Translate Spanish Audio to English: Text, Subtitles & Transcripts (2026)

Upload the Spanish audio (MP3, WAV, M4A) or video file (MP4, MOV). VexaScribe: upload → language auto-detects as Spanish → set target to English → download as TXT, DOCX, SRT (subtitles for video), or VTT (HTML5 web video). Under the hood, VexaScribe runs two stages: (1) Spanish transcription — Standard tier uses Whisper Large-v3 (1 credit per audio minute), Premium tier uses a proprietary higher-accuracy model (2 credits per audio minute) for noisy, quiet, or accented Spanish. (2) English translation — Standard tier is free via Google Translate, Premium tier uses our internal translation model for professional-grade output. Processing time is roughly equal to audio length. Free tier: 30 minutes on signup, no credit card.

Text output means you get English words as a written transcript, subtitles (SRT/VTT), or a Word document — you read it or overlay it as captions on the original Spanish video. Dubbed audio means AI generates new English speech that replaces the original Spanish voice — you hear an AI voice reading the English translation aloud. VexaScribe outputs text and subtitles only. For AI-generated dubbed English audio, use ElevenLabs, Maestra, or Rask AI — those specialize in voice cloning and dubbing.

Two stages: Spanish transcription (measured 1.2% WER on clean FLEURS-ES with GPT-4o Mini, 2.9% WER on accented CommonVoice-ES with AssemblyAI Universal-3.5 Pro in our July 2026 benchmark) + English translation (neural MT on Spanish↔English hits 25–35 BLEU on standard test sets — publication-grade). Combined pipeline typically produces 90–96% word-level accurate English text on clean Spanish audio. Accuracy drops on heavy regional slang, poor microphones, background noise, code-switching, and music-heavy audio.

Yes. Whisper Large-v3 was trained on ~11,100 hours of multilingual Spanish audio covering Iberian, Mexican, Colombian, Argentine, Chilean, Caribbean, and other Latin American varieties. Mexican Spanish transcribes strongest (largest training data share). Chilean informal register is the hardest of the majors due to rapid speech and heavy slang. Caribbean varieties transcribe well but rapid speech occasionally causes misses.

Two paths. (1) Use our YouTube transcript tool with translate-to-English enabled — paste the URL, get English subtitles back. (2) Download the Spanish video, upload it here, select translate-to-English. Path 1 is faster for videos with existing captions; path 2 works even when captions are disabled and gives higher accuracy on accented speech via Whisper's re-transcription.

Audio: MP3, WAV, M4A, OGG, FLAC, AAC, AMR, OPUS. Video: MP4, MOV, WebM, MKV, AVI, WMV, FLV. Maximum 5 GB per file — roughly 5 hours of standard audio or 2–3 hours of 1080p HD video. Video files: the audio track is extracted server-side, no ffmpeg step needed on your end.

Yes. Upload the Spanish video, choose translate-to-English, download the SRT (universal subtitle format) or VTT (HTML5 web video). Drop the SRT into Premiere Pro, Final Cut, DaVinci Resolve, or upload directly to YouTube as an English subtitle track. Timestamps are preserved from the original Spanish speech timing.

Google Translate handles text-to-text and short voice snippets in real-time conversation mode. It doesn't accept file uploads longer than a few minutes and doesn't produce SRT/VTT subtitle files. We handle file uploads up to 5 hours, output structured formats (TXT, DOCX, SRT, VTT), and preserve speaker labels when your audio has multiple voices. For a quick spoken phrase, use Google Translate app. For a recorded interview, meeting, or video, use a file-upload tool like ours.

Yes. VexaScribe runs a two-stage flow regardless of direction: transcribe first (Whisper Large-v3 Standard, or our Premium model for higher accuracy), then translate the resulting text via our translation stage (Standard free tier or Premium paid tier). For English→Spanish: upload English audio, set target to Spanish, download. Same input formats, same output types (TXT, DOCX, SRT, VTT). Quality is comparably high on this well-resourced language pair. Note: same as Spanish→English, output is text and subtitles only — for dubbed Spanish audio, use ElevenLabs or Maestra.

Audio files are processed for transcription and translation, then retained only as long as needed to deliver the result. See our privacy policy for full retention and deletion terms. For highly sensitive audio (legal, medical, journalistic sources), the safest option is self-hosted Whisper on your own hardware — free, MIT license, requires Python setup. VexaScribe is a hosted service and audio touches our servers; that trade-off is real. Choose based on your sensitivity requirements.

Yes on the VexaScribe free tier — 30 minutes of transcription + translation on signup, no credit card. Translation itself is included at no extra cost on every plan (Free through Studio). For creator-scale workflows (5–20 Spanish clips/week), the free tier plus a $2 Starter plan covers typical usage without hitting limits.

Any audio file where the primary language is Spanish (Iberian, Mexican, Argentine, Chilean, Caribbean, or other regional variety). MP3, WAV, M4A, OGG, FLAC, AAC, AMR, OPUS all work. Video files (MP4, MOV, WebM, MKV) work directly — audio track extracted server-side. Max 5 GB per file (~5 hours of audio). For mixed-language content (Spanglish, code-switching), Whisper handles it but accuracy drops — consider recording separate segments if practical.

Same workflow as any Spanish audio: upload the podcast episode (MP3 typical, WAV for lossless), set source = Spanish (auto-detects), target = English. Full 60-minute episode processes in ~60 minutes. Export as DOCX for editing, TXT for pasting into show notes, or SRT for creating English subtitles on a video version. Speaker labels work when the podcast has 2–4 clearly-separated voices.

Same tool, different framing. 'Voice translator' typically implies short conversational spoken clips (WhatsApp voice notes, short recordings). 'Speech translator' implies conversational recordings. 'Audio translator' implies longer files (podcast episodes, interviews, meetings). VexaScribe handles all three under one workflow — upload the file, pick target language, download translated text. The keyword you searched routes to the same page because the underlying job is identical: Spanish spoken content → English text.

WhatsApp exports voice notes as .opus or .m4a files. Long-press the voice message → Share → Save to Files (iOS) or Save (Android). Upload the exported file to VexaScribe, source auto-detects as Spanish, target = English. Get English text back in under a minute. Especially common workflow for adults processing voice notes from Spanish-speaking parents, LATAM business contacts using WhatsApp, or diaspora family communication.

Upload English audio (MP3, WAV, M4A, MP4, MOV), set source = English (auto-detects), target = Spanish. Same 5-step workflow. Output defaults to neutral Spanish (works for both LATAM and Iberian audiences). For LATAM-specific vs Iberian Spanish output preferences, the translation stage produces standard Spanish that reads naturally in both markets for most content. Export as TXT, DOCX, SRT, or VTT.

Yes. 'Translate spanish to english audio', 'translate spanish audio to english', 'audio translation spanish to english', 'spanish audio translator to english', 'translate audio spanish to english' — all searches route to this workflow because the underlying job is the same: Spanish spoken content to English text. Different word orders are just different ways users phrase the same query.
