What This Skill Does

The voice-agent-builder skill provides a comprehensive toolkit for developers and business owners to create, deploy, and manage conversational AI voice agents. By integrating with leading platforms like Vapi, Bland.ai, and Retell, this skill abstracts away the complex infrastructure required for telephony, STT (Speech-to-Text), and TTS (Text-to-Speech). It empowers you to build sophisticated IVR systems, automated appointment setters, and outbound sales agents directly from your terminal.

Installation

To integrate this capability into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/aiwithabidi/voice-agent-pro

Ensure you have your API keys for your chosen provider (Vapi, Bland, or Retell) exported in your shell environment as environment variables before attempting to initialize or trigger agent creation scripts.

Use Cases

• Customer Service: Automate high-volume support inquiries with 24/7 availability.
• Sales & Outreach: Execute personalized outbound calling campaigns for lead qualification.
• Appointment Scheduling: Manage calendars for clinics or businesses by integrating agent responses with backend CRM booking APIs.
• Emergency Alerts: Automate critical outbound notifications that require immediate human acknowledgement.
• Language Practice: Develop language learning bots that provide real-time conversational feedback.

Example Prompts

1. "Build a sales agent named 'Prospector' that uses GPT-4o, has a professional tone, and is configured to use an ElevenLabs voice for outbound calls to our lead list."
2. "Create a summary report of all completed calls from the 'Appointment Setter' agent created last week, including transcriptions and customer sentiment analysis."
3. "List all current phone numbers assigned to my Vapi account and update the system prompt for the primary support agent to emphasize our new refund policy."

Tips & Limitations

• Latency Management: Voice agents rely on network stability. If you require sub-500ms response times, prioritize platforms like Retell or Bland.ai over Vapi's default configurations.
• Prompt Length: Always keep your system prompts concise. Voice latency scales with token count; long prompts result in longer 'thinking' pauses that annoy users.
• Interruptibility: Ensure your agent configuration allows for 'barge-in,' which enables users to interrupt the AI during its speech to keep the conversation feeling natural.
• Compliance: Always ensure your outbound calling strategy complies with local telecommunications regulations, such as the TCPA in the United States.
