Understanding Catalan MP4 files
Catalan splits into two broad dialect blocks: Eastern (including Central Catalan spoken around Barcelona, Balearic, and Alguerese in Sardinia) and Western (including Valencian, officially called Valencian in the Valencian Community). Eastern varieties reduce unstressed a and e to a schwa and unstressed o to u, while Western varieties keep these vowels distinct — a difference that affects how words sound in recordings.

Frequently asked questions
How to improve the accuracy of your Catalan transcripts?
Start by improving the quality of the Catalan 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 Catalan MP4 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Catalan 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 Catalan 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 Valencian audio?
Yes. Valencian is a variety of Catalan, so you can upload Valencian audio or video, transcribe it with the Catalan model, and edit the transcript in your browser.
Does Catalan transcription work if speakers mix in Spanish?
Occasional Spanish words and phrases are common in Catalan recordings and can appear in the transcript, but heavily mixed audio should be reviewed in the editor. If a recording is mostly Spanish, transcribe it as Spanish instead.
Can I create Catalan subtitles from my video?
Yes. After Sonix transcribes your Catalan video, you can export the transcript as SRT or VTT subtitle files, with every word individually timestamped.
