Key FeaturesFeatures of AI Voice Generator
300+ AI voices in 175+ languages
Browse 300+ natural-sounding AI voices across a wide variety of accents and 175+ languages. Optimize for a regional accent, switch genders, or layer in cultural flavor without booking voice actors. Every text-to-speech voice created here ships studio-grade voice quality, ready for narration, promo videos, and podcasts.
Tone, pace, and intonation control
Direct the performance line by line. Adjust pacing, stress key phrases, soften punctuation pauses, or push the energy up for a punchy social clip. Your script reads with the intonation and emotion you'd use, not a robotic, computer-generated TTS algorithm.
Voice cloning from a short 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 keep the same delivery across thousands of high-quality generations.
Multilingual AI dubbing with lip sync
Dub any voiceover into 175+ languages with AI dubbing that keeps tone, timing, and natural cadence intact. Pair voice with AI video translator and your presenter lip-syncs the new language on screen.
Built-in video editing tools and captions
Drop the voice you created straight into the AI video editor alongside visuals, music, and auto-captions. Skip the export-import dance across three different tools to make your video. You get one workspace to streamline content creation from script to share-ready file.
Use cases

Replace a paid voice actor for your intro, mid-roll ad, or sponsor spot. Type the spot, 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. Personalize and localize reads in 175+ languages and pair them with a product demo video so launches go live the same week your script lands.
Global teams need consistent training in every language. Write a single script, automate AI voice generation across 175+ languages, and deliver a multilingual training video library without ever stepping into a recording booth.
