Understanding Tamil AU files
Tamil shows strong diglossia: formal written Tamil differs markedly from the colloquial Tamil heard in everyday conversation and media. Regional variants — Tamil Nadu dialects in India, Sri Lankan Tamil (including the conservative Jaffna dialect), and Malaysian/Singaporean Tamil — differ in pronunciation and vocabulary, which is worth knowing before transcribing spoken audio.

Frequently asked questions
How to improve the accuracy of your Tamil transcripts?
Start by improving the quality of the Tamil AU 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 Tamil AU file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Tamil AU file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AU, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Tamil with Sonix:
Why is my Audacity project folder full of small AU files?
Older versions of Audacity split a project's audio into small AU block files inside a _data folder so long tracks could be edited efficiently, and the .aup project file reassembles them in order. Avoid moving or renaming these chunks; open the project and export the audio instead.
How do I play a standalone AU file?
Standalone AU files use the Sun audio format and open in players such as VLC and editors such as Audacity. Converting to WAV or MP3 gives the broadest compatibility with modern software and devices.
Can Sonix transcribe Sri Lankan Tamil as well as Indian Tamil?
Yes. Sonix's Tamil transcription accepts audio and video from India, Sri Lanka, Singapore, and diaspora communities — upload the file, select Tamil, and review the transcript in the built-in editor.
Does Sonix output Tamil transcripts in Tamil script?
Yes, transcripts are generated in Tamil script and can be exported to formats such as DOCX, PDF, SRT, and VTT.
Can Sonix handle Tamil audio that mixes in English words?
Tamil-English code-switching is common in Tamil media and everyday speech. Select Tamil as the transcription language, then use the AudioText Editor to correct any mixed-language passages before exporting.

The transcription was pretty darn good!
Really fast to transcribe our audio files with high accuracy, we just had to correct some small words. I like the layout of the website, how pleasing to the eye and easy it is to edit your files, nothing was complicated and I wasn't ever 'stuck' on something and didn't know where to click etc, it was my first time ever using something like this and it was a breeze!
