Understanding Tamil MP4 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 MP4 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 MP4 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Tamil MP4 file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MP4, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Tamil with Sonix:
Do I need to extract the audio from an MP4 before transcribing it?
No. Because MP4 is a container that holds both video and audio streams, the audio track can be read directly from the file, so you can upload the video as is.
Why does my MP4 file play video but no sound?
The file may contain a video stream with no audio track, or its audio may use a codec your player does not support. Checking the file's stream details in a tool like VLC or re-exporting it with an AAC audio track usually resolves the issue.
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.
