Portuguese words that sound alike
Several Portuguese spelling choices depend on grammar, not sound. The model picks from the sentence, which works on clear speech, and these are the places where a reviewer still finds errors.
- Crase: vou à praia, às 14h, but a partir de and a pé. A missing or extra grave accent is one of the most common slips.
- Por que, porque, por quê and porquê: four forms, one sound. Questions take por que, answers porque, and the end of a sentence por quê.
- Há and a for time: há dois anos (in the past) and daqui a dois anos (in the future).
- Mas and mais, mal and mau, sessão, seção and cessão: check them where the meaning matters.
- Pronoun hyphens: disse-me and dir-se-ia are typical of Portugal, while Brazilian speech mostly puts the pronoun first (me disse). The transcript follows the speaker.
- Lowercase months and days in both varieties under the spelling agreement: novembro, segunda-feira. In Portugal a file is a ficheiro, in Brazil an arquivo, so keep the vocabulary of your reader.
Numbers, phone numbers and money
Portuguese uses a decimal comma and a period for thousands: 3,5%, 10.000 habitantes, R$ 12,50 or 12,50 €. A transcript can contain English-style figures as well, so read every number that will be quoted.
Brazilians often say meia for six when reading phone numbers or codes, short for meia dúzia. A transcript may write the word meia instead of the digit 6, so check phone numbers, CEP codes and order numbers against the audio.
Dates are written 4 de novembro de 2026 or 04/11/2026, day first. Ordinals are 1º and 2ª. Times appear as 14h30 in Brazil and 14:30 or 14h30 in Portugal. If a speaker says duas e meia da tarde, the transcript writes what was said.
Checklist before you send it
With the audio open, go through these points. They cover most of what a teacher, client or editor would notice.
- Check every crase and every por que or porque.
- Check names of people, cities, bairros and companies.
- Look for meia written as a word in phone numbers.
- Make numbers, money, dates and times consistent.
- Decide whether to keep tá, pra and né for a verbatim record or write the full forms.
- For subtitles, read the SRT in your video editor before publishing.
- Turn timestamps or speaker names on or off at export.
Recordings people transcribe in Portuguese
Brazilian students bring interviews for a TCC, mestrado or doutorado. Other common uploads are recorded aulas, the ata of a condomínio meeting, cultos and pregações, podcasts and WhatsApp audios. Speaker labels that show who said what are available on paid plans or with a Minute Pack.
For a TCC appendix, keep timestamps on in the DOCX export so the banca can find each quote in the recording. For an ata, switch them off and keep the speaker names. CSV gives one row per line for coding interviews in a spreadsheet.
