Understanding Thai WMA 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 WMA 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 WMA file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Thai WMA file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WMA, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Thai with Sonix:
Why won't my WMA file play on my Mac or iPhone?
WMA is a proprietary Microsoft format, and Apple devices do not support it natively. You can play the file in a third-party app such as VLC, or convert it to a widely supported format like MP3 or M4A.
Does converting WMA to MP3 reduce audio quality?
Both formats are lossy, so re-encoding a WMA file to MP3 adds a second compression pass that can introduce minor quality loss. For speech recordings at typical bitrates, the difference is usually not noticeable.
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.
