# Blog Audio: Gemini TTS Narration for Blog Posts

Generate professional audio narration of blog content using Google's Gemini TTS.
Three modes: summary (200-300 word spoken overview), full article read-aloud,
or two-speaker podcast dialogue. 30 voices, 80+ languages, HTML5 embed output.

## Quick Reference

| Command | What it does |
|---------|-------------|
| `/blog audio generate <file>` | Generate audio narration of a blog post |
| `/blog audio voices` | Show available voices with characteristics |
| `/blog audio setup` | Check/configure API key for Gemini TTS |

## Prerequisites

- Python 3.11+ (venv managed automatically by `run.py`)
- `GOOGLE_AI_API_KEY` environment variable (same key used by blog-image)
- FFmpeg (for WAV-to-MP3 conversion; falls back to WAV if missing)

## Always Use run.py Wrapper

```bash
# CORRECT:
python3 scripts/run.py generate_audio.py --text "..." --voice Charon --json

# WRONG:
python3 scripts/generate_audio.py --text "..."  # Fails without venv
```

## API Key Check (Gate Pattern)

Before generating audio, check for the API key:

```bash
test -n "${GOOGLE_AI_API_KEY:-}" && echo "GOOGLE_AI_API_KEY is set" || echo "GOOGLE_AI_API_KEY is not set"
```

- If set: proceed with generation
- If not set: guide the user:
  "Audio generation requires a Google AI API key. Get one free at https://aistudio.google.com/apikey
   Then set it: `export GOOGLE_AI_API_KEY=your-key`
   This can be the same key used by `/blog image`, but it must be exported in the shell."
- **When called internally** (from blog-write): return silently if key is missing.
  Never block the writing workflow.

## Setup

For `/blog audio setup`:

1. Check if `GOOGLE_AI_API_KEY` is set in environment
2. If blog-image uses project `.mcp.json`, confirm the referenced env var is exported
3. If not, guide user to https://aistudio.google.com/apikey
4. Verify with a dry run: `python3 scripts/run.py generate_audio.py --text "Test" --dry-run --json`
