Pamela is the platform’s conversational voice agent, backed by the ElevenLabs text-to-speech API. She handles inbound and outbound call workflows: greeting callers, proposing appointment slots mid-call, booking appointments live, and dispatching outbound follow-up calls for the CRE, MedSpa, and FounderSignal campaigns. Pamela ships in two forms:
  • A voice gateway of REST endpoints that power speech synthesis, slot lookup, mid-call booking, post-call ingestion, and outbound dispatch. See the voice endpoints reference.
  • A web voice widget mounted site-wide that lets visitors hear Pamela answer common questions directly in the browser.

​
Prerequisites

  • An ElevenLabs account with an API key.
  • Optionally, a specific ElevenLabs voice ID to use for Pamela.

​
Configuration

Pamela reads two environment variables:
  • ELEVENLABS_API_KEY is required. If it is unset, POST /api/voice/tts returns HTTP 500 with the error ELEVENLABS_API_KEY is not configured in environment.
  • ELEVENLABS_VOICE_ID_PAMELA is optional. When unset, Pamela falls back to a built-in default voice. A voiceId passed in the request body takes precedence over both.
Speech synthesis defaults to the eleven_multilingual_v2 model and mp3_44100_128 output format. Callers can override the model per request with the modelId body parameter.

​
What Pamela does on a call

  1. Proposes slots. Mid-call, the agent fetches open diagnostic slots from GET /api/voice/slots and offers them to the caller.
  2. Books live. When the caller picks a slot, POST /api/voice/book confirms the appointment and returns a booking reference. Each booking is written to the security audit log.
  3. Reports back. After the call ends, the telephony provider posts the transcript, sentiment, disposition, and recording URL to POST /api/voice/webhook, which logs the call into the Results Vault and CRM.
  4. Dials out. POST /api/voice/dispatch queues an outbound call with a campaign-specific script for CRE, MedSpa, or FounderSignal leads.

​
Web voice widget

The Pamela web voice widget is mounted on every page through the shared page layout. It renders a floating “Talk to Pamela” button in the bottom-right corner of the site. When a visitor opens the widget, they can choose from a set of canonical questions, such as “What is the 15-Minute Diagnostic?” or “How do I schedule a session with Robert?” The widget sends the scripted answer to POST /api/voice/tts and plays the returned MP3 audio in the browser. The widget is zero-cost to operate on the client side. Audio is synthesized on demand by the server, so the only usage cost is the ElevenLabs API calls behind POST /api/voice/tts.

​
Voicemail greeting generator

The repository includes a script, scripts/generate-pamela-voicemail.mjs, that synthesizes Pamela’s Google Voice voicemail greeting as an MP3. Run it with your ElevenLabs credentials in .env.local:
The script writes the greeting to client/public/audio/pamela-google-voice-greeting.mp3 so the site can serve it, plus a copy at the repository root. Upload the MP3 to Google Voice as the voicemail greeting.
To change Pamela’s voice everywhere at once, set ELEVENLABS_VOICE_ID_PAMELA and regenerate the voicemail greeting so the phone greeting matches the web widget.
