Amazon Nova Sonic
A speech-to-speech foundation model for conversational AI
What is Amazon Nova Sonic?
Amazon Nova Sonic delivers real-time, human-like voice conversations with leading price performance and low latency. Available in Amazon Bedrock via the bidirectional streaming API, the model understands streaming speech in various speaking styles and generates expressive speech responses that dynamically adapt to the prosody of input speech.
Amazon Nova Sonic supports expressive voices, including both masculine-sounding and feminine-sounding voices, in English, Spanish, French, Italian, and German. The model can be utilized across a wide range of applications, including customer support call automation, outbound marketing, voice-enabled personal assistants and agents, and interactive education and language learning.

Amazon Nova Sonic enables EF students to practice new vocabulary and refine their pronunciation in a dynamic learning environment. The model is capable of accurately understanding non-native English speakers with a variety of accents. We were also impressed with the barge-in feature of Nova Sonic, where the model quickly reacts to interruptions. The scalability and reliability of the technology will allow us to expand our capacity to serve a larger student population.
