Transcribe Spanish meetings and audio
Upload a Spanish recording up to 2 GB - a meeting, a sales call, an interview - and IronMemo returns speaker-labeled text with clickable timestamps. Spanish is routed to the speech model that wins our benchmark for Spanish, and English words spoken mid-sentence stay English instead of being flattened into a single language.

What changes across the Spanish-speaking world
Six varieties, one language setting. These are not options you choose - they are what a speech model actually has to cope with.
Peninsular Spanish
castellanoCastilian keeps the c and z sound distinct from s, and uses vosotros where Latin America uses ustedes - a model tuned mostly on American Spanish gets both wrong.
Mexican Spanish
español mexicanoThe largest Spanish-speaking population, and the one that drops English business vocabulary into Spanish sentences most often - the switch is where generic transcription loses words.
Colombian Spanish
español colombianoTwo systems in one country: conservative Andean speech, often called the clearest Spanish there is, and coastal costeño that softens or drops the final s.
Rioplatense Spanish
castellano rioplatenseVos replaces tú and moves the stress inside the verb, and ll and y come out as a sh sound - familiar words arrive in an unfamiliar shape.
Chilean Spanish
español chilenoFast, with the final s aspirated away and consonants dropped at the ends of words - the combination that trips a model trained mostly on careful speech.
US Spanish
español estadounidenseWhere Spanish and English mix most densely - whole English clauses inside Spanish grammar, which single-language transcription flattens into one.
IronMemo treats Spanish as one language and routes it to the speech model that wins our benchmark for Spanish. The six varieties above - Peninsular, Mexican, Colombian, Rioplatense, Chilean and US Spanish - are not separate settings you pick; they describe what genuinely varies across the Spanish-speaking world, and why a single global model is not automatically good at all of it. Updated July 2026.
One language per meeting, or both at once
What notetakers publish about their own handling of mixed Spanish and English - and what happens on IronMemo instead.
How most notetakers handle a bilingual meeting
- Read.ai states that meetings where several languages are spoken are not fully supported and may produce inconsistent results.
- Circleback detects the predominantly-spoken language and transcribes the whole meeting in that one language.
- Krisp asks you to select a language before the call, and the transcript comes back in that language.
- Fireflies does detect switches at word level, but its Multi-Language Mode is limited to the Business and Enterprise plans.
How IronMemo handles it
- The language is detected first, then Spanish is routed to the speech model that wins our benchmark for Spanish - not to a global default.
- An English sentence inside a Spanish meeting stays English on the same transcript, with the speaker label intact.
- Timestamps stay continuous across the switch, so every summary line still points at the moment in the recording it came from.
- There is nothing to configure before the call: you do not pick a language, and you do not lose the meeting when someone switches.
To be fair: if your meetings run entirely in Spanish on clean audio, most of these tools will do a decent job, and Sonix is refreshingly honest that its own multi-language handling works best when the switch happens between speakers rather than mid-sentence. The gap opens exactly where mid-sentence switching is normal - which is most teams working across Spanish and English.
How Spanish transcription works
Three steps. You upload, we route, you get text you can check against the audio.
Upload the recording
Drag a Spanish audio or video file into the browser - MP3, M4A, WAV, OGG, OPUS, MP4 or WebM, up to 2 GB. No bot has to join the call: an old phone recording and a two-hour meeting go through the same door.
Spanish gets its own model
The language is detected, then the recording goes to the speech model that won our benchmark for Spanish - picked on Spanish audio, not on an average dominated by English. English words inside Spanish sentences do not force a restart.
A transcript you can audit
In minutes you get Spanish text with speaker labels and clickable timestamps, plus a summary whose every line points back at the exact moment in the recording it came from.
Five conditions that break Spanish transcription
Not the language list - the room. This is what actually costs you accuracy in a Spanish meeting.
| In a real Spanish meeting | Why generic transcription struggles |
|---|---|
| Two or three people talking at once | Published accuracy numbers describe clean audio: Sonix quotes 85-99% depending on audio quality for all of its languages at once. |
| Fast speech with the words running together | Spanish is delivered at a high syllable rate and word boundaries blur, so a model tuned elsewhere splits words in the wrong places. |
| Dropped final s and softened consonants | Caribbean, Chilean and Andalusian speech remove sounds a model trained mainly on careful speech expects to hear. |
| English words inside Spanish sentences | Read.ai says multi-language meetings are not fully supported; Circleback picks the predominant language; Krisp asks you to choose one up front. |
| Long recordings nobody was watching | Free tiers meter minutes and file caps bite - Notta free allows 120 minutes a month and 1 GB per audio file; Sonix caps files at 4 GB. |

Who transcribes Spanish with IronMemo
Teams split across Spain and Latin America, bilingual sales calls, and long-form Spanish interviews - all on the same pipeline.
Teams split across Spain and Latin America
Weekly stand-ups in Spanish, quarterly reviews in English, one searchable record - and speaker labels that survive both halves of the week.
Bilingual Spanish-English calls
Discovery calls, hiring interviews, partner syncs: the transcript keeps both languages side by side instead of flattening the meeting into whichever one was louder.
Long Spanish interviews and research
Two-hour source interviews, focus groups and lectures - the full transcript with speakers and timestamps, ready for coding or quoting.
Three numbers behind Spanish on IronMemo
What the routing is built on, and what you can actually upload.
95
speech models benchmarked
Champions come from a continuously updated research base of 95 speech models and 120+ independent sources - and Spanish is scored on Spanish audio.
2 GB
per file
A two-hour Spanish meeting fits even as uncompressed WAV, and the free plan does not meter transcription minutes.
ES + EN
on the same line
A mid-sentence switch into English does not break the transcript, the speaker labels, or the timestamps.
