Vietnamese text-to-speech
Turn any script into natural-sounding Vietnamese speech in seconds. Enter your text, choose a voice, and create a studio-quality Vietnamese voice-over or finished video, with no microphone, recording booth or editing required.
Vietnamese text-to-speech features that offer more than audio
Natural Vietnamese voices with six tones
Enter a Vietnamese script and generate natural-sounding speech using a library of over 300 voices across more than 175 languages in the HeyGen AI voice generator. Vietnamese has six tones, so preview male and female voices side by side and choose the delivery that sounds native.
Control tone, pace and emotion
Direct the delivery as you would direct a narrator. The text-based editor gives you control over the tone, pace and emotion of every line, so a compliance script sounds measured whilst a TikTok hook sounds energetic, all using the same Vietnamese text.
Clone your voice in Vietnamese
Record a short sample and AI voice cloning builds a reusable model of your voice that speaks fluent Vietnamese. Keep the same narrator across every lesson, advert and update, rather than paying studio rates for each new recording session.
Turn Vietnamese speech into video
Most Vietnamese TTS tools produce only an MP3. HeyGen combines your generated speech with visuals, captions and an on-screen presenter, transforming a single script into a publication-ready HD or 4K MP4 without cameras, production crews or editing software, suitable for any channel.
Lip-synchronised dubbing into Vietnamese
Already have footage in English? Translate it into Vietnamese with phoneme-level AI lip sync, so mouths match every syllable and the original speaker's tone is preserved. Viewers across Vietnam get a video that feels native, rather than a subtitled afterthought they click away from.
Vietnamese TTS applications, from YouTube to e-learning
Vietnamese YouTube and social media videos
Hiring Vietnamese voice talent for every upload quickly becomes expensive. Write the script, generate the voice-over and let text-to-video create the visuals, so weekly content is published on schedule.
Vietnamese e-learning narration
Training teams across Vietnam usually involves recording sessions and lengthy updates. Generate course narration from text, then update any module by editing the script and regenerating it rather than booking a studio again.
Vietnamese audiobooks and podcasts
Manually narrating long-form audio takes days for each project. Generate chapters of natural-sounding Vietnamese speech, then use audio-to-video conversion to publish podcast episodes on YouTube.
Vietnamese marketing voice-overs
Advertising campaigns need multiple voice-over variants for testing. Generate ten Vietnamese versions in the time previously required for a single studio take, then change hooks and offers for each audience without re-recording anything.
Accessible audio content in Vietnamese
Readers with visual impairments and commuters who listen need audio versions of written content. Convert articles and documents into clear Vietnamese narration so the same material works both on screen and when heard aloud.
Localising global video content into Vietnamese
Global teams often add Vietnamese subtitles and leave it at that, leaving 90 million speakers underserved. Full localisation provides dubbed, lip-synchronised Vietnamese versions of existing videos, which audio-only TTS platforms cannot offer.
How to convert text into Vietnamese speech in four steps
Turn a Vietnamese script into finished audio or video in four straightforward steps, with an initial result ready in minutes.
Paste your Vietnamese script
Type or paste your text into the editor. Vietnamese diacritics and tone marks are fully supported.
Choose a Vietnamese voice
Preview voices and choose the gender, age and delivery style that best suit your audience.
Fine-tune the delivery
Adjust the pacing, pauses and emotion for each line until the delivery sounds as you intended.
Create and share
Render your audio or MP4 video in HD or 4K, then publish it on any channel you use.
What is Vietnamese text-to-speech, and how does it work?
Vietnamese text-to-speech converts written Vietnamese into spoken audio using AI voices trained on native speech. You enter a script, choose a voice, and the engine reads it aloud with the tones and rhythm of a human speaker, with no recording required.
Will AI voices pronounce Vietnamese tones and diacritics correctly?
Yes, modern neural voices read all six Vietnamese tones from the diacritics in your text. Preview a voice using your own script first: words such as ma, má and mả should sound clearly distinct before you commit to a full project.
How do I turn a Vietnamese script into a voice-over video?
Paste your script, choose a Vietnamese voice and select a video layout. HeyGen generates the narration and creates matching scenes, captions and a presenter in one go, turning a text document into a finished video without the need for separate audio and editing tools.
Why choose HeyGen rather than audio-only Vietnamese TTS tools?
Audio-only tools give you an MP3 and stop there. HeyGen take the same script through to a finished video with lip-synchronised narration, captions and translation for other markets, so Vietnamese becomes one output within a complete production workflow rather than the final result.
Can one person realistically produce Vietnamese content at scale?
Yes. Educator Anton Voroniuk produces courses with HeyGen at one-fortieth of the cost, saves 15.5 hours each week and has reached more than 1 million students. A single writer with a script can now maintain a publishing schedule that previously required a studio team.
How much does Vietnamese text-to-speech cost with HeyGen?
You can start for free and generate Vietnamese speech without a credit card. Paid plans start at $24 per month for higher volumes, whilst Enterprise plans include team workspaces and brand controls for organisations publishing Vietnamese content at scale.
Can I clone my own voice to create Vietnamese speech?
Yes. Record a short sample and voice cloning will build a model of your voice that can read Vietnamese scripts. Creators use this to remain recognisable to their audience whilst publishing in a language they do not speak fluently.
Can HeyGen translate my existing videos into Vietnamese?
Yes. Upload a finished video and HeyGen will translate the speech into Vietnamese with lip-syncing whilst preserving the original voice, so you can localise a back catalogue rather than reshoot it. The same process works across more than 175 languages.
Which Vietnamese accent should I choose: Northern or Southern?
Match your audience. Northern delivery is the broadcasting standard used in national media, whilst Southern speech dominates content from Ho Chi Minh City. Preview voices using your script, or clone a native speaker with the accent your viewers expect.
Can I add Vietnamese subtitles to the videos I create?
Yes. The subtitle generator automatically creates timed Vietnamese captions, ensuring videos remain easy to follow without sound and accessible to deaf and hard-of-hearing viewers. Captions also reinforce tone marks for language learners who are following along.
