Kalvia AI · AI voice generator
AI voiceovers for videos, adverts and films
A script in, a voiceover out.
Kalvia's audio generator turns text into speech for narration, adverts and character lines. Choose a model and a voice, paste up to 9,999 characters, and get an audio file you can drop onto the editor's timeline.
Speech is priced by the number of characters, and the price is shown before you generate.
