Understanding Portuguese AIF 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 AIF 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 AIF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese AIF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AIF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Portuguese with Sonix:
What is the difference between AIF and AIFF files?
They are the same Audio Interchange File Format; .aif is simply the shortened three-character extension. Any application that opens AIFF files can open AIF files.
Why are my AIF files so large?
AIF stores uncompressed PCM audio, so a CD-quality stereo recording takes roughly 10 MB per minute. The upside is that no audio detail is lost to compression, which also makes the files well suited to transcription.
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.

My transcript work flow is so fast now. It takes me half the time it used to. So glad i found you :)
The entire process is extremely straightforward and what I liked most was the accuracy of the transcriptions and translations. I must say, I had some doubts as to what the quality would be like since it was in French, but I was not disappointed in the least.
