tomevault-io Speak
Announce plans, issues, and summaries aloud using project-specific voices. Triggered automatically after major milestones.
When to Announce
Announce automatically after:
- Planning complete - When a plan/todo list is finalized
- Issue resolved - When a bug fix or error is resolved
- Summary generated - When completing a sprint or major task
Configuration
Store config at .claude/tts-config.json in the project root:
{
"provider_order": ["google", "openai", "elevenlabs", "say"],
"unavailable_providers": [],
"voices": {
"planning": { "provider": "google", "voice": "Kore", "style": "calm" },
"issue": { "provider": "google", "voice": "Aoede", "style": "urgent" },
"summary": { "provider": "google", "voice": "Charon", "style": "satisfied" }
},
"assigned_at": "2025-01-15T10:30:00Z"
}
On first use in a new project, auto-generate config by selecting unused voices from the voice pool (see references/voice-pools.json).
Note: say (macOS) requires no API key and should always work as final fallback.
Workflow
- Detect message type - planning, issue, or summary
- Load config - Read
.claude/tts-config.jsonor create if missing - Select provider - Use first provider from
provider_ordernot inunavailable_providers - Transform text - Convert to speech-friendly format (see below)
- Speak - Call appropriate TTS tool with configured voice
- Handle failures - See error handling below
Error Handling
When a TTS call fails, check the error type:
| Error Pattern | Action |
|---|---|
| "API key", "unauthorized", "authentication", "GOOGLE_API_KEY", "OPENAI_API_KEY", "ELEVENLABS_API_KEY" | Add provider to unavailable_providers, save config, try next |
| "rate limit", "quota", "429" | Try next provider (temporary) |
| Other errors | Try next provider |
Critical: On auth/config errors, immediately update .claude/tts-config.json to add the provider to unavailable_providers. This persists across sessions and prevents wasted attempts.
Example after Google fails due to missing API key:
{
"provider_order": ["google", "openai", "elevenlabs", "say"],
"unavailable_providers": ["google"],
...
}
The agent will now skip Google and start with OpenAI on next announcement.
Text Transformation
Convert verbose output to conversational speech:
| Remove/Replace | With |
|---|---|
| URLs | "see the link" or omit |
| Code blocks | "see the code changes" or brief description |
| File paths | Just the filename (e.g., /src/lib/foo.rs -> "foo.rs") |
| Long hashes/IDs | "a commit hash" or omit |
| Long number lists | "several values" or count |
| Markdown formatting | Plain text |
| Technical jargon | Simpler alternatives when possible |
Target length: ~15-30 seconds of speech (roughly 50-100 words)
Tone by type:
- Planning: "Here's the plan..." (forward-looking, organized)
- Issue: "Found a problem..." (alert but calm)
- Summary: "All done..." (satisfied, accomplished)
TTS Tools
google_tts (preferred)
mcp__mcp-tts__google_tts
- text: string (required)
- voice: string (default: "Kore")
- model: string (default: "gemini-2.5-flash-preview-tts")
Voices: Achernar, Achird, Algenib, Algieba, Alnilam, Aoede, Autonoe, Callirrhoe, Charon, Despina, Enceladus, Erinome, Fenrir, Gacrux, Iapetus, Kore, Laomedeia, Leda, Orus, Puck, Pulcherrima, Rasalgethi, Sadachbia, Sadaltager, Schedar, Sulafat, Umbriel, Vindemiatrix, Zephyr, Zubenelgenubi
openai_tts (fallback 1)
mcp__mcp-tts__openai_tts
- text: string (required)
- voice: string (default: "alloy") - alloy, ash, ballad, coral, echo, fable, nova, onyx, sage, shimmer, verse
- model: string (default: "gpt-4o-mini-tts")
- speed: number (0.25-4.0, default: 1.0)
- instructions: string (voice modulation hints)
elevenlabs_tts (fallback 2)
mcp__mcp-tts__elevenlabs_tts
- text: string (required)
say_tts (fallback 3 - local/free)
mcp__mcp-tts__say_tts
- text: string (required)
- voice: string (OPTIONAL - prefer leaving unset to use system default voice which sounds more natural)
- rate: integer (RECOMMENDED: 200-250 for natural speech, max 300 unless user asks faster; default: 200)
IMPORTANT for say_tts:
- Do NOT set a voice unless the user explicitly requests one - the system default sounds most natural
- Keep rate between 200-250 for comfortable listening; only go up to 275-300 if user wants faster speech
Auto-Assignment
When creating config for a new project:
- Read
references/voice-pools.jsonfor available voices - Check
~/.claude/tts-unavailable.jsonfor globally unavailable providers (shared across projects) - Scan
~/.claude/tts-assignments.jsonfor voices already assigned to other projects - Select 3 unused voices (one per message type) from first available provider
- If all voices used, cycle back with provider variation
- Save assignment to both project config and global assignments file
When a provider is marked unavailable in any project, also update ~/.claude/tts-unavailable.json:
{
"unavailable": ["google", "elevenlabs"],
"updated_at": "2025-01-15T10:30:00Z"
}
This prevents new projects from attempting providers known to be unconfigured.
Examples
Planning (after TodoWrite with multiple items):
"Here's the plan for the authentication feature. First, I'll create the login component. Then add session management. Finally, write the tests. Three tasks total."
Issue (after fixing an error):
"Found and fixed an issue. The rate limiter wasn't catching timeout errors. Added a try-catch block in the handler. Tests are passing now."
Summary (after completing a feature):
"All done with the authentication system. Added login, logout, and session management. Created five new files and updated the main router. Ready for review."
