Voiceover

Voiceover

Generates voiceover audio from a text file using Chatterbox TTS with voice cloning.

When to use this skill

USE THIS SKILL when the user wants to:

• Generate a voiceover/narration from ANY text file
• Create audio content with voice cloning
• Says "voiceover", "generate audio", "create narration"
• Has already created a script (via create-script skill) and wants audio

IMPORTANT: If the user provides raw content AND says "voiceover", use the create-script skill FIRST to create the text file, THEN use this skill.

CLI Usage

The script accepts command-line arguments:

uv run scripts/voiceover_script.py -i <input.txt> -o <output.wav> [-v <voice.wav>]

Instructions

Step 1: Identify the input file

Determine which text file to convert:

• Check what file was just created by create-script skill
• Or use the file the user specifies
• Verify the file exists before proceeding

Step 2: Determine output filename

• Match the input filename's slug exactly (e.g., if input is entry-009.txt, output should be entry-009.wav)
• If a custom output name is requested, use it

Step 3: Launch in background

Use nohup with uv run and CLI arguments to run detached:

nohup uv run scripts/voiceover_script.py -i <input_file> -o <output_file> > voiceover.log 2>&1 &

Note: If you omit -o, the output will auto-generate as <input_name>.wav

Step 4: Verify it started

Wait briefly and check the log:

sleep 2 && cat voiceover.log

Expected output:

Using device: cuda
Loading model...
Fetching 10 files: 100%|██████████| 10/10 [00:00<?, ?it/s]

Step 5: Inform the user

Tell the user:

1. The voiceover generation has been launched in the background
2. Input file: [the file being converted]
3. Output file: [the wav file that will be created]
4. Estimated time: ~1-2 minutes per 100 words (GPU), longer on CPU
5. Monitor progress with: tail -f voiceover.log

Examples

Example 1: Custom input file

nohup uv run scripts/voiceover_script.py -i opencode_skills_video.txt > voiceover.log 2>&1 &

Output: opencode_skills_video.wav (auto-generated)

Example 2: Custom input and output

nohup uv run scripts/voiceover_script.py -i my_script.txt -o final_audio.wav > voiceover.log 2>&1 &

Example 3: Different voice reference

nohup uv run scripts/voiceover_script.py -i script.txt -v different_voice.wav > voiceover.log 2>&1 &

Output

The script produces a WAV file with:

• 24kHz sample rate
• Normalized to -19 LUFS
• 0.5 second gaps between chunks

File Requirements

Before running, ensure these files exist in the project directory:

• Your input text file
• Voice reference file (default: clone.wav)
