Understanding Portuguese FLAC 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 FLAC 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 FLAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese FLAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from FLAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Portuguese with Sonix:
Do I need to convert FLAC to MP3 before transcribing?
No. FLAC files can be uploaded and transcribed directly, and skipping the MP3 conversion avoids an unnecessary lossy re-encode of your audio.
Why won't my FLAC file play in iTunes or Apple Music?
Apple's media apps do not natively support FLAC; Apple uses its own lossless codec, ALAC. You can play FLAC on Apple devices through the Files app or a third-party player, or convert the file to ALAC or AAC for library use.
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.
Trusted by professionals worldwide
I have absolute admiration for the impressive transcription done to 3 short YouTube videos. It is truly amazing how accurately it recorded the correct words and so well paragraphed as well.
I really like it. Easy to use, very accurate, and easy to correct when it is not. A truly super program, and I would recommend it to anyone.
