**Note**  
This documentation is for Amazon Nova Version 1. For the Amazon Nova 2 Speech-to-Speech prompt engineering guide, visit [Voice conversation prompts](https://docs.aws.amazon.com/nova/latest/nova2-userguide/sonic-system-prompts.html).

When you create prompts for Amazon Nova Sonic, we recommend that you avoid the following:
+ Visual formatting like bullet points, tables, or code blocks.
+ Voice characteristic modifications like accent, age, or singing.
+ Sound effects or extensive onomatopoeia.
+ Content that relies on being seen rather than being heard.
