Understanding Portuguese AIFC 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 AIFC 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 AIFC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese AIFC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AIFC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Portuguese with Sonix:
Why won't my AIFC file play on Windows?
Many Windows applications lack decoders for the compression codecs AIFC can contain, such as µ-law, A-law, and G.722. Converting the file to WAV or MP3, or uploading it to a service that decodes AIFC, works around this.
Do I need to convert AIFC to WAV before transcribing?
No. AIFC files can be uploaded directly and are decoded automatically before transcription, so a separate conversion step is not required.
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.
