Regional Spanish handling
Whisper Large-v3 was trained on multilingual audio covering all major Spanish varieties. Accuracy varies by dialect representation in the training corpus.
| Variant | Accuracy (clean audio) | Notes |
|---|---|---|
| Mexican Spanish | 93-95% (strongest — largest training corpus) | Reference variant for most Latin American media; recording ideal. |
| Peninsular (Spain) | 93-95% | Strong across Iberian dialects. Distinctive 'th' (ceceo/seseo) handled well. |
| Rioplatense (Argentina, Uruguay) | 90-93% | Voseo forms ("vos sos") and yeísmo transcribed correctly; check technical terms. |
| Colombian | 91-94% | Highland Colombian is very clear; coastal Colombian closer to Caribbean. |
| Andean (Peru, Bolivia, Ecuador) | 90-93% | Solid — Quechua-influenced sentence structures handled reasonably. |
| Caribbean (Cuba, PR, DR) | 85-90% | Consonant elision ("pescao" instead of "pescado") can drop 3-5 pp; expect proper-noun errors. |
| Spanglish / code-switching | Variable | Whisper picks dominant language and handles switches; single-language output. |
For any variant, expect 5-10 minutes of manual review per audio hour to fix proper nouns, brand names, and dialect-specific idioms. See how accurate is Whisper for benchmark methodology.
Accuracy expectation (honest)
Stage 1 — Spanish transcription: Whisper Large-v3 hits 93-95% word accuracy on clean Spanish audio per the FLEURS benchmark. Dialect-heavy or noisy recordings drop to 88-92%. Dense Caribbean consonant elision or heavy Andean accent can go lower.
Stage 2 — Spanish → English translation: Around 90% BLEU on general content. Accurate for meaning and natural sentence structure. Where it fails: heavy domain jargon (medical, legal, technical), dense idiomatic speech (\"echar de menos,\" \"hacer un puente\"), poor source audio quality, and proper nouns.
Budget review time. For publication-grade output — journalism, published research, subtitles for large audiences — expect 5-10 minutes of manual review per audio hour to fix proper nouns, idiom translations, and dialect-specific corrections. For internal notes, meeting summaries, or personal archives, the raw output is usually good enough.
Not suitable without expert review: certified court translation, medical patient records, legal contracts, or any context where a mistranslation carries liability. For those, use a certified translator.
This tool: text + SRT output. Not voice dubbing.
VexaScribe produces translated text and subtitle files (TXT, DOCX, SRT, VTT, JSON). We do not produce voice-cloned dubbed audio in the target language.
For voice-cloned dubbing (English audio spoken in the original Spanish speaker's voice, or in a synthetic English voice), see specialized dubbing tools like Maestra or ElevenLabs. Different product category, different pricing, and different ethical considerations (voice-clone consent, deepfake potential).
Choose this tool when you need: accurate translated text for reading, timed English subtitles for a video, a bilingual reference document, or a translation-memory-compatible export. Choose a dubbing tool when you need: spoken English audio, video dubbing for narration, or accessibility for audiences that can't read subtitles.
Pricing compared (verified July 2026)
For a one-off Spanish audio translation, the free tiers are the deciding factor. For ongoing multilingual workflows, per-minute effective cost matters.
| Tool | Free tier | Paid pricing | Notes |
|---|---|---|---|
| VexaScribe | 30 min (no card) | $2-20/month | EU hosting, 99 languages, bilingual output |
| HappyScribe | 10 min | €15-72/month AI | EU option available; 99% human tier at €1.40/min |
| Maestra | 10 min | Per-minute pricing | Focuses on voice-cloned dubbing; text output also available |
| Rev (AI + human) | None | $1.99/min | Highest accuracy via human review; 12-24h turnaround |
| Google Translate | Live only | N/A | Not designed for uploaded audio files; use conversation mode only |
For a single Spanish audio file under 30 minutes, VexaScribe's free tier is genuinely enough. For a multi-hour interview archive or ongoing multilingual studio work, the $5/month Basic tier at 1,000 minutes is the honest fit.

Frequently asked questions
How do I translate a Spanish audio file to English?
Three steps. (1) Upload your Spanish audio file — MP3, M4A, WAV, OPUS, OGG, FLAC — up to 5 GB and 10 hours. (2) VexaScribe runs Whisper Large-v3 on the Spanish audio (93-95% word accuracy on clean audio), then translates the transcript to English. Processing takes 5-15 minutes for a 60-minute recording. (3) Download the English translation in TXT, DOCX, SRT, VTT, or JSON. You also get the original Spanish transcript in a bilingual side-by-side view for verification. First 30 minutes free, no credit card required.
How accurate is Spanish audio to English translation?
Two stages, two accuracy floors. (1) Spanish transcription: Whisper Large-v3 hits roughly 93-95% word accuracy on clean Spanish audio (FLEURS benchmark). Regional variants vary — Mexican and Peninsular Spanish score highest; heavily accented Andean or Caribbean dialects drop 3-8 percentage points. (2) Spanish→English translation: general content lands around 90% BLEU — accurate for meaning, natural in sentence structure. Where it drops: heavy domain jargon (medical, legal, technical), dense idiomatic speech, poor audio quality. For publication-grade output, budget 5-10 minutes of manual review per audio hour to fix proper nouns and idioms.
Which Spanish variants are supported?
All of them — Whisper Large-v3 was trained on multilingual audio including all major Spanish varieties. Practical accuracy note: Mexican Spanish (the largest Spanish-speaking audience) has the strongest training representation, followed by Peninsular Spanish (Spain), then Rioplatense (Argentina, Uruguay), Colombian, and other Latin American varieties. Caribbean dialects (Cuba, Puerto Rico, Dominican Republic) with heavy consonant elision may drop 3-5 accuracy percentage points. Andean Spanish (Peru, Bolivia, Ecuador, Colombian highlands) transcribes well. Spanglish and code-switching (Spanish + English mixed in the same clip) work reasonably — Whisper picks the dominant language and handles the switches.
Is this a voice-cloned dubbed audio output, or text?
Text. This tool produces translated text and subtitle files (TXT, DOCX, SRT, VTT, JSON) — no voice-cloned dubbed audio. For voice-cloned dubbing (English audio in the original speaker's voice), see specialized dubbing tools like Maestra or ElevenLabs — different product category with different pricing, ethics, and use cases. Our tool is the honest choice when you need accurate translated text or subtitles, not synthesized speech.
How much does it cost to translate a Spanish audio file?
Free for 30 minutes, then billed by minute after that. VexaScribe: 30 min free trial (no card), then $2-20/month for 200-6000 minutes. HappyScribe: 10 min free, then €15-72/month. Maestra: 10 min free, then per-minute pricing. Rev human: $1.99/min for AI + human review. For most one-off Spanish audio files (interviews, meetings, family recordings, single podcast episode), the 30-minute free trial covers you completely. For ongoing multilingual workflows, the $2/month Starter tier handles about 3-4 hours per month.
Can I translate a Spanish audio file to a language other than English?
Yes — the pipeline supports 99 source languages × 133 target languages. Translate Spanish audio to French, German, Portuguese, Italian, Japanese, Mandarin, Arabic, Hindi, Turkish, and 120+ other target languages. For non-English targets, see our general audio translator page. For English specifically (the highest-volume target), this page is the direct workflow.
How do I translate a long Spanish audio file (2+ hours)?
Same workflow, longer processing. VexaScribe accepts files up to 5 GB and 10 hours per upload. A 2-hour Spanish recording processes in about 15-25 minutes — Whisper transcribes at 4-10× real-time on our infrastructure, plus translation adds a few minutes. You'll consume 120 minutes of your plan (or the full 30-min free trial won't cover a 2-hour file — you'll need the Starter tier at 200 min/month, $2/month). For very long recordings (recorded lectures, podcast archives), the Basic tier at $5/month covers 1000 minutes.
Can I get both the original Spanish transcript and the English translation?
Yes — both are available in the same job. VexaScribe shows a bilingual side-by-side view (Spanish source on the left, English translation on the right) in the browser editor. Download options include: Spanish transcript alone (TXT/DOCX), English translation alone (TXT/DOCX), bilingual side-by-side (DOCX), timing-synced SRT subtitle files for both languages (great for adding both as caption tracks on a video), and JSON with both texts for developer workflows. Useful for verification, correcting errors, or shipping a bilingual video with both caption tracks.
