Implements comprehensive Text-to-Speech integration for BMAD agents using a generic
TTS_INJECTION marker system. When AgentVibes (or any compatible TTS provider) is
installed, all BMAD agents can speak their responses with unique AI voices.
## Key Features
**Provider-Agnostic Architecture**
- Uses generic `TTS_INJECTION` markers instead of vendor-specific naming
- Future-proof for multiple TTS providers beyond AgentVibes
- Clean separation - BMAD stays TTS-agnostic, providers handle injection
**Installation Flow**
- BMAD → AgentVibes: TTS instructions injected when AgentVibes detects existing BMAD installation
- AgentVibes → BMAD: TTS instructions injected during BMAD installation when AgentVibes detected
- User must manually create voice assignment file when AgentVibes installs first (documented limitation)
**Party Mode Voice Support**
- Each agent speaks with unique assigned voice in multi-agent discussions
- PM, Architect, Developer, Analyst, UX Designer, etc. - all with distinct voices
**Zero Breaking Changes**
- Fully backward compatible - works without any TTS provider
- `TTS_INJECTION` markers are benign HTML comments if not processed
- No changes to existing agent behavior or non-TTS workflows
## Implementation Details
**Files Modified:**
- `tools/cli/installers/lib/core/installer.js` - TTS injection processing logic
- `tools/cli/lib/ui.js` - AgentVibes detection and installation prompts
- `tools/cli/commands/install.js` - Post-install guidance for AgentVibes setup
- `src/utility/models/fragments/activation-rules.xml` - TTS_INJECTION marker for agents
- `src/core/workflows/party-mode/instructions.md` - TTS_INJECTION marker for party mode
**Injection Point System:**
```xml
<rules>
- ALWAYS communicate in {communication_language}
<!-- TTS_INJECTION:agent-tts -->
- Stay in character until exit selected
</rules>
```
When AgentVibes is detected, the installer replaces this marker with:
```
- When responding to user messages, speak your responses using TTS:
Call: `.claude/hooks/bmad-speak.sh '{agent-id}' '{response-text}'` after each response
IMPORTANT: Use single quotes - do NOT escape special characters like ! or $
```
**Special Character Handling:**
- Explicit guidance to use single quotes without escaping
- Prevents "backslash exclamation" artifacts in speech
**User Experience:**
```
User: "How should we architect this feature?"
Architect: [Text response] + 🔊 [Professional voice explains architecture]
```
Party Mode:
```
PM (John): "I'll focus on user value..." 🔊 [Male professional voice]
UX Designer (Sara): "From a user perspective..." 🔊 [Female voice]
Architect (Marcus): "The technical approach..." 🔊 [Male technical voice]
```
## Testing
**Unit Tests:** ✅ 62/62 passing
- 49/49 schema validation tests
- 13/13 installation component tests
**Integration Testing:**
- ✅ BMAD → AgentVibes (automatic injection)
- ✅ AgentVibes → BMAD (automatic injection)
- ✅ No TTS provider (markers remain as comments)
## Documentation
Comprehensive testing guide created with:
- Both installation scenario walkthroughs
- Verification commands and expected outputs
- Troubleshooting guidance
## Known Limitations
**AgentVibes → BMAD Installation Order:**
When AgentVibes installs first, voice assignment file must be created manually:
```bash
mkdir -p .bmad/_cfg
cat > .bmad/_cfg/agent-voice-map.csv << 'EOF'
agent_id,voice_name
pm,en_US-ryan-high
architect,en_US-danny-low
dev,en_US-joe-medium
EOF
```
This limitation exists to prevent false legacy v4 detection warnings from BMAD installer.
**Recommended:** Install BMAD first, then AgentVibes for automatic voice assignment.

## Breaking Changes
None. Feature is opt-in and requires separate TTS provider installation.
