Where Portuguese audio transcription is used
- Brazilian podcast episodes, YouTube content, and influencer audio (massive market)
- European Portuguese (Portugal) corporate communications and academic content
- Lusophone African content from Angola and Mozambique (often with Kimbundu or Emakhuwa code-switching)
- Customer support calls for Brazilian e-commerce and fintech
Challenges of transcribing Portuguese audio
- Brazilian and European Portuguese differ substantially in phonology — Brazilians pronounce unstressed "e" and "o" openly (["tu"] for "ttú"); Europeans close them
- Brazilian colloquial speech uses gerund forms that European Portuguese does not ("estou fazendo" vs "estou a fazer")
- Angolan and Mozambican Portuguese carry strong substrate influences from Bantu languages, affecting rhythm and intonation
Tips for best results
- For Brazilian audio, expect the model to use Brazilian norms in output spelling — this is correct for the target audience
- For European Portuguese recordings, audio clarity matters more than usual — the closed vowels are easier to mishear
- Code-switching with English is common in Brazilian tech content; the model handles it well

Frequently asked questions
- Does the output follow Brazilian or European spelling?
- The model follows the variant of the input audio. Brazilian audio produces Brazilian Portuguese orthography; European audio produces European orthography. The two are mutually intelligible in writing as well as speech.
- Can it handle Brazilian regional accents (Carioca, Paulista, Gaúcho)?
- Yes. All major regional Brazilian accents are well-represented in the training data. Carioca (Rio) and Paulista (São Paulo) are the strongest.
- What about older European Portuguese recordings?
- Modern European Portuguese is well-supported. For pre-1974 recordings (which used different orthographic conventions), the model will transcribe spoken content accurately but spelling follows current norms, not the original orthography.
