Key featuresKey features of the AI Voice Generator
AI voices in 177+ languages and dialects
Browse 300+ natural-sounding AI voices across a wide variety of accents and 177+ languages and dialects. Optimise for a regional accent, switch genders, or layer in cultural flavour without booking voice actors. Every text-to-speech voice created here offers studio-grade voice quality, ready for narration, promo videos, podcasts, and an AI podcast generator.
Tone, pace, and intonation control
Direct the performance line by line. Adjust the pacing, emphasise key phrases, soften pauses at punctuation, or increase the energy for a punchy social clip or AI video ads. Your script will be delivered with the intonation and emotion you would naturally use, not like a robotic, computer-generated TTS algorithm.
Voice cloning from a short audio sample
Clone your own voice in about a minute and use it as your signature narrator across every video, course, or podcast. Train it once with AI voice cloning, then maintain the same delivery across thousands of high-quality generations.
Multilingual AI dubbing with lip sync
Dub any voiceover into 177+ languages and dialects with AI dubbing that preserves tone, timing, and natural cadence. Pair the voice with the AI video translator and your presenter will lip-sync the new language on screen.
Built-in video editing tools and subtitles
Drop the voice you created straight into the AI video editor along with visuals, music, and auto-captions. Skip the back-and-forth of exporting and importing across three different tools to make your video. You get a single workspace that streamlines content creation from script to a file that is ready to share.
Use cases
Faceless creators spend hours recording, redoing, and editing audio. Paste your script, generate AI voices that match the mood, and publish a vertical or 16:9 clip the same day, ready for any social feed.
Online courses depend heavily on engaging narration. Create voiceovers for every lesson in multiple languages, update training materials without re-recording, and add subtitles automatically with the subtitle generator for better accessibility.
Hiring narrators is slow and expensive, and DIY audio rarely works well. Choose an expressive voice, generate your book chapter by chapter, and produce a finished audiobook with a consistent tone and natural, human-like speech across hundreds of pages.
Replace a paid voice actor for your intro, mid-roll ad, or sponsor spot. Type out the script, choose a voice that matches your show’s energy, and drop a polished read into your edit in under five minutes.
Marketing teams need professional voiceovers for every campaign, region, and asset. Personalise and localise in 177+ languages and dialects, and pair the voice track with a product demo video, so launches can go live in the same week your script is finalised.
Global teams need consistent training in every language. Write a single script, automate AI voice generation across 177+ languages and dialects, and deliver a multilingual training video library without ever having to step into a recording booth.
