Does SozAI transcribe Spanish?
SozAI transcribes Spanish audio and video into text across the major varieties: Castilian, Mexican, Rioplatense, Caribbean and Andean. It labels each speaker automatically, timestamps every word, restores accents and inverted punctuation, and exports to TXT, DOCX, PDF, SRT and VTT. Recordings are processed in EU data centers and encrypted at rest, and every account gets 30 minutes a month without a card.
Español, written the way it is actually written.

Workflow
Record straight into the app, upload a file up to 500 MB, or paste a YouTube link. SozAI reads m4a, mp3, wav, aac, mp4 and mov.
Choose Spanish when you already know the variety, or leave detection on. Recordings that switch between Spanish and English stay in a single transcript rather than being split.
The transcript arrives with speaker labels and word timestamps. Search it, ask it questions, generate a summary in Spanish, or export SRT and VTT subtitles.
Field notes
A Buenos Aires interview, a Havana phone call and a Madrid boardroom share a spelling system and almost nothing else in the audio. Rioplatense turns "ll" and "y" into a sh-sound, Caribbean speech drops or aspirates the final "s" so plurals disappear acoustically, and Andean Spanish keeps vowels that other varieties reduce. Transcription quality is set by variety coverage far more than by any single accuracy figure.
Spanish has one of the highest syllable rates of any widely spoken language, and words run into each other without the pauses an English speaker would leave. "No sé" and "nose" are the same sound. The transcript has to be reconstructed from grammar, not just from the acoustic signal, which is why context-aware models pull ahead on fast conversational audio.
Argentina and much of Central America use "vos" with its own verb forms; Spain separates "vosotros" from "ustedes" while Latin America does not. Getting the pronoun wrong changes who is being addressed and how formally. SozAI writes back the form that was spoken instead of normalising everything to a textbook standard.
US-based recordings routinely switch mid-sentence — a sales call that runs in Spanish and names products in English, a clinic visit that mixes both. Splitting the file into two languages destroys the thread. The transcript keeps each fragment in its own language, in the order it was spoken.

Answers
Short answers you can quote. Longer ones live in the sections above.
SozAI handles Castilian (Spain), Mexican, Rioplatense (Argentina and Uruguay), Caribbean and Andean Spanish. You can pick the variety or let automatic detection choose from the first seconds of speech. Accuracy is highest on clear studio-quality audio and drops on fast Caribbean speech recorded over a phone line, so microphone quality pays for itself.
Yes. The transcript comes back with the full orthography: acute accents, ñ, diaeresis, and the opening ¿ and ¡ that Spanish requires. This matters more than it sounds — "esta" and "está" are different words, and a transcript that drops accents is not quotable in a document or a subtitle file.
Yes. Speaker diarization runs on the audio rather than the language, so it separates voices in Spanish exactly as it does in English. Each turn gets a label and a timestamp, which is what makes an interview or a focus group usable as a citable source rather than an undifferentiated block of text.
Code-switched recordings stay in one transcript. SozAI writes the Spanish in Spanish and the English in English, in the order they were spoken, instead of forcing everything into one language. This is the normal case for US healthcare, sales and education recordings, and splitting the file is almost never what you want.
Every account gets 30 minutes of transcription per month at no cost and without a card. Beyond that SozAI is a flat monthly subscription with a shared pool of minutes, and the price does not depend on the language — Spanish costs the same as English. Current plans are listed on the pricing page.
