Transcribe Portuguese Audio to Text

• Transcribe Portuguese audio with no language picker

  Most tools make you choose a language and a dialect before you start. EchoWave's speech recognition detects Portuguese automatically the moment your file is processed, so a São Paulo podcast and a Lisbon lecture both come out right. If a clip is ever misread, a manual source-language override is there after transcription.

• Brazilian and European Portuguese, both covered

  European Portuguese compresses unstressed vowels, which is why AI tools trained mostly on Brazilian speech tend to stumble in Lisbon. EchoWave transcribes both variants; for pt-PT recordings, a close microphone and low background noise make the biggest difference. Every word stays editable afterwards, so a misheard term takes seconds to fix.

• Word-level timestamps on every word

  Each word in the transcript carries its own timestamp rather than one per sentence. That is what makes precise subtitle timing possible, and it powers karaoke-style captions where the active word fills with color as it is spoken.

• Edit the video by editing the text

  Delete a sentence in the transcript and the matching stretch of video is cut. Hesitation sounds and silences can be removed automatically, and Portuguese fillers like né, tipo and então come out by deleting the words themselves. Our video to text page walks through that workflow in depth.

• From transcript to styled Portuguese subtitles

  Convert the transcript into subtitle cues on the timeline and style them with 176 caption presets, including word-by-word karaoke looks. Diacritics like ã, ç, õ and ê render natively in every preset. For a captions-first workflow, see the Portuguese subtitle generator.

• TXT, JSON, SRT and VTT on paid plans

  On a paid plan, download the transcript as plain TXT for articles and podcast show notes, or as JSON with timestamps for developers. Subtitles download as SRT or VTT, all UTF-8, so ã, ç and õ survive the trip into any other app. You can also import an existing SRT or VTT file and edit it here for free.

• Translate into 86 languages

  Once the Portuguese transcript is right, translate the subtitles into English, Spanish, French or any of 86 languages, a Pro feature. Bilingual mode shows Portuguese and the translation on screen together, which language teachers and international channels use constantly. Translation changes the subtitle text only; it does not re-voice the audio.

• Add a Brazilian Portuguese voice over

  Need narration over the footage? EchoWave's text to speech includes 3 Brazilian Portuguese voices, 1 female and 2 male, among 63 voices in total. Type or paste a script, generate the voice over inside the same editor, and line it up on the timeline next to your captions.

1. 1

   Upload your Portuguese recording

   Drag in audio (MP3, WAV, M4A and more) or video in any of 20 formats, including MP4, MOV, MKV, AVI and WebM. Upload from a Mac, Windows, Linux or Chromebook browser.

2. 2

   Run AI transcription

   Open the captions panel and generate the transcript. The AI detects Portuguese on its own, Brazilian or European, and returns every word with its own timestamp. If anything is misidentified, set the source language manually after the first pass.

3. 3

   Correct and clean up

   Click any word to fix it, which matters for names like Guimarães or brand terms the AI has never met. Remove silences and hesitations automatically, and delete fillers like né or tipo straight from the text to cut them from the recording.

4. 4

   Export the transcript or subtitles

   On a paid plan, download TXT or JSON for the transcript and SRT or VTT for subtitles. You can also burn styled captions into the video. Video exports are free at 720p MP4 with a small EchoWave badge and a short end card; paid plans remove them, raise quality to 1080p and 4K and add audio-only MP3, WAV and M4A exports.

• Podcasts and show notes

  Brazil has one of the largest podcast audiences in the world, and transcripts are how episodes get found on Google. Turn each episode into a searchable page, pull quotes for social posts, and keep a written archive of every conversation.

• Interviews and journalism

  An hour-long interview becomes text you can search and quote, with a timestamp on every word. Reporters covering Brazil and Portugal use transcripts to verify quotes before publishing.

• Short-form video for Brazil

  Most Reels, TikToks, Shorts and Kwai clips play muted, and Brazil is one of the biggest audiences on all four. Transcribe the clip, style karaoke captions in Portuguese, and burn them in before posting.

• Lectures and study notes

  Students in Coimbra or Campinas can turn a two-hour recorded aula into notes they can search the night before an exam. Word timestamps make it easy to jump back to the exact moment a concept was explained.

• Meetings and calls

  Upload a recorded meeting and get the discussion in writing without typing a word of it. Search for the decision, copy the exact phrasing, and paste it into your notes or a follow-up email.

• Reaching beyond Portuguese

  Portuguese is an official language in nine countries, and a transcript is the bridge to everyone else. Translate the subtitles into English or Spanish, or show bilingual captions so one video serves São Paulo and San Francisco at once.
