AWS News Blog, product page, user guide, and Amazon Bedrock console.
