Architecture
Fetch News → Text Brief → Dual-Voice Script → TTS Audio → S3 Upload → RSS Update → DeliverConfiguration
Set these in your environment:
| Variable | Description |

Summary paragraphStep 3: Generate Dual-Voice Script
Rewrite the brief as a dialogue. Prefix each line with speaker tag:
HostA: Welcome to today's episode...
HostB: Some big stories today...
HostA: Right, let's start with...Guidelines:
- Host A: Explains and analyzes, knowledgeable but casual
- Host B: Asks, transitions, reacts
- Substantial turns, not one-liners
- Include analysis and discussion, not just headlines
- End with a lighter topic + sign-off
Step 4: Generate Audio
Fish Audio (recommended — natural, multi-voice):
python3 scripts/fish_dual_tts.py <script.txt> <output.mp3>Parses speaker tags, sends each segment to Fish Audio, concatenates into final MP3.
Edge TTS (free fallback, single voice):
edge-tts --voice en-US-GuyNeural --rate "+5%" --file script.txt --write-media output.mp3Step 5: Publish
bash scripts/generate_episode.sh <date> <EP-number> <title> <description> <mp3-file>What it does:
- Upload MP3 to S3
- Get actual duration via ffprobe
- Insert
<item>into RSS feed (newest first) - Update
<lastBuildDate>
Step 6: Deliver
Send text brief + audio via your preferred channel (Telegram, Discord, Slack, etc.)
RSS Feed
See references/rss-format.md for XML template.
Key rules:
<itunes:duration>= actual duration from ffprobe (never hardcode)<enclosure length>= actual file size in bytes<itunes:owner>with email for Apple/Spotify verification- Cover: 3000x3000 JPEG minimum
