YouTube now lets one video carry several audio tracks. That makes AI dubbing the cheapest way to reach viewers in other languages without opening new channels. Choosing a tool is harder than it looks, though. Prices are metered in credits, the features that matter for YouTube are often locked to higher plans, and many tools handle English well but other source languages poorly. This comparison looks at six options from the angle of a creator who does not publish in English and wants extra language tracks on existing videos.

Prices and features were checked on each provider’s official pricing page and documentation on October 5, 2026, in USD. They change often, so confirm before you buy. We have measured YouTube’s auto-dubbing on our own channel. The paid tools below are compared on their documented features and prices. Our hands-on dubbing test starts with ElevenLabs, and we will add the results here.
Quick picks
- Free starting point: YouTube auto-dubbing. It is automatic, but a non-English channel only gets an English track.
- Best for YouTube audio tracks: ElevenLabs. It clones your voice, accepts Vietnamese as source and target, and exports a ready-to-upload audio file. About $0.50 to $0.60 per dubbed minute.
- Lowest cost per minute and best lip sync: HeyGen. From about $0.19 per minute (audio-only dubbing), with lip sync for on-camera videos. On self-serve plans you download a full video, not an audio track.
- Also worth a look: VEED for creators who already edit in VEED, Synthesia for teams, and Rask AI if you need separate voice and background audio files.
What matters when you dub for YouTube
For YouTube’s multi-language audio feature, you upload an audio file for each language to your existing video. That changes what you should look for:
- Your source language must be supported. Many tools list 100+ target languages but fewer source languages. Check yours, especially if it is not English.
- Audio-only export. The ideal output is a clean audio track that matches your video’s timing. A full dubbed video works too, but you have to extract the audio yourself.
- Voice cloning, so the dub still sounds like you.
- Editable translation. Names, product terms and jokes need fixing before the voice is generated.
- Cost per dubbed minute per language. A 10-minute video into three languages is 30 dubbed minutes.
Lip sync matters for talking-head videos. For screen recordings and faceless content, it does not.
Comparison table
| Tool | Vietnamese as source | Voice clone | Lip sync | Audio-only export | Cheapest plan with ongoing dubbing | ≈ Cost per dubbed minute |
|---|---|---|---|---|---|---|
| YouTube auto-dubbing | Yes, into English only | No | Pilot, selected channels | Not needed (built in) | Free | $0 |
| ElevenLabs | Yes (source and target) | Yes | No | Yes (lossless audio) | Starter $6/mo | $0.50–0.60 |
| HeyGen | On the language list* | Yes | Yes | Enterprise only | Creator $29/mo | $0.19 audio only, $0.29–0.48 with lip sync |
| VEED | Not confirmed in docs* | Yes (per video) | Yes (beta) | Not confirmed | Pro $257/yr | ≈ $0.71 |
| Synthesia | Yes | Yes | Paid plans | Not confirmed (MP4) | Starter $216/yr | ≈ $1.10 |
| Rask AI | Target confirmed, source not in docs* | Yes | From Creator Pro | Yes (voice only, or voice + background) | Creator $39/mo | $1.10–1.56 |
* Supported according to the provider’s language list or marketing page, but the help docs do not separate source from target languages. Run a short test with your own language first. Costs are the plan price divided by the dubbing minutes it includes, without watermark, on the cheapest qualifying plan.
1. YouTube auto-dubbing: the free baseline
YouTube dubs eligible videos automatically, with no extra cost and no work. The catch for non-English creators: English videos can be dubbed into 20 languages, but videos in 29 other languages, Vietnamese included, can only be dubbed into English. There is no voice clone, and videos with copyright claims, very fast speech or little speech are skipped.
On our Vietnamese channel the English auto-dub brought 0.2% of watch time in the first 28 days. It is a useful start, not a strategy. Our YouTube auto-dubbing guide covers setup, and the case study tracks the results.
Use it for: the English track. Turn on manual review and fix the translated titles.
2. ElevenLabs: best for YouTube audio tracks
ElevenLabs’ automatic dubbing supports 90+ languages, and Vietnamese appears in its language table, so it works for Vietnamese-to-Spanish or Vietnamese-to-Indonesian. It clones each speaker so the dub keeps their tone and pace, and the result downloads as a single lossless audio file that you can upload as a YouTube audio track. That makes it the most direct fit for the multi-language audio workflow.
- Price: automatic dubbing uses 3,000 credits per minute per language without watermark (2,000 with). Starter ($6/mo, 30,000 credits) covers about 10 minutes, about $0.60 per minute. Creator ($22/mo, 121,000 credits) covers about 40 minutes, about $0.55 per minute. The free plan allows about 5 watermarked minutes. Note: ElevenLabs’ newer dubbing documentation describes per-minute US dollar pricing for its latest dubbing model (via the API, about $2.20 per minute), while the pricing page meters dubbing in credits. Check the cost shown in the app before a long job.
- Editing: the older Dubbing Studio lets you edit the transcript and translation line by line. It is in maintenance mode, limited to 45-minute videos, and costs more (10,000 credits per minute without watermark). Transcript editing in the newer automatic dubbing is API and Enterprise only.
- Limits: up to 180 minutes per video in the app. No lip sync.
Best for: screen recordings, tutorials and faceless videos where voice quality matters more than lip movement. This is the tool we are testing first.

3. HeyGen: lowest cost per minute, best lip sync
HeyGen’s Video Translate supports 175+ languages and dialects on paid plans (30+ on Free). It clones the original speaker’s voice and offers two lip-sync modes, Speed and Precision.
- Price: Creator costs $29/mo ($24/mo yearly) with 600 credits. Dubbing uses 4 credits per minute for audio only, 6 with Speed lip sync and 10 with Precision lip sync. That works out to about $0.19, $0.29 and $0.48 per minute. Creator allows videos up to 30 minutes, Business up to 60.
- Editing: the review and edit step for the translation needs Pro ($49/mo) or above.
- The YouTube catch: audio-only download is Enterprise only. On Creator and Pro you download the dubbed video and extract the audio track yourself, with any free editor.
Best for: talking-head videos where lip sync is worth it, and creators who dub a lot of minutes every month.
Full details in our HeyGen review.
4. VEED: dubbing inside a video editor
VEED adds AI dubbing to its browser video editor. It accepts 70+ source languages, clones the original voice (a new clone per video), and offers lip sync in beta on all plans.
- Price: ongoing dubbing starts on Pro ($257/yr, 6 hours of dubbing a year), about $0.71 per minute. Creator and Free only include a one-time try.
- Limits: proofreading the translation is Enterprise only. Vietnamese appears on a marketing page, not in the help docs, and we could not confirm an audio-only export.
Best for: creators who already edit in VEED and want subtitles, dubbing and editing in one place.
5. Synthesia: for teams and training videos
Synthesia is best known for AI avatars, but it also dubs uploaded videos (or a YouTube link) and clones the original voice automatically. Vietnamese is supported as a source and as a target on self-serve plans.
- Price: Starter is $18/mo billed yearly ($216/yr) with “up to 197 minutes” of dubbing a year, about $1.10 per minute. The free Basic plan includes a few watermarked minutes. Synthesia’s pages give different credit rates for dubbing, so check the calculator for your case.
- Limits: translation editing is Enterprise only. Downloads are MP4, so plan to extract the audio for YouTube.
Best for: companies already using Synthesia for training or product videos.
6. Rask AI: clean audio exports, higher price
Rask AI translates into 130+ languages, with voice cloning in about 32 of them (Vietnamese included). It has the most practical exports for YouTube: you can download “audio with voice only” or “audio with voice and background”, plus subtitle files.
- Price: Creator is $39/mo for 25 minutes (about $1.56 per minute), or $329/yr for 300 minutes (about $1.10 per minute). Lip sync starts on Creator Pro ($99/mo). The free trial is 3 minutes.
- Limits: its help docs do not confirm which languages are accepted as source. Test yours.
Best for: creators who want separate voice and background tracks to remix the audio themselves.
What one video in three languages costs
Example: a 10-minute video dubbed into Spanish, Portuguese and Indonesian is 30 dubbed minutes. Using each tool’s stated monthly allowances (October 2026):
| Tool | Plan that covers 30 min a month | Price |
|---|---|---|
| HeyGen (audio only) | Creator (about 150 min) | $29/mo |
| ElevenLabs | Creator (about 40 min) | $22/mo |
| VEED | Pro (6 h a year, about 30 min a month) | $257/yr |
| Synthesia | Pro (up to 947 min a year) | $64/mo billed yearly |
| Rask AI | Creator Pro (100 min) | $99/mo |
For a creator who dubs a few videos a month, HeyGen and ElevenLabs are in the same price range. The difference is the workflow: ElevenLabs gives you the audio track directly, HeyGen gives you lip sync.
How to choose
- You publish in English: start with YouTube’s free auto-dubbing (20 languages), then use a paid tool only where quality matters.
- You publish in another language and record your screen or voice-over: ElevenLabs, because you get a cloned voice and an audio file ready for YouTube.
- You are on camera: HeyGen, for lip sync at a low price per minute.
- You already use VEED or Synthesia: try their dubbing before adding another subscription.
Whatever you pick, dub one video first, listen to it with a native speaker, and write the translated title and description yourself. Those make more difference to discovery than the voice.
FAQ
What is the cheapest way to dub YouTube videos?
YouTube’s auto-dubbing is free, but it only goes from English into 20 languages, or from other languages into English. For anything else, HeyGen’s audio-only dubbing (about $0.19 a minute on Creator) and ElevenLabs (about $0.50 to $0.60 a minute) are the cheapest options in this comparison.
Can I upload an AI dub to my existing YouTube video?
Yes, with multi-language audio: in YouTube Studio open the video → Languages → Add language → Audio, and upload the dubbed audio file. YouTube has been rolling the feature out to most channels.
Do I need lip sync?
Only if your face is on screen for long stretches. For tutorials, screen recordings and faceless videos, a natural voice matters more.
Which tools support Vietnamese?
ElevenLabs and Synthesia confirm Vietnamese as source and target in their documentation. HeyGen, Rask AI and VEED list Vietnamese but do not separate source from target in their docs, so test with a short clip first.
