Understanding Thai MP3 files
Standard Thai, based on the Central Thai spoken in and around Bangkok, dominates broadcasting, education, and most recorded media, and it is the variety speech recognition models target. Regional varieties — Northern Thai (Kham Mueang), Northeastern Thai (Isan, closely related to Lao), and Southern Thai — differ noticeably in tones and vocabulary, so heavily dialectal recordings typically need more editing.

Frequently asked questions
How to improve the accuracy of your Thai transcripts?
Start by improving the quality of the Thai MP3 file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Thai MP3 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Thai MP3 file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MP3, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Thai with Sonix:
Does the MP3 bitrate affect transcription quality?
It can. Files encoded at 128 kbps or higher preserve more speech detail, while heavily compressed recordings below about 96 kbps may introduce artifacts that make words harder to recognize.
How do I turn an MP3 recording into SRT subtitles?
Upload the MP3, generate a transcript, adjust the text and timings as needed, and export the result in SRT or VTT caption format.
Can Sonix transcribe Thai audio and video files?
Yes. Upload your Thai audio or video file, and Sonix converts it to text that you can proofread in the in-browser editor and export to formats such as Word documents or subtitle files.
Does Thai transcription handle Isan or other regional dialects?
Thai speech recognition is built around Standard (Central) Thai. Recordings with strong Isan, Northern, or Southern dialect speech can still be transcribed, but plan for additional proofreading time in the editor.
Can I create Thai subtitles from my transcript?
Yes. After transcribing and polishing your Thai transcript, you can export it as SRT or VTT subtitle files for video captioning.
