description: Use this skill when the user requests to generate, create, or produce podcasts from text content. Converts written content into a two-host conversational podcast audio format with natural dialogue.

Podcast Generation Skill

Overview

This skill generates high-quality podcast audio from text content. The workflow includes creating a structured JSON script (conversational dialogue) and executing audio generation through text-to-speech synthesis.

Core Capabilities

• Convert any text content (articles, reports, documentation) into podcast scripts
• Generate natural two-host conversational dialogue (male and female hosts)
• Synthesize speech audio using text-to-speech
• Mix audio chunks into a final podcast MP3 file
• Support both English and Chinese content

Workflow

Step 1: Understand Requirements

When a user requests podcast generation, identify:

• Source content: The text/article/report to convert into a podcast
• Language: English or Chinese (based on content)
• Output location: Where to save the generated podcast
• You don't need to check the folder under `/mnt/user-data`

Step 2: Create Structured Script JSON

Generate a structured JSON script file in `/mnt/user-data/workspace/` with naming pattern: `{descriptive-name}-script.json`

The JSON structure:

{
  "locale": "en",
  "lines": [
    {"speaker": "male", "paragraph": "dialogue text"},
    {"speaker": "female", "paragraph": "dialogue text"}
  ]
}

Step 3: Execute Generation

Call the Python script:

python /mnt/skills/public/podcast-generation/scripts/generate.py \
  --script-file /mnt/user-data/workspace/script-file.json \
  --output-file /mnt/user-data/outputs/generated-podcast.mp3 \
  --transcript-file /mnt/user-data/outputs/generated-podcast-transcript.md

Parameters:

• `--script-file`: Absolute path to JSON script file (required)
• `--output-file`: Absolute path to output MP3 file (required)
• `--transcript-file`: Absolute path to output transcript markdown file (optional, but recommended)

> [!IMPORTANT] > - Execute the script in one complete call. Do NOT split the workflow into separate steps. > - The script handles all TTS API calls and audio generation internally. > - Do NOT read the Python file, just call it with the parameters. > - Always include `--transcript-file` to generate a readable transcript for the user.

Script JSON Format

The script JSON file must follow this structure:

{
  "title": "The History of Artificial Intelligence",
  "locale": "en",
  "lines": [
    {"speaker": "male", "paragraph": "Hello Deer! Welcome back to another episode."},
    {"speaker": "female", "paragraph": "Hey everyone! Today we have an exciting topic to discuss."},
    {"speaker": "male", "paragraph": "That's right! We're going to talk about..."}
  ]
}

Fields:

• `title`: Title of the podcast episode (optional, used as heading in transcript)
• `locale`: Language code - "en" for English or "zh" for Chinese
• `lines`: Array of dialogue lines
• `speaker`: Either "male" or "female"
• `paragraph`: The dialogue text for this speaker

Script Writing Guidelines

When creating the script JSON, follow these guidelines:

Format Requirements

• Only two hosts: male and female, alternating naturally
• Target runtime: approximately 10 minutes of dialogue (around 40-60 lines)
• Start with the male host saying a greeting that includes "Hello Deer"

Tone & Style

• Natural, conversational dialogue - like two friends chatting
• Use casual expressions and conversational transitions
• Avoid overly formal language or academic tone
• Include reactions, follow-up questions, and natural interjections

Content Guidelines

• Frequent back-and-forth between hosts
• Keep sentences short and easy to follow when spoken
• Plain text only - no markdown formatting in the output
• Translate technical concepts into accessible language
• No mathematical formulas, code, or complex notation
• Make content engaging and accessible for audio-only listeners
• Exclude meta information like dates, author names, or document structure

Podcast Generation Example

User request: "Generate a podcast about the history of artificial intelligence"

Step 1: Create script file `/mnt/user-data/workspace/ai-history-script.json`:

{
  "title": "The History of Artificial Intelligence",
  "locale": "en",
  "lines": [
    {"speaker": "male", "paragraph": "Hello Deer! Welcome back to another fascinating episode. Today we're diving into something that's literally shaping our future - the history of artificial intelligence."},
    {"speaker": "female", "paragraph": "Oh, I love this topic! You know, AI feels so modern, but it actually has roots going back over seventy years."},
    {"speaker": "male", "paragraph": "Exactly! It all started back in the 1950s. The term artificial intelligence was actually coined by John McCarthy in 1956 at a famous conference at Dartmouth."},
    {"speaker": "female", "paragraph": "Wait, so they were already thinking about machines that could think back then? That's incredible!"},
    {"speaker": "male", "paragraph": "Right? The early pioneers were so optimistic. They thought we'd have human-level AI within a generation."},
    {"speaker": "female", "paragraph": "But things didn't quite work out that way, did they?"},
    {"speaker": "male", "paragraph": "No, not at all. The 1970s brought what's called the first AI winter..."}
  ]
}

Step 2: Execute generation:

python /mnt/skills/public/podcast-generation/scripts/generate.py \
  --script-file /mnt/user-data/workspace/ai-history-script.json \
  --output-file /mnt/user-data/outputs/ai-history-podcast.mp3 \
  --transcript-file /mnt/user-data/outputs/ai-history-transcript.md

This will generate:

• `ai-history-podcast.mp3`: The audio podcast file
• `ai-history-transcript.md`: A readable markdown transcript of the podcast
