Thai audio to text: an honest view
Thai is supported, but the speech model has much less Thai training data than it has for major European languages. A clear recording of one speaker close to the microphone usually gives a draft that needs moderate editing. Phone calls, noisy restaurants and markets, music underneath, and several people talking at once will need much more correction.
Formal Thai in news, lectures and presentations comes out cleanest. Fast casual speech, slang and strong regional accents need the most checking. Plan to review names of people and places, company names and technical terms in every transcript.
The editor is built for that review. The player highlights the current line, you click any line to hear it again, and you correct the text in place.
Thai script, spacing and tones
Written Thai does not put spaces between words. Spaces usually mark the end of a phrase or sentence instead, and Thai rarely uses a full stop. The transcript follows Thai script, but where it places spaces and line breaks is decided by the model and the timing of the speech, so it can look different from how you would type the same sentences. Some lines may be long runs of text and others may break mid-thought.
Tone in Thai is spelled through a combination of the consonant, the vowel and the tone marks. When the model mishears a tone or a vowel length, it writes a different word that can look correct at a glance. Read with the audio running and watch for words that do not fit the sentence.
- Names of people and places are where most corrections happen, especially when several spellings are possible.
- Numbers, dates and amounts in baht may appear as digits or spelled out in Thai.
- Polite particles such as ครับ and ค่ะ and short fillers may be kept, dropped or written in a different form.
- Subtitle files take their line breaks from the transcript, so review long lines before exporting SRT or VTT.
Thai-English mixing and regional speech
Thai speakers mix in many English words, especially for technology, business and school subjects. These may come out in Latin letters or written in Thai script the way they sound, and the same word can appear both ways in one file. If you need a consistent document, plan a quick pass to bring them into one form.
Central Thai, close to what is heard on Bangkok television, works best. Northern, southern and Isan speech are harder, and when a speaker shifts fully into a regional language the transcript will try to write it as standard Thai and miss words. Isan is close to Lao, and Lao is a separate option in the language list, so auto-detect can confuse the two. This page preselects Thai so that guess is skipped. Auto-detect can also misjudge short voice notes and clips that open in English.
Choose the language by what dominates the recording. If it is a Thai meeting with English terms, keep Thai. If it is an English call with a few Thai sentences, choose English for that file.
Who uses Thai transcription
Common uploads include calls with suppliers and partners in Thailand, user research and market research interviews, university lectures, temple talks and dhamma recordings, podcasts, and YouTube or TikTok videos that need Thai subtitles. Thai communities in the US, the UK, Australia and Europe record family stories for relatives who read Thai less easily than they speak it.
You do not need to convert anything first. MP3, M4A and WAV files, phone videos in MP4 or MOV, and WhatsApp or Telegram voice notes all upload directly. Recording close to the speaker and away from fans, traffic and music makes a bigger difference for Thai than any setting.
Exports and reading it in English
TXT, DOCX for Word, PDF, SRT, VTT and CSV keep the Thai script as written. Speaker labels are available on paid plans or with a Minute Pack, which helps with interviews and group calls.
