Key FeaturesKey features of the AI Voice Generator
300+ AI voices in over 175 languages
Browse 300+ natural-sounding AI voices across a wide range of accents and 175+ languages. Optimise for a regional accent, switch genders, or add cultural nuance without booking voice actors. Every text-to-speech voice created here delivers studio-grade voice quality, ready for narration, promo videos, and podcasts.
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. Your script is delivered with the intonation and emotion you would use yourself, 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 175+ languages with AI dubbing that keeps tone, timing, and natural cadence intact. Pair the voice with the 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 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 share-ready file.
Use cases
Faceless creators burn hours recording, retaking, and editing audio. Paste your script, generate AI voices that match the vibe, and ship a vertical or 16:9 clip the same day, ready for any social feed.
Online courses live or die on engaging narration. Create voiceovers for every lesson in multiple languages, refresh training materials without re-recording, and add subtitles automatically with the subtitle generator for accessibility.
Hiring narrators is slow and expensive, and DIY audio rarely lands. Pick an expressive voice, generate chapter by chapter, and produce a finished audiobook with consistent tone and human-like speech across hundreds of pages.
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.
