nadia AI Voice Generator

Vocalize is a AI voice generator for making AI cover songs and text-to-speech. Choose from thousands of community-uploaded AI voices, or clone your own voice to sing any song and read any text aloud. Every voice model is user-generated, and any member can upload their own.

This page lets you create AI covers and text-to-speech in the nadia voice. Upload a song to hear it re-sung in this voice, or type any text to have it spoken aloud.

Open the Voice-to-Voice tab in the Voice Input section, upload a song file or paste a YouTube link, and click Convert. Vocalize separates the vocals, converts them to the nadia voice, and remixes them over the original instrumental; click the download arrow when it's done. For better results, use the advanced settings to adjust Pitch (to match the song's key) and Reverb (to blend the voice into the track).

Switch to the Text-to-Speech tab, and type what you want it to say. Choose a voice gender if available, set the speaking speed, and click Convert, then save with the download arrow. You can type in any language — our TTS supports them all — and slow the speed for clarity or speed it up for a snappier read.

Text-to-speech is usually ready in a few seconds. Voice-to-voice (cover) conversions take roughly 10–60 seconds depending on song length.
