Understanding Portuguese WAV 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 WAV 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 WAV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese WAV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WAV, 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 WAV to MP3 before transcribing?
No, WAV files can be uploaded and transcribed directly. Keeping the original WAV avoids the compression artifacts an MP3 conversion introduces, though the larger file may take longer to upload.
Why are my WAV files so large?
WAV stores uncompressed PCM audio, so CD-quality stereo uses roughly 10 MB per minute. Converting to a compressed format like FLAC or MP3 reduces the size if you need to save space after 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.
Trusted by professionals worldwide
After trying a number of MP3 transcribers, I am most impressed with Sonix! It was easy to use and was much more accurate than any of the others that I tried.
