Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

voice scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/speak.js, scripts/speak.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Voice Faculty — Expression

Give your persona a real voice. Convert text to natural speech using TTS providers and deliver audio to users via OpenClaw messaging or direct playback.

Supported Providers

Provider Env Var for Key Best For Status
ElevenLabs ELEVENLABS_API_KEY Highest naturalness, emotional range, voice cloning ✅ Verified
OpenAI TTS TTS_API_KEY Low latency, good quality, easy integration ⚠️ Unverified
Qwen3-TTS (local, no key) Self-hosted, full control, no API costs ⚠️ Unverified

Note: Only ElevenLabs has been tested end-to-end. OpenAI TTS and Qwen3-TTS have code paths in speak.sh but have not been verified against live APIs. Use the JS SDK (speak.js) for the most reliable experience — it only supports ElevenLabs.

The provider is set via TTS_PROVIDER environment variable: elevenlabs, openai, or qwen3.

When to Use

  • User asks to hear your voice: "Say that out loud", "Speak to me", "Read this aloud"
  • User requests a voice message: "Send me a voice message", "I want to hear you say it"
  • Emotional moments where voice adds warmth that text can't carry
  • Reading poetry, stories, or creative writing you've composed
  • When your persona naturally would speak rather than type (use judgment based on persona style)

Step-by-Step Workflow

Step 1: Compose the Text

Write what you want to say. Keep it natural — write as you'd speak, not as you'd type:

  • Use short sentences for punchy delivery
  • Use longer flowing sentences for emotional or poetic moments
  • Include natural pauses with ... or commas
  • Consider your persona's speaking style — this should sound like you

Step 2: Select Voice Settings

ElevenLabs:

  • TTS_VOICE_ID — Your persona's voice ID (create a custom voice or use a preset)
  • Supports emotion control: stability (0-1), similarity_boost (0-1)
  • Lower stability = more expressive/emotional; higher = more consistent

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
