How Spanish speech transcribes
Spanish is one of the strongest languages for speech recognition — Mexican, Caribbean, Andean, Rioplatense and Castilian accents all transcribe well.
What a Spanish transcript looks like
Spanish transcripts include accents and the opening ¿ and ¡ marks. Words borrowed from English (like 'marketing' or 'software') are usually kept as spoken. Fast speakers in conversation may produce longer run-on sentences, which you can split while editing. In US recordings where speakers switch between Spanish and English mid-sentence, the transcript keeps both languages as spoken.
Examples
A Madrid market-research firm transcribes a 62-minute Spanish focus-group recording to code customer language.
A reporter in Bogotá transcribes a 21-minute phone interview recorded as MP3.
Costs: 62 credits (6.2¢) and 21 credits (2.1¢), including a translated transcript if you select another language. Audio files go in the audio to text workspace.
Words that sound identical across most of the Spanish-speaking world
Spanish spelling follows pronunciation closely, but not one to one, and the gaps are exactly where a transcript can be wrong while every word is correctly spelled. Across Latin America, the Canary Islands and much of Andalusia, s, z and soft c sound the same (seseo). Almost everywhere, b and v are pronounced identically, and most speakers also merge ll and y (yeísmo). The recognizer chooses the spelling from context, and when the context is thin it can pick the wrong real word.
- tuvo / tubo
- "had" versus "tube": b and v sound the same everywhere
- casa / caza
- "house" versus "hunt": identical with seseo
- coser / cocer
- "to sew" versus "to cook": identical with seseo
- halla / haya / aya
- "finds", "there may be", "nanny": identical with yeísmo
- votar / botar
- "to vote" versus "to throw away": watch in political video
Search the transcript for any pair that matters to your topic and listen to each hit. In a cooking video, coser instead of cocer is an obvious slip. In a court hearing or a quoted interview, a wrong homophone changes what someone said.
Voseo, regional vocabulary and what stays as spoken
Argentine, Uruguayan and much Central American speech uses vos with its own verb forms: vos tenés, vos podés, decime. Check whether these come out as spoken or drift toward the tú forms (tienes, puedes). If you are quoting someone, the voseo forms should stay. Regional words are a different issue: a Mexican speaker's camión for bus, a Chilean al tiro, a Spaniard's vale. They're spelled like any other Spanish word, so spelling is rarely the problem; the risk comes later, when the text is translated and a regional meaning gets the dictionary meaning instead. Flag such words before sending the transcript to translation or to readers in another country.
Grammar you shouldn't silently correct
Some speech is regionally normal and non-standard in writing: laísmo in central Spain (la dije que viniera), dequeísmo (pienso de que), or the Caribbean habemos for hay. A transcript may record these as spoken or tidy them up; check which happened in passages you plan to quote. For quotes and research, keep the speaker's grammar. For subtitles aimed at a broad audience, a light correction is usually acceptable, but decide once and apply it consistently. Diminutives work the same way: ahorita, cafecito and chiquitito carry tone that a correction to the base word would lose.
Keeping ¿ and ¡ paired in subtitle cues
Spanish opens questions and exclamations with ¿ and ¡, and a question can begin mid-sentence: "Si llueve, ¿vamos igual?" When you split a long cue in the SRT, make sure every cue containing a closing ? also contains its ¿, or the viewer sees half a question. When you merge cues, check that no orphan ¡ is left at the start of a line. The VTT generator page explains how cues are laid out, and transcript punctuation errors covers how pauses decide where sentences end, which matters for fast speakers whose questions run into the next sentence.
Spanish and English in one sentence
US Latino speakers, Puerto Rican radio hosts and Gibraltarians may switch language mid-sentence. Look closely at the switch points: a short English phrase inside Spanish (or the reverse) can end up respelled in the other language's spelling. If a long stretch is entirely in English, decide whether you want that part translated too. Mixed-language videos explains what automatic detection does with such files and how to split them.
Costing a weekly Rioplatense podcast
A 50-minute episode saved as MP3 costs 50 credits (5¢) in transcript mode. The host wants the timestamped transcript for show notes and an English version for a co-producer, so each episode runs twice, once with Spanish selected and once with English, for 100 credits (10¢) in total. Before publishing quotes she searches for -ás and -és verb endings to confirm the voseo survived, and checks guests' surnames against the booking sheet.
The podcast transcription page covers the rest of a show-notes workflow.
Using the tool on this page
- The spoken language is detected automatically; you select the output language — the spoken language itself for an untranslated transcript, or another language for a translation. Files can be up to 2 hours long.
- Only the audio is sent for processing — the video stays on your device — and audio and text are deleted within 30 minutes of delivery (how files are protected).
- You can download a timestamped transcript, subtitles (SRT and VTT) and plain text. Every output, step and limit is explained on the video to text page.

Frequently asked questions
Which Spanish accents transcribe best?
All the major ones — Mexican, Caribbean, Andean, Rioplatense and Castilian — transcribe well. Clean audio matters far more than the accent.
Do I choose Spanish (Spain) or Spanish (Latin America) before transcribing?
Either one works. Those two options matter when translating into Spanish from another language. When the speech itself is Spanish, it is detected automatically, so for a Spanish transcript you simply select Spanish and the text comes back as recognized, without translation.
Why does my Spanish SRT show boxes instead of ñ or accented letters?
That is almost always a player or editor guessing the wrong character encoding. Open or re-save the file as UTF-8 and the letters return. Subtitles showing strange characters walks through the fix.
What if a speaker switches into Catalan, Galician or Basque?
None of those is among the 21 languages mydubly works with. Expect those passages to come out as approximate Spanish or to be garbled, so note their timestamps and ask a speaker of that language to transcribe them.
