ComfyUI TTS Skill

Generate speech audio using ComfyUI's Qwen-TTS service. This skill allows you to convert text to speech through ComfyUI's API.

Configuration

Environment Variables

Set these environment variables to configure the ComfyUI connection:

export COMFYUI_HOST="localhost"      # ComfyUI server host
export COMFYUI_PORT="8188"           # ComfyUI server port
export COMFYUI_OUTPUT_DIR=""         # Optional: Custom output directory

Usage

Basic Text-to-Speech

Generate audio from text using default settings:

scripts/tts.sh "你好，世界"

Advanced Options

Customize voice characteristics:

# Specify character and style
scripts/tts.sh "你好" --character "Girl" --style "Emotional"

# Change model size
scripts/tts.sh "你好" --model "3B"

# Specify output file
scripts/tts.sh "你好" --output "/path/to/output.wav"

# Combine options
scripts/tts.sh "你好，这是测试" \
  --character "Girl" \
  --style "Emotional" \
  --model "1.7B" \
  --output "~/audio/test.wav"

Available Options

Option	Description	Default
--character	Voice character (Girl/Boy/etc.)	"Girl"
--style	Speaking style (Emotional/Neutral/etc.)	"Emotional"
--model	Model size (0.5B/1.7B/3B)	"1.7B"
--output	Output file path	Auto-generated
--temperature	Generation temperature (0-1)	0.9
--top-p	Top-p sampling	0.9
--top-k	Top-k sampling	50

Workflow

The skill performs these steps:

1. Construct Workflow: Builds a ComfyUI workflow JSON with your text and settings
2. Submit Job: Sends the workflow to ComfyUI's /prompt endpoint
3. Poll Status: Monitors job completion via /history endpoint
4. Retrieve Audio: Returns the path to the generated audio file

Troubleshooting

Connection Refused

• Verify ComfyUI is running: curl http://$COMFYUI_HOST:$COMFYUI_PORT/system_stats
• Check host and port settings

Job Timeout

• Large models (3B) take longer to generate
• Try smaller models (0.5B, 1.7B) for faster results

Output Not Found

• Check ComfyUI's output directory configuration
• Verify file permissions

API Reference

The skill uses ComfyUI's native API endpoints:

• POST /prompt - Submit workflow
• GET /history - Check job status
• Output files are saved to ComfyUI's configured output directory
