Understanding Portuguese QT files
Portuguese has two major standards: Brazilian Portuguese and European Portuguese, which differ noticeably in pronunciation, rhythm, and some vocabulary. African varieties spoken in Angola, Mozambique, and other Lusophone countries generally follow the European standard, while Brazil itself has distinct regional accents such as Carioca, Paulista, and Northeastern speech.

Frequently asked questions
How to improve the accuracy of your Portuguese transcripts?
Start by improving the quality of the Portuguese QT 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 Portuguese QT file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese QT file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from QT, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Portuguese with Sonix:
Is a QT file the same as a MOV file?
Both use Apple's QuickTime container format; .qt is the older extension and .mov is the current standard. The contents are structurally the same, which is why most tools treat them identically.
Why won't my QT file open in my media player?
Some modern players only recognize the .mov extension even though the container is the same. Renaming the file from .qt to .mov often restores playback, though very old files may use discontinued codecs that require conversion.
Does Sonix support both Brazilian and European Portuguese?
Yes. You can upload audio or video in either variety, transcribe it, edit the transcript in your browser, and export it in a range of formats.
Can Sonix transcribe Portuguese audio with accented characters?
Yes. Portuguese transcripts include the language's diacritics, such as ã, õ, and ç, and they carry through to exported files.
Can I translate a Portuguese transcript into English?
Yes. After transcribing your Portuguese audio, you can translate the transcript into English or other supported languages and export the result.

Super easy interface, easy to upload and great results.
I loved that Sonix supports so many languages. I've been working on a project that involves speakers of 6 different languages and it allows me to translate everything into English natively, saving me so much time!
