Understanding Voice Settings
βοΈ Stability
Higher values = more consistent voice, but more monotone. Lower values = more expressive, but more variable.
ποΈ Clarity + Similarity
Clear voice vs. similar tone to original. Find balance depending on application.
π¨ Style
Increases expression but can cause instability. Use with caution.
π Speaker Boost
Improves similarity to original speaker. Recommended for voice cloning.
Pronunciation Optimization
ElevenLabs understands phonetic markings. For difficult words or names, you can control the pronunciation:
SSML Support
ElevenLabs supports SSML (Speech Synthesis Markup Language) for advanced control:
- <break time="500ms"/> βΈοΈ Insert pauses
- <emphasis>important</emphasis> π¬ Emphasis
- <prosody rate="slow">slowly</prosody> π’ Speech rate
Controlling Emotions and Tone
Use special tags to control emotions directly in the text:
π [excited] I can hardly wait!
π [sad] I'm really sorry about that.
π [shouting] Watch out!
π [softly] Come here...
β Use punctuation for natural pauses
β Test different Stability settings
β Save successful settings as preset
Ethics & Responsibility
When is Voice Cloning Ethical?
Voice cloning is a powerful tool β with great power comes great responsibility. Here are the principles for ethical use:
- Your own voice: You may clone and use your own voice
- Consent: Others must consent to the use of their voice
- Transparency: Listeners should know they are hearing an AI voice
- Context: Satire and parody have different rules than commercial use
Consent and Rights
Before cloning someone else's voice:
- Obtain written consent from the person
- Create a usage rights agreement (where, how long, what purposes)
- For commercial use: Seek legal advice
- Give special protection to voices of minors
Watermarks and Verification
ElevenLabs adds an indelible watermark to all generated audio. This enables identification of AI-generated content β even after format changes or editing.
