System role adaptation
Note
This documentation is for Amazon Nova Version 1. For the Amazon Nova 2 Speech-to-Speech prompt engineering guide, visit Voice conversation prompts.
Amazon Nova text models benefit from clear role definitions. For Amazon Nova Sonic applications, consider the following:
Define roles that sound natural when speaking (such as, "friendly advisor" rather than "information retrieval system").
Use role descriptions that emphasize conversational attributes (warm, patient, concise) rather than text-oriented attributes (detailed, comprehensive, systematic).
Consider how the chosen voice might influence the perceived personality. Test the voices to chose the best voice for your use case. Review the System prompt authoring guidelines and examples section for techniques on how to indirectly influence the model's natural prosody.
