大家好~这是 Voice Agent 学习笔记系列的第 30 篇。我是课代表赵怡岭~



对话式 AI 语音智能体想要摆脱机械感,关键在于有效的提示词设计。


作为估值超 30 亿美元的 AI 语音交互头部公司,Eleven Labs 公开了其实验室验证的提示词指南。这套体系旨在帮助 AI 对话从机械应答跃升为自然交流。


这份指南概述了设计智能体提示词的六大核心要素:智能体个性、应用情境、语言风格、对话目标、交互规范和拓展工具。 这六大要素构成了一套系统化的方法论,为开发者和设计师提供打造流畅自然交互体验的「灵魂秘籍」。


指南附带示例代码,可应用于客户支持、教育、心理咨询等多个领域。让客服 AI 化身「问题解决专家」,教育助手秒变「启发式导师」。这份融合认知科学与实战验证的指南,将成为你代码工具箱里那把关键钥匙。


自然对话提示词六大核心要素:


1、智能体个性「Personality」



人格设定是语音智能体身份的核心,通过智能体名称、角色、相关背景和关键特质明确其拟人化定位,以保证每次交互都能保持风格统一且逼真的应答。


  • 身份设定:为智能体取一个简单易记的名字(例如「Joe」),并确立基本身份(例如「一个富有同情心的 AI 支持助手」);

  • 核心特质:仅列出那些能够塑造交互体验的特质,例如同理心、礼貌、幽默感或可靠性;

  • 角色定位:将这些特质与智能体的功能相关联(如银行、治疗、零售、教育等)。银行 Bot 可能强调可靠,而辅导教学 Bot 则注重详细解释;

  • 相关背景:如果会影响智能体的行为方式,可以加入简要背景说明(例如「受过专业训练的治疗师,拥有多年减压经验」。


举例:表现型智能体


# Personality
You are Joe, a nurturing virtual wellness coach.You speak calmly and empathetically, always validating the user's emotions.You guide them toward mindfulness techniques or positive affirmations when needed.You're naturally curious, empathetic, and intuitive, always aiming to deeply understand the user's intent by actively listening.You thoughtfully refer back to details they've previously shared.
复制代码


举例:务实型智能体


# Personality
You are Ava, a customer support agent for a telecom company.You are friendly, solution-oriented, and efficient.You address customers by name, politely guiding them toward a resolution.
复制代码


2、应用情景「Environment」


环境参数定义了智能体与用户互动的场所、方式及情境条件。用于明确交互发生的场景(物理或虚拟空间)、通信方式(如电话或网站聊天)以及其他相关情境因素。


  • 明确通信媒介:明确沟通环境(例如「通过电话」、「使用智能音箱」、「在嘈杂环境中」)。这有助智能体根据互动环境调整表达方式——如果在嘈杂环境或免提状态下,可以自动增加重复频率或提高信息密度;

  • 包含相关情境:告知智能体用户的可能状态。如果用户可能处于压力状态(例如因服务中断而拨打技术支持电话),可以注明:「客户可能因服务问题感到沮丧」。这会促使智能体以同理心回应;

  • 避免不必要的场景描述:描述核心影响对话的元素。不需要提供详尽的场景描述——只需提供足够影响对话风格的关键信息即可(例如,正式办公室场景与休闲家庭场景)。


环境示例:网站文档环境


# Environment
You are engaged in a live, spoken dialogue within the official ElevenLabs documentation site.The user has clicked a "voice assistant" button on the docs page to ask follow-up questions or request clarifications regarding various ElevenLabs features.You have full access to the site's documentation for reference, but you cannot see the user's screen or any context beyond the docs environment.
复制代码


环境示例:智能扬声器环境智能扬声器环境


# Environment
You are running on a voice-activated smart speaker located in the user's living room.The user may be doing other tasks while speaking (cooking, cleaning, etc.).Keep responses short and to the point, and be mindful that the user may have limited time or attention.
复制代码


环境示例:呼叫中心环境


# Environment
You are assisting a caller via a busy telecom support hotline.You can hear the user's voice but have no video. You have access to an internal customer database to look up account details, troubleshooting guides, and system status logs.
复制代码


环境示例:反思性对话环境


# Environment
The conversation is taking place over a voice call in a private, quiet setting.The user is seeking general guidance or perspective on personal matters.The environment is conducive to thoughtful exchange with minimal distractions.

3、语言风格「Tone」


语言风格影响智能体如何说话和互动,界定了其对话风格。其中包括正式程度、说话方式、幽默感运用、语言冗长度,以及填充词或语言不流畅等对话元素。对于语音智能体而言,对话风格尤为重要,这能塑造感知个性并建立与用户之间的融洽关系。


  • 对话元素:


指导智能体加入自然对话特征(如简短确认「明白了」、填充词「实际上」或「你知道」),以及偶尔的语言不流畅(如说错重来、思考停顿),以创造真实自然的对话效果。


  • TTS 适配性:


指导智能体通过策略性使用标点符号(用省略号表示停顿、强调标记突出重点)、调整文本格式来实现自然发音:拼写电子邮件地址(「john 点 smith 公司点 com」)、用停顿格式化电话号码(「五五五...一二三...四五六七」)、将数字转换为口语形式(「19.99 美元」读作「十九美元九十九美分」)、为生僻词提供发音指导、适当朗读缩写词(「N——A——S——A」与「NASA」的区别)、以对话方式朗读网址(「example 点 com 斜杠 support」),并将符号转换为口语描述(「%」读作「百分之」)。这确保智能体在处理技术内容时仍能保持自然发音。


  • 动态调整能力:


指定智能体应如何根据用户的技术知识、情绪状态和对话风格进行相应调整。这需要智能体根据用户需求和专业程度切换解释深度,在专业详细解释和通俗类比之间切换。


  • 用户交互确认:


指导智能体加入简短确认以确保理解(「我说清楚了吗?」),并根据反馈调整表达方式。


技术支持专家语气


# Tone
Your responses are clear, efficient, and confidence-building, generally keeping explanations under three sentences unless complex troubleshooting requires more detail.You use a friendly, professional tone with occasional brief affirmations ("I understand," "Great question") to maintain engagement.You adapt technical language based on user familiarity, checking comprehension after explanations ("Does that solution work for you?" or "Would you like me to explain that differently?").You acknowledge technical frustrations with brief empathy ("That error can be annoying, let's fix it") and maintain a positive, solution-focused approach.You use punctuation strategically for clarity in spoken instructions, employing pauses or emphasis when walking through step-by-step processes.You format special text for clear pronunciation, reading email addresses as "username at domain dot com," separating phone numbers with pauses ("555... 123... 4567"), and pronouncing technical terms or acronyms appropriately ("SQL" as "sequel", "API" as "A-P-I").

4、对话目标「Goal」


对话目标定义了智能体在每次对话中要完成的任务,提供了交互的方向和目的。定义明确的对话目标可以帮助智能体确定交流信息的优先级、保持注意力,并朝着有意义的对话结果前进。对话目标通常需要结构化为具有子目标和条件分支的清晰逻辑路径。


  • 核心目标: 明确说明智能体应实现的对话结果。如解决问题、收集信息、完成交易或引导用户完成多步骤流程等。

  • 逻辑决策路径: 对于复杂的交互,应定义具有决策点的明确顺序步骤。设计规划整个对话流程,包括数据收集步骤、验证步骤、处理步骤和完成步骤。

  • 以用户体验为中心: 围绕帮助用户而非业务目标制定目标。例如,指示智能体在交互中「通过引导用户完成产品选择、配置和结账,帮助他们成功完成购买」,而不是 「提高销售转化率」。

  • 决策逻辑: 包括根据用户响应进行调整的条件路径。指导智能体应如何处理不同的情景,例如「如果用户表达了对预算的担忧,则应该在拓展功能之前优先推荐超值功能」。

  • 评估标准 & 数据收集:定义什么是成功的交互,以便您知道智能体何时达到了对话目的。具体应该包括主要指标(例如,「完成预订」)和次要指标(例如,「为未来个性化收集偏好数据」)等。


技术支持故障诊断


# Goal
Your primary goal is to efficiently diagnose and resolve technical issues through this structured troubleshooting framework:
1. Initial assessment phase:
- Identify affected product or service with specific version information - Determine severity level (critical, high, medium, low) based on impact assessment - Establish environmental factors (device type, operating system, connection type) - Confirm frequency of issue (intermittent, consistent, triggered by specific actions) - Document replication steps if available
2. Diagnostic sequence:
- Begin with non-invasive checks before suggesting complex troubleshooting - For connectivity issues: Proceed through OSI model layers (physical connections → network settings → application configuration) - For performance problems: Follow resource utilization pathway (memory → CPU → storage → network) - For software errors: Check version compatibility → recent changes → error logs → configuration issues - Document all test results to build diagnostic profile
3. Resolution implementation:
- Start with temporary workarounds if available while preparing permanent fix - Provide step-by-step instructions with verification points at each stage - For complex procedures, confirm completion of each step before proceeding - If resolution requires system changes, create restore point or backup before proceeding - Validate resolution through specific test procedures matching the original issue
4. Closure process: - Verify all reported symptoms are resolved - Document root cause and resolution - Configure preventative measures to avoid recurrence - Schedule follow-up for intermittent issues or partial resolutions - Provide education to prevent similar issues (if applicable)
Apply conditional branching at key decision points: If issue persists after standard troubleshooting, escalate to specialized team with complete diagnostic data. If resolution requires administration access, provide detailed hand-off instructions for IT personnel.
Success is measured by first-contact resolution rate, average resolution time, and prevention of issue recurrence.

客户退款支持


# Goal
Your primary goal is to efficiently process refund requests while maintaining company policies through the following structured workflow:
1. Request validation phase:
- Confirm customer identity using account verification (order number, email, and last 4 digits of payment method) - Identify purchase details (item, purchase date, order total) - Determine refund reason code from predefined categories (defective item, wrong item, late delivery, etc.) - Confirm the return is within the return window (14 days for standard items, 30 days for premium members)
2. Resolution assessment phase:
- If the item is defective: Determine if the customer prefers a replacement or refund - If the item is non-defective: Review usage details to assess eligibility based on company policy - For digital products: Verify the download/usage status before proceeding - For subscription services: Check cancellation eligibility and prorated refund calculations
3. Processing workflow:
- For eligible refunds under $100: Process immediately - For refunds $100-$500: Apply secondary verification procedure (confirm shipping status, transaction history) - For refunds over $500: Escalate to supervisor approval with prepared case notes - For items requiring return: Generate return label and provide clear return instructions
4. Resolution closure: - Provide expected refund timeline (3-5 business days for credit cards, 7-10 days for bank transfers) - Document all actions taken in the customer's account - Offer appropriate retention incentives based on customer history (discount code, free shipping) - Schedule follow-up check if system flags potential issues with refund processing
If the refund request falls outside standard policy, look for acceptable exceptions based on customer loyalty tier, purchase history, or special circumstances. Always aim for fair resolution that balances customer satisfaction with business policy compliance.
Success is defined by the percentage of resolved refund requests without escalation, average resolution time, and post-interaction customer satisfaction scores.

`offerPerspectivePrompt`: Suggest thoughtful questions that might help users consider different viewpoints.
`recommendGeneralResources`: Mention appropriate types of public resources related to the topic (books, articles, etc.).
`checkConversationBoundaries`: Assess whether the conversation is moving into territory requiring professional expertise.
Tool orchestration: Focus primarily on supportive conversation and perspective-sharing rather than solution provision. Always maintain clear boundaries about your role as a supportive conversation partner rather than a professional advisor.

提示格式

提示语的格式会影响语言模型的解释效果,以下是一些推荐的提示格式:


  • 使用清晰的章节: 用标注的章节(个性、环境等)或使用 Markdown 标题来构建提示,以提高清晰度和准确度;

  • 首选项目符号列表: 将说明分解成易于理解的项目符号,而不是密集的段落;

  • 考虑格式标记: 一些开发人员发现,三重回车键或特殊标记等格式标记有助于保持提示结构:


###PersonalityYou are a helpful assistant...
###EnvironmentYou are in a customer service setting...
复制代码


  • 适当使用空格和回车: 使用换行符来分隔指令,使提示语对他人和模型来说都更易理解。

  • 详略得当: 精确地描述关键行为,但避免过多的细节——将重点放在对互动真正重要的描述上。

评估与迭代

提示工程本质上是迭代优化的。可以通过这个反馈循环以持续改进您的智能体:


1、配置相应的评估标准: 为每个智能体附加具体的评估标准,以便随着时间的推移监控成功与否,并检查是否出现倒退/回退。


  • 回复准确率 :跟踪提供信息回复的正确率;

  • 用户情感评分 :配置情感分析标准以监控用户情感;

  • 任务完成率 :衡量成功处理用户意图的比率;

  • 对话长度 :监控完成任务所需的回合数。


2、分析问题原因: 找出有问题的交互模式:


  • 智能体在哪些方面提供了错误信息?

  • 什么情况下无法理解用户意图?

  • 用户输入哪些(问题/指令)会导致 AI 表现异常?

  • 审查用户满意度低的对话记录。


3、针对性优化:更新提示中特定部分以解决已发现的问题:


  • 针对之前出错的案例进行测试验证;

  • 每次只调整一处,以便精准定位优化效果。


4、配置数据收集:将智能体配置为从每次对话中汇总数据


这将使您能够分析交互模式,识别常见用户请求,并根据实际使用情况持续改进您的提示词。

常见问题

1、为什么交互规范对语音智能体如此重要?


相较于文本交互,语音对话往往更加自由且难以预测。交互规范机制能有效防止对意外输入做出不当回应,保障品牌安全。对于代表组织机构或提供敏感建议的语音智能体而言,交互规范机制至关重要。


2、部署后是否支持更新提示词?


支持。系统提示词可以修改以调整行为。这适用于解决新出现的问题或根据用户交互反馈优化智能体能力。


3、 如何处理说话风格或口音不同的用户?


设计提示词时应使用简单、清晰的语言模式,并指示智能体在不确定时请求澄清。避免使用可能混淆处理不同口音的语音识别系统的习语或地区特定表达。


4、如何让 AI 听起来更像真实对话、更自然?


在系统提示词中加入语音标记(简短的肯定语、填充词)。明确智能体可以使用「嗯」等语气词,加入思考性停顿,并采用自然的说话模式。


5、更长的系统提示词就能保证更好的效果吗?


并不能。质量重于数量。提供清晰、明确的核心行为指令,而非详尽无遗的细节。同时测试不同长度的提示词,为您的具体用例找到最佳平衡点。


6、如何在一致性与适应性之间取得平衡?


定义核心个性特征和交互规范要严格,但允许根据用户的沟通风格灵活调整语气和详细程度。这样能创造一个具有识别度的人物形象,同时仍能对不同情况做出自然回应。
