# Daily Digest Podcast Generator
|
|
|
|
Converts daily digest blog posts into audio podcast format using OpenAI TTS.
|
|
|
|
## Overview
|
|
|
|
This system automatically:
|
|
1. Fetches the latest daily digest from blog-backup
|
|
2. Converts the content to speech using OpenAI TTS
|
|
3. Generates an RSS feed for podcast distribution
|
|
4. Stores audio files for serving
|
|
|
|
## Setup
|
|
|
|
### 1. OpenAI API Key
|
|
|
|
You need an OpenAI API key with TTS access:
|
|
|
|
```bash
|
|
# Create the environment file
|
|
echo "OPENAI_API_KEY=sk-your-key-here" > ~/.openclaw/workspace/.env.openai
|
|
```
|
|
|
|
Get your API key from: https://platform.openai.com/api-keys
|
|
|
|
### 2. Test the Generator
|
|
|
|
```bash
|
|
cd ~/.openclaw/workspace/scripts/podcast-generator
|
|
./generate-podcast.sh
|
|
```
|
|
|
|
### 3. Manual Generation
|
|
|
|
To generate a podcast for a specific digest:
|
|
|
|
```bash
|
|
# The script auto-detects the latest digest
|
|
./generate-podcast.sh
|
|
```
|
|
|
|
### 4. RSS Feed
|
|
|
|
The RSS feed is generated at:
|
|
- Local: `~/.openclaw/workspace/podcast/rss.xml`
|
|
- Web: Should be hosted on Mission Control or deployed to static hosting
|
|
|
|
## Cost Estimate
|
|
|
|
- Daily digest: ~2,000 characters
|
|
- OpenAI TTS: $0.015 per 1,000 characters
|
|
- **Cost per episode: ~$0.03**
|
|
- Monthly cost (30 episodes): ~$0.90

Create the `.env.openai` file with your API key.
|
|
|
|
### "No digest found"
|
|
The blog-backup may not have a digest for today yet. Check https://blog-backup-two.vercel.app
|
|
|
|
### Audio file is empty
|
|
Check OpenAI API rate limits and billing status.
