Understanding Portuguese WMV 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 WMV 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 WMV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese WMV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WMV, 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 WMV file play on my Mac?
macOS does not include Microsoft's WMV codecs, so QuickTime cannot open the file natively. You can play it with a third-party app such as VLC, or convert it to MP4 for broader compatibility.
Can I get subtitles from a WMV video?
Yes. After uploading and transcribing the WMV file, you can export the transcript as an SRT or VTT caption file with timestamps aligned to the video.
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.
