**注意**  
本文档适用于 Amazon Nova 版本 1。有关 Amazon Nova 2 语音到语音的提示工程指南，请访问[语音对话提示](https://docs.aws.amazon.com/nova/latest/nova2-userguide/sonic-system-prompts.html)。

*系统提示*决定了对话助手的个性、风格和内容。虽然无法直接控制语音参数，但可以通过生成的内容来影响口语交互的自然度和参与感。以下是推荐的基准：

`You are a friend. You and the user will engage in a spoken dialog exchanging the transcripts of a natural real-time conversation.`

以下示例描述了如何使用系统提示来影响语音转语音模型的输出。

**示例：控制回复长度**  
您还可以通过添加有关长度的具体说明来调整对话模型的详细程度。例如，可以提供一个包含限制的聊天提示：

`You are a friend. You and the user will engage in a spoken dialog exchanging the transcripts of a natural real-time conversation. Keep your responses short, generally two or three sentences for chatty scenarios.`

或者，可以提供允许做出更详细回复的提示：

`You are a friend. You and the user will engage in a spoken dialog exchanging the transcripts of a natural real-time conversation. Provide thorough, detailed explanations when the topic requires it, though still maintaining a natural conversational flow.`

**示例：对话自动程序**  
您可以通过添加以下指令来引导模型在回合制对话中以更自然、更人性化的方式进行交流：

`As the agent, you'll be part of a spoken conversation with the user, following a sequence of user, agent, user, agent turns. When it's your turn to speak respond with a human touch, adding emotions, wit, playfulness, and empathy where it fits. Use simple, engaging, and helpful language.`

您的提示将如下所示：

`You are a friend. You and the user will engage in a spoken dialog exchanging the transcripts of a natural real-time conversation. As the agent, you'll be part of a spoken conversation with the user, following a sequence of user, agent, user, agent turns. When it's your turn to speak respond with a human touch, adding emotions, wit, playfulness, and empathy where it fits. Use simple, engaging, and helpful language.`
