Tools
1. Speech (speech.py)
Text-to-speech using ElevenLabs voices.
# Basic usage
python3 {baseDir}/scripts/speech.py "Hello world" -v <voice_id> -o output.mp3
# With format option
python3 {baseDir}/scripts/speech.py "Hello world" -v <voice_id> -o output.pcm --format pcm_44100
# With voice settings
python3 {baseDir}/scripts/speech.py "Hello" -v <voice_id> -o out.mp3 --stability 0.7 --similarity 0.8
2. Sound Effects (sfx.py)
Generate sound effects and short audio clips.
# Generate a sound
python3 {baseDir}/scripts/sfx.py "Cinematic boom" -o boom.mp3
# Generate a loop
python3 {baseDir}/scripts/sfx.py "Lo-fi hip hop beat" --duration 10 --loop -o beat.mp3
# Different format
python3 {baseDir}/scripts/sfx.py "Whoosh" -o whoosh.pcm --format pcm_44100
3. Music Generation (music.py)
Generate full musical compositions or instrumental tracks.
# Generate instrumental intro
python3 {baseDir}/scripts/music.py --prompt "Upbeat 6s news intro sting, instrumental" --length-ms 6000 -o intro.mp3
# Generate background bed
python3 {baseDir}/scripts/music.py --prompt "Soft ambient synth pad" --length-ms 30000 -o bed.mp3
# High quality MP3
python3 {baseDir}/scripts/music.py --prompt "Jazz piano" --length-ms 10000 -o jazz.mp3 --output-format mp3_44100_192
4. Voices (voices.py)
List available voices and their IDs.
# List voices
python3 {baseDir}/scripts/voices.py
# JSON output
python3 {baseDir}/scripts/voices.py --json
5. Voice Cloning (voiceclone.py)
Create instant voice clones from audio samples.
Security: by default this script will only read files from:
~/.openclaw/elevenlabs/voiceclone-samples/
Copy your samples there (or pass --sample-dir). Reading files outside the sample directory is blocked.
# Clone from audio files (put samples into ~/.openclaw/elevenlabs/voiceclone-samples)
python3 {baseDir}/scripts/voiceclone.py --name "MyVoice" --files sample1.mp3 sample2.mp3
# Use a custom sample dir
python3 {baseDir}/scripts/voiceclone.py --name "Andi" --sample-dir ./samples --files a.m4a b.m4a --language de --gender male
# With description and noise removal
python3 {baseDir}/scripts/voiceclone.py --name "Andi" --files a.m4a b.m4a --description "German male" --denoise
6. Quota & Usage (quota.py)
Check subscription quota and usage statistics.
# Show current quota
python3 {baseDir}/scripts/quota.py
# Include usage breakdown by voice
python3 {baseDir}/scripts/quota.py --usage
# Last 7 days usage
python3 {baseDir}/scripts/quota.py --usage --days 7
# JSON output
python3 {baseDir}/scripts/quota.py --json
