Understanding Vietnamese AAC 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 AAC 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 AAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Vietnamese AAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Vietnamese with Sonix:
What is the difference between AAC and M4A files?
Both typically contain the same AAC-encoded audio; the difference is packaging. A .aac file is a raw ADTS stream, while a .m4a file wraps the audio in an MPEG-4 container that supports metadata such as tags, artwork, and chapters.
Why won't my AAC file open in some apps?
Raw .aac files are a bare audio stream without a standard container, so some players and editors that expect MP4/M4A files cannot read them. Renaming the extension does not fix this — remux or convert the file into an M4A or MP3 instead.
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.
Trusted by professionals worldwide
The fact that your service can export text as subtitles and can match the subtitles to the paragraphs in the transcript is just great! Also, the text editor is just awesome. The fact it bonds text and timing in the video so I can check and compare what was pronounced and what was recognized is truly fantastic.
I am very impressed with your program. The recording was not crystal clear and yet I received a perfect transcription...Wow! I would recommend this to anyone.
