Understanding Vietnamese WMV files
Vietnamese has three major regional varieties: Northern (centered on Hanoi), Central (around Huế), and Southern (around Ho Chi Minh City). They differ in tone realization and consonant pronunciation — Northern speech distinguishes six tones while Southern speech merges two of them — so knowing which region your speakers come from helps when reviewing a transcript.

Frequently asked questions
How to improve the accuracy of your Vietnamese transcripts?
Start by improving the quality of the Vietnamese WMV 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 Vietnamese WMV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Vietnamese WMV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WMV, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Vietnamese with Sonix:
Why won't my WMV file play on my Mac?
macOS does not include Microsoft's WMV codecs, so QuickTime cannot open the file natively. You can play it with a third-party app such as VLC, or convert it to MP4 for broader compatibility.
Can I get subtitles from a WMV video?
Yes. After uploading and transcribing the WMV file, you can export the transcript as an SRT or VTT caption file with timestamps aligned to the video.
Can Sonix transcribe Vietnamese audio and video files?
Yes. Upload your audio or video file, select Vietnamese as the spoken language, and Sonix generates a transcript you can edit in the browser and export in formats such as DOCX, PDF, and SRT.
Does Vietnamese transcription include tone diacritics?
Transcripts are written in standard Vietnamese orthography (chữ Quốc ngữ), which includes the tone and vowel diacritics. You can correct any misplaced marks in the built-in editor before exporting.
Does Sonix handle Northern and Southern Vietnamese accents?
You select Vietnamese as a single language, and the transcript covers speech from different regions. Because regional pronunciation varies, it is worth reviewing recordings with strong Central or Southern accents in the editor before export.
