How to Clone Your Voice with AI Using Bitcoin Lightning
Upload a voice sample, pay once, get a permanent Voice ID. Generate speech in your own voice anytime after.
For Humans
Use the web UI — no setup required.
Voice cloning services charge $5–22/month for limited slots and require an account with sensitive data. On Sats4AI it's 7,500 sats (~$3) once — your Voice ID is permanent and works with text-to-speech at 300 sats per generation forever. No account, no subscription, no data stored about you.
Consistent brand voice
Clone your voice once and use it for every podcast intro, explainer video, or narration you ever produce. Consistent tone and delivery without recording each time.
Voiceovers without recording sessions
Need narration at midnight? Just type the script and generate in your voice. No microphone setup, no takes, no editing — just pay 300 sats and download.
Multilingual content in your voice
Type text in any of the 40+ supported languages and the cloned voice speaks it. Produce localized content without hiring voice actors per language.
Edit and re-voice recordings
Transcribe an existing recording, correct mistakes in the text, then regenerate it in your cloned voice — cleaner output without re-recording.
How It Works
Minimax Voice Cloning
Upload once → receive a permanent Voice ID → use it on the Text-to-Speech page at 300 sats per generation, forever. Accuracy slider (0–1), noise reduction, and volume normalization included.
Upload your voice sample
Upload an MP3, M4A, or WAV file (10s–5 min). Clear audio with minimal background noise works best.
Adjust settings
Set the accuracy level (default 0.7). Optionally enable noise reduction or volume normalization.
Pay the Lightning invoice
Click Clone Voice. A QR code appears for 7,500 sats. Scan with any Lightning wallet.
Get your Voice ID
Your voice is cloned and you receive a permanent Voice ID. Save it — you'll use it for every speech generation.
Generate speech in your voice
Paste your Voice ID into the Text to Speech tool, enter any text, and generate at 300 sats per generation.
For Agents
Integrate via L402, MCP, or OpenClaw — no account, no API key.
The voice cloning endpoint supports L402 authentication: an agent uploads a voice sample, pays a one-time 7,500-sat Lightning invoice, and receives a Voice ID to store and reuse. Subsequent text-to-speech calls with that Voice ID cost 300 sats each via the same L402 flow.
Per-user voice libraries
An app clones each user's voice on onboarding, stores the Voice ID, then generates personalized audio notifications or content in their own voice.
Automated voiceover pipelines
An agent generates article text with AI chat, then calls TTS with a stored Voice ID to produce branded audio — same voice, every time, fully automated.
Multilingual voice delivery
Clone the voice once, then generate speech in 40+ languages — same Voice ID, same voice, different languages. No per-language recording needed.
Voice calls in your voice
Generate a message in a cloned voice with TTS, then deliver it as an automated phone call — personalized voice broadcasting at scale.
