What Portuguese language work involves

Judging translation quality

Deciding whether a translation is accurate and natural — the difference between technically correct and what a Portuguese speaker would actually write.

Transcription and audio

Transcribing Portuguese speech, marking accent and dialect, and flagging where a speech model has misheard.

Cultural review

Catching output that is grammatically fine but culturally wrong: idioms that do not transfer, or register that is too formal or too casual.

Most Portuguese listings ask for native or near-native fluency plus strong English comprehension. A translation qualification helps for the higher-rate specialist work but is rarely required.
