Background
SignalDesk published strong written analysis but audio audience was untapped. Recording two hosts in studio took half a day per episode — only 2 episodes/month shipped.
Pipeline
From Build an AI Podcast Generator:
Article URL or markdown
→ Extract + outline key claims
→ Sonnet: two-host dialogue script (6-8 min)
→ ElevenLabs: voice A + voice B per line
→ ffmpeg: stitch + normalize
→ Human listen + factual check
→ Upload + show notes
Month one quality gate
17% of episodes rejected — usually wrong stat or over-strong claim not in source article. Prompt added: only assert facts present in source.
Rejection rate fell to 6% by month three.
Results
| Metric | Manual recording | Pipeline |
|---|---|---|
| Episodes / month | 2 | 12 |
| Production time each | 4 hr | 35 min |
| Monthly cost | ~$800 talent | ~$50 API |
| Audio downloads (90d) | baseline | +41% |
Takeaway
AI podcast generation is repurposing infrastructure, not replacing flagship shows. Human listen before publish is non-negotiable for factual content. Start with workflow guide.
Lessons learned
- 01
Two distinct voice IDs mattered — listeners abandoned when hosts sounded identical.
- 02
Source article fed verbatim into prompt caused monotone dialogue — outline step fixed it.
- 03
Show notes and timestamps auto-generated saved another 20 min per episode.
- 04
Factual drift happened on stats-heavy posts — human listen gate stayed permanent.
- 05
6-8 minute target beat 15-minute ramble — edit discipline in dialogue prompt.
