Thai Text to Speech: Natural Thai AI Voices Fish Audio
Generate Thai that reads the way Thai is actually written: no spaces between words, tone marks and polite particles handled, with the per-project credit math for video, courses and ads. Start from $9 with no subscription.
Thai is written for the ear of someone who already knows the words: the script runs without spaces between words, and the reader segments every sentence on the fly. Tones then decide meaning on top of that — the same syllables in a different tone are a different word. Native-sounding Thai is therefore a segmentation and tone problem before it is a voice problem, and both are fixable in the script before you generate.
This guide covers what to write, what to check, and what a Thai project costs.
What makes Thai different for text to speech?
- No spaces between words. Thai runs words together and the engine segments the sentence the way a reader would. Punctuation becomes your pacing lever: a comma is a breath, a full stop is a landing. Short clauses read cleanly; long unpunctuated runs invite mis-segmentation.
- Tones decide meaning. Thai carries five tones, and changing one changes the word — the classic pair มา (come) and ม้า (horse) is separated by tone alone. Type tone marks correctly, and have a native speaker sanity-check names and rare words.
- Politeness particles set the register. Polite Thai ends sentences with ครับ (male speaker) or ค่ะ (female speaker). Pick the speaker and the register once per script — formal announcements, course narration and casual creator content each hold a different line — and keep it consistent, because mixed particles read wrong even when every word is pronounced perfectly.
- Loanwords and names. Brand names stay in Latin script in everyday writing, and the engine reads them as written. Where the Thai pronunciation should follow the Thai reading of the name, transliterate it into Thai script — that is the highest-value edit for product and place names.
- Numbers and dates. Decide how each figure should be voiced — prices, years, phone numbers — and write it the way it should be said, in the grouping you want read.
Script checklist before you generate
- Punctuate for pacing. Add commas where the narrator should breathe; keep sentences short; one idea per sentence.
- Check tone marks and spelling on names, place names and rare words with a native speaker.
- Pick the speaker and particles. ครับ or ค่ะ, formal or casual — decided once, held to the end.
- Transliterate brand names into Thai script where the Thai reading matters.
- Write numbers as spoken in the grouping you want voiced.
What can you ship with a Thai voice?
- Video — YouTube narration, explainers, TikTok and Reels content for Thai audiences; the short-form guides cover the pacing logic for vertical video.
- Learning — courses and training modules for Thai teams and students; the e-learning guide covers the production loop.
- Ads and product videos — promos where the voice has to sell without sounding like a news broadcast.
- Dubbing — an existing video re-voiced into Thai with the original timing kept; the dubbing guide covers that workflow.
One voice for Thai and its neighbours
Thai stays inside one country but shares patterns with the rest of Southeast Asia: short clauses, listener-first pacing, and content that is watched more than read. A Thai voice can carry a Thai and an English version of the same product, and the same voice reads the Indonesian or English script when the campaign expands — the browser workspace keeps every version in one place.
What does Thai narration cost?
Spoken Thai runs at roughly 100 to 120 words per minute, and one credit covers about 1,000 characters:
| Length | Words | Characters | Approximate cost |
|---|---|---|---|
| 3 minute clip | ~330 | ~2,300 | 3 credits |
| 5 minute segment | ~550 | ~3,300 | 4 credits |
| 10 minute lesson | ~1,100 | ~6,500 | 7 credits |
A video series or a course module set sits far inside one $9 Starter pack. Packs are one-time purchases, credits stay valid for 12 months, and there is no subscription. Monetized channels and client work need the $29 Creator pack for commercial usage rights — the commercial use guide covers what each pack includes.
Frequently asked questions
Does the engine read Thai script directly?
Yes. You paste Thai script as written and the engine segments the sentence into words itself, which is exactly the operation Thai readers do from habit. The quality levers are punctuation for pacing, correct tone marks, and a proof-listen with a native speaker before publishing.
How do I control pacing in a language without word spaces?
Punctuation is the pacing control. Thai runs words together, so commas and full stops are where the narrator breathes. Write shorter clauses than you would in English, place a comma where you want a pause, and keep one idea per sentence.
Can one voice read the Thai and the English version of a script?
Yes. Voices here are not locked to one language: a single voice reads text in 30+ languages, so a Thai-English channel or a bilingual product keeps the same brand voice across both versions.
Can I clone a Thai voice?
Yes, when you have the rights: your own voice, or a speaker who signs a release naming the project and scope. A 15 second recording is enough. Cloning a public figure or a voice actor without permission is not allowed.
What does a Thai voiceover cost?
About 1,000 characters per credit. A five minute narration is roughly 3,300 characters, so about four credits, and the $9 Starter pack holds 1,000 credits. Packs are one-time, credits stay valid for 12 months, and there is no subscription.
