Questions, answered
Everything about our voice changer
How does the AI voice changer work?
Lyssna's voice changer analyzes the vocal characteristics of your uploaded recording — pitch, timbre, cadence, and resonance — then applies AI voice conversion to match a target style. The result is a natural-sounding transformed voice, not just a pitch-shifted filter.
Is the voice changer free to use?
Yes. Every new account includes free starter credits you can use for voice transformations. No credit card required — sign in with Google and transform your first recording.
What voice transformation styles are available?
Lyssna supports gender swaps, age shifts, accent and character styles, robotic and synthetic effects, deep authoritative tones, and pitch adjustments. The full list of available styles is shown in the playground when you upload your recording.
What audio formats can I upload?
You can upload MP3, WAV, M4A, OGG, and most common audio formats. Video files like MP4 and MOV are also supported — we extract the audio track automatically before processing.
Will the transformed voice sound natural?
For most transformation styles, yes. Our AI preserves the natural prosody and emotional character of the original speech while applying the target voice style. Extreme transformations (like deep robotic effects) trade naturalness for creativity by design.
Can I use the transformed audio commercially?
Yes, on paid plans. Transformed audio generated with paid credits can be used in YouTube videos, podcasts, games, and commercial projects. Free-tier output is for personal and evaluation use only.
How long can my audio recording be?
The playground accepts files up to 25 MB (roughly 25 minutes at standard quality). Paid plans raise this limit for longer voice acting sessions and full episode transformations.
Is my uploaded audio private?
Yes. Uploaded files are processed securely and are not shared or used for model training without your consent. Signed-in accounts get encrypted storage with a clear-at-any-time option — you own every file.
