The Short Answer
The best AI dubbing software depends on what you are dubbing. To translate a video you own and publish it — with voice cloning and lip-sync — use a post-production tool such as ElevenLabs, HeyGen, Rask AI or Synthesia. To hear a stream, game or call in your language while it plays on your PC, you need a live dubber such as VoxisLive.
In more detail: ElevenLabs when the voice itself is the product and you want an API to automate it; HeyGen when a face is on screen and the lips have to match; Rask AI for a YouTube channel or a back catalogue; Synthesia for company training and explainer video; Maestra if you dub files and also broadcast live through OBS or Zoom; Speechify Studio for voice-over-led content; and YouTube's built-in auto-dubbing if you already publish there. All of these work on content you produce. VoxisLive covers the other case — audio you are receiving — on Windows and Linux, in 79 target languages, with no file to upload and no finished file coming out. The table and the eight sections below show which is which.

Two Kinds of AI Dubbing
Most AI dubbing software is post-production. You upload a finished video — or paste a link to one you have the rights to — and the service transcribes it, translates the script, synthesizes speech (often in a clone of the original speaker), optionally re-renders the lips to match, and hands back a new video or audio track. You can review and correct it before anyone hears it. Processing takes time, which is fine, because nobody is waiting live.
Live dubbing runs the other way round. The audio is happening now — a stream, a game cut-scene, a video call — and the translation has to be spoken while it plays. There is nothing to upload and nothing to edit afterwards: a simultaneous-interpretation model listens, translates and speaks, staying a few seconds behind the original. Live dubbing trades polish for immediacy. There is no lip-sync and no editing pass, but you follow the thing as it happens.
Live dubbing splits once more: tools that dub your own broadcast for an audience (Maestra's live mode, Deepdub, CAMB.AI) and tools that dub what you are receiving, for your own ears (VoxisLive); our live AI dubbing page compares both groups. This guide starts with the post-production tools, because that is what most people searching for AI dubbing software need.
The Eight Tools, Compared
ElevenLabs Dubbing — voice-cloned dubs with an API
ElevenLabs dubs uploaded files or pasted URLs into more than 90 languages and accents, according to its dubbing page, and delivers each translation in an automatic clone of the original speaker's voice, keeping identity, pitch and tone without manual setup. Its timing logic is designed so the dub starts and stops where the original does. Dubbing is available on every plan, including the free one, which carries a small watermarked allowance (its dubbing page lists 0.4 minutes of Dubbing v2 and 5 minutes of watermarked v1 a month); paid plans from $6 a month add more minutes, and API access is available for teams that want to automate a localization pipeline. It is a strong pick when the voice is the product — a podcaster, narrator or creator who wants to sound like themselves in another language. Its dubbing page focuses on voice and timing; if you need mouth movements re-rendered, compare it with the lip-sync tools below.
HeyGen — lip-synced translation for on-camera video
HeyGen's video translator takes an uploaded video or a YouTube link and returns it in one of 175+ languages, with voice cloning to keep the speaker's voice and lip-sync that reshapes mouth movements to the new language. That combination matters for talking-head content — founders, course instructors, sales and marketing videos — where a mismatched mouth is the first thing a viewer notices. There is a limited free plan — three videos a month, up to one minute each, in 30+ languages according to its pricing page; the 175+ languages and voice cloning come with paid plans, from $29 a month on monthly billing ($24 a month billed annually). It is a publishing tool: you get a finished video to review and post, not a live feed.
Rask AI — localizing a YouTube channel or video library
Rask AI translates and dubs video into 135+ languages, with voice cloning in 32 languages and lip-sync from the Creator Pro plan ($150 a month on monthly billing), and accepts either uploads or YouTube links. Its plans are sized in minutes — 25 a month on the $60 Creator plan, or a yearly pool on annual billing — which suits a creator or team working through a back catalogue rather than a single clip. A 3-minute free trial lets you test your own footage first; paid plans start at $60 a month on monthly billing, less on annual billing. Like the other post-production tools here, it is built for content you own and will publish.
Synthesia — dubbing inside a corporate video platform
Synthesia is best known for AI-avatar video, and its dubbing feature brings existing footage into the same workspace: upload MP4, MOV or WebM files, or dub straight from a YouTube link, into 140+ languages according to its feature page (its pricing table lists 70+ output languages on the self-serve plans and 140+ on Enterprise), with the speaker's voice preserved and lip-sync. The free Basic plan includes 10 minutes of AI dubbing a month (downloading videos needs a paid plan), and Starter is $29 a month on monthly billing ($18 a month billed annually). It fits companies producing training, onboarding and explainer videos in many languages, where review workflows and brand consistency matter more than turnaround.
Maestra — file dubbing plus a live mode for broadcasters
Maestra covers both sides of the market. Its video dubber takes uploads, links and YouTube videos — as well as Reels, TikToks and Shorts — into 125+ languages, with 850+ AI voices according to its video-dubber page and voice cloning across 30+ languages, and exports MP4 or separate audio tracks. It also offers real-time voice dubbing for broadcasts through OBS, Zoom, Microsoft Teams and vMix, built for a presenter or streamer who wants their own audience to hear them in another language. A free trial needs no card. If you produce content and also go live, it puts both in one platform.
Speechify Studio — voice-over-first dubbing
Speechify's dubbing lives in Speechify Studio, its AI voice-over workspace. The dubbing page lists 60+ languages and voice cloning from a recording of about 20 seconds, and the workflow centres on uploading content or working from a script. Its pricing page puts the Dubbing Studio on the free plan, while voice cloning and commercial use need a paid plan, billed annually. It makes sense when a project is voice-over-led — narration, training, marketing explainers — and you already write or edit scripts. The dubbing page does not list lip-sync among its features, so for on-camera speakers compare it with HeyGen, Rask AI or Synthesia.
YouTube auto-dubbing — built into YouTube for eligible creators
If you publish on YouTube, the platform may already dub for you. Automatic dubbing adds translated audio tracks to eligible videos up to 120 minutes long and is switched on by default for eligible creators, according to its help page; there, English videos can be dubbed into 20 languages, while many other languages are dubbed into English. YouTube's February 2026 announcement says auto dubbing is now available to everyone, with 27 languages in total. YouTube does not advertise voice cloning; some languages get "expressive speech" that follows the original pitch and intonation, and lip-sync is an experiment limited to select channels. YouTube itself warns that automatic dubs may contain errors. It only applies to your own uploads, and no separate price is listed.
VoxisLive — live dubbing for whatever is playing on your PC
VoxisLive is on this list for a different job: it never touches files. It runs on Windows 10/11 and Linux, captures whatever your computer is playing — a stream, a game, a film, a video call — and speaks a translation into your headphones in one of 79 target languages, a few seconds behind the original, with live captions alongside. Meeting mode adds the other direction: your translated voice reaches Zoom, Teams or Meet through a virtual microphone. Meeting mode uses paid minutes and, on Windows, needs a virtual audio cable such as VB-CABLE — the app will not start a Meeting session without one (on Linux it creates its own virtual microphone). In Video/Game mode it can also keep the incoming speaker's own voice on some target languages. The free tier gives 15 minutes of the premium voice once, then 10 minutes a day in Video/Game mode, spoken in 35 of the 79 languages (the rest arrive as captions); beyond that, prepaid minute packs with no subscription. What it cannot do: take a video file or a YouTube link, render lip-sync, or produce a dubbed file to publish.
When a Post-Production Tool Is the Better Choice
For most dubbing jobs, a live dubber is the wrong tool, and it is worth being specific about when:
- You own the video and want to publish it in other languages. Upload it to ElevenLabs, HeyGen, Rask AI, Synthesia or Maestra and get a finished file back. VoxisLive has no file input and no file output.
- You need the lips to match. HeyGen, Rask AI, Synthesia and Maestra re-render mouth movements. VoxisLive never touches the picture.
- You want your own voice in another language on a published video. Cloning your voice from your recordings is the core feature of these tools. VoxisLive never clones your own voice on the outgoing side of a call.
- You need to review and correct the script before anyone hears it. Post-production tools give you an editing pass; a live dub is spoken once, as it happens.
- You work on a Mac or a phone. The post-production tools run in a web browser. VoxisLive has no macOS or mobile app.
VoxisLive fits when there is nothing to upload: a live stream you are watching, a game with no dub in your language, an international call. Plenty of people will use both — a post-production tool for what they publish, a live dubber for what they watch.
Live Dubbing for Broadcasters
A third group dubs live content at broadcast scale. Deepdub offers live dubbing for broadcasters, with frame-accurate timing and 100+ languages and accents; CAMB.AI dubs live streams in real time for sports, media and entertainment. Deepdub is an enterprise service sold to broadcasters and rights holders. CAMB.AI works with broadcasters too, and its live-dubbing page also invites individual streamers to dub their own YouTube, Twitch or X stream. CAMB.AI has a free plan, but its pricing page does not include live streaming in it: the page lists live streaming only in the $900-a-month Expert plan, beyond that CAMB.AI sells its DubStream product as an enterprise engagement, and the live-dubbing page leads to a demo booking. Neither is an app you install to hear someone else's stream in your language. One name you may still see in older round-ups is Papercup: in 2025 much of its team joined Scale AI, and RWS acquired its dubbing technology for its enterprise localization services. Our live AI dubbing page compares the real-time tools — for broadcasters and for personal listening — side by side.
How to Choose
- Is the content yours, and is it finished? Yes: a post-production tool. No, it is happening live: a live dubber.
- Is a face on screen? If viewers will watch lips, pick a tool with lip-sync — HeyGen, Rask AI, Synthesia or Maestra.
- Whose voice should the dub use? Your own: a voice-cloning tool (ElevenLabs, HeyGen, Rask AI, Synthesia, Maestra, Speechify). The person you are listening to, live: VoxisLive's original-voice mode covers some target languages.
- Which languages? Check your exact language pair on each vendor's list. Headline counts from 60+ to 175+ mix languages, accents and dialects in different ways.
- How do you want to pay? Most post-production tools are monthly or annual subscriptions sized in minutes; VoxisLive sells prepaid minute packs that do not expire while your account is active.
Pricing Models
Post-production dubbing is almost always a subscription. From each vendor's own pricing page in September 2026: on monthly billing, HeyGen from $29 a month, Synthesia Starter at $29 a month and Rask AI Creator at $60 a month, all three cheaper on annual plans; ElevenLabs paid plans start at $6 a month, with dubbing minutes that vary by plan and a small watermarked allowance on the free plan. YouTube auto-dubbing carries no separate charge for eligible creators. VoxisLive sells prepaid minute packs — from 80 minutes for $6.99 to 2,600 minutes for $149.99 — that stack and do not expire while your account is active, on top of the free daily minutes. The units are not comparable one to one: a post-production tool bills per minute of finished video, a live dubber per minute you listen. See VoxisLive pricing for the current packs.
Language counts, input types, features and prices for ElevenLabs, HeyGen, Rask AI, Synthesia, Maestra, Speechify, YouTube, Deepdub and CAMB.AI are taken from each vendor's own public pages, checked on 23 September 2026, not from an independent test.
