Character styles

These presets combine pitch and tone for a character-like effect. The result depends on your recording; they do not create a realistic voice of a different age or gender.

Using this tool

Choose your voice file, select an effect, and preview a short section. Generate the full result, compare A/B, then download a new WAV or MP3. Your original file is never overwritten.

What to check

Pitch changes preserve the recording length and speaking speed. These are audio effects, not AI voice cloning, gender conversion or guaranteed anonymization. Effects also change background sounds. Large pitch shifts may sound synthetic. Echo is kept inside the original duration.
