What to check when you translate Spanish to English audio

Translate Spanish audio to English in one upload

First the Spanish recording becomes a Spanish transcript, then each segment of it is rendered in English. The timing of every segment carries over, which means you turn Spanish audio to English text and can still locate any sentence in your recording by its time.

Think of it as a Spanish to English translator, voice or video, that works on files you already have. Because the timing stays, the English version doubles as subtitles.

Spanish from Mexico, Spain and everywhere in between

Spanish sounds different in Mexico City, Buenos Aires, Bogotá and Madrid, and the vocabulary shifts too. Regional words are the first place to look when you check a transcript and its translation.

  • A car is carro in much of Latin America and coche in Spain.
  • A computer is computadora in Mexico and ordenador in Spain.
  • In Argentina and Uruguay, vos replaces tú, with its own verb forms such as vos tenés.
  • Slang like chido in Mexico or guay in Spain often has no single English match.
  • In the Caribbean, a final s often fades, so ustedes can sound close to uted.

Tú, usted and the English you

Spanish marks formal and informal address. English uses you for both, so the difference in tone disappears in translation. In an interview where a guest moves from usted to tú, that shift can matter, so mark it in brackets if your readers need to know.

He, she or you when Spanish drops the subject

Spanish often leaves out the subject, because the verb ending already carries it. Dijo que viene mañana can mean he said, she said or, formally, you said that someone is coming tomorrow. English needs a pronoun, so the translation has to pick one.

When a speaker talks about several people, compare those English lines with your recording. The sentences before usually make clear who is meant, and you can correct he or she in the editor.

Spanish words that only look English

These Spanish words resemble English ones, yet their meaning differs. Read them with care.

  • Embarazada means pregnant, and embarrassed is avergonzado.
  • Actual means current, and actualmente means currently.
  • Librería is a bookstore. A library is a biblioteca.
  • Éxito means success. An exit is a salida.
  • Constipado means having a cold.

TipRead names, numbers and these false friends in the English before you share it, and use the timestamps to find the spot in your recording.

Numbers, dates and the Spanish billón

A few Spanish number habits trip up English readers.

  • Un billón is a million million, which English calls a trillion. A billion in Spanish is mil millones.
  • Spain, Argentina and Chile write 2,5 for two and a half and 1.500 for fifteen hundred, while Mexico writes them the way the US does.
  • Dates come day first, so 3/5 is the third of May, not March 5.

Two surnames and accented names

Many Spanish speakers carry two surnames, the father's first and the mother's second, as in Gabriel García Márquez. On second mention, Spanish uses García or García Márquez, rarely Márquez alone.

Accents change names. Peña and Pena are different families, and José keeps its accent in English text. Check those letters before a quote goes out.

Ahorita and other small words

Diminutives carry tone more than size. In Mexico, ahorita can mean right now or some time later, depending on the speaker, and un cafecito is an invitation more than a small coffee. A literal English line can sound odd here, so smooth it in the editor.

Spanish clips with English captions

A Spanish clip for an English audience needs only one upload here. If you want to translate Spanish video to English captions, Single file or Unlimited exports the result as SRT or VTT, and YouTube Studio or your editor takes either file. The cues start and stop where the Spanish speaker does.

Spanish speech is quick, and English often says the same thing in fewer words, so the English lines under a Spanish speaker usually leave viewers enough time to read.

Leave official records to a certified translator

Immigration papers, court records and medical reports call for a certified human translator. Sending that person the checked Spanish transcript gives them a typed starting point.

Translation questions

How do I translate a Spanish audio file to English?

Upload the Spanish file on this page. With Single file or Unlimited, Kotosay transcribes the Spanish and translates it into English in one run, keeping every timestamp. Fix names in the editor, then download the English as TXT, DOCX or PDF, or as SRT and VTT subtitles.

Can I translate a Spanish video to English subtitles?

Yes. Upload the video here, and with Single file or Unlimited you get the English text with the timing of the Spanish speech. Export it as SRT or VTT, and each cue lands where the words are spoken. Add the file in YouTube Studio, Vimeo or your video editor as an English subtitle track.

Does it handle Latin American and Spain accents?

Yes, Spanish from Mexico, Colombia, Argentina, Spain and elsewhere all transcribes as Spanish. Regional words are worth a second look, such as carro and coche, or computadora and ordenador. Read the free first 5 minutes of your own recording to see how the accent comes through.

Can I get both the Spanish transcript and the English translation?

Yes, in two runs. Upload the file on the audio or video transcription page for the Spanish text, and here for the English. Both versions carry timestamps, so you can match lines by time. With Unlimited you download either one as TXT, DOCX, PDF, SRT or VTT.

How long does translation of a one hour recording take?

It depends on the file and how busy the servers are, so the time varies. A one hour recording needs Single file or Unlimited, which both take files up to 10 hours and include translation. On a free account the first 5 minutes of the Spanish are transcribed, so you can check the quality first.

What if the recording mixes Spanish and English?

Pick Spanish from the language list when most of the speech is Spanish, then check the English passages in the editor. Mixed speech is common in the US, so read code switching, names and brand words once the translation is ready. The timestamps show you where each of those lines sits.

Can I translate Spanish to English for free?

The translation itself comes with Single file, $4.99 once for one file, or with Unlimited, at $9.99 a month, or $119 paid once a year. On the free plan you still get the Spanish transcript, 3 files a day with the first 5 minutes of each, and you can read, edit and copy it there.

Can I translate a Spanish voice message?

Yes. Save or export the voice message from the chat app first. It is usually an OGG or OPUS file, which uploads directly. Kotosay transcribes the Spanish, and with Single file or Unlimited you translate it into English, which helps when a relative or a client sends long voice notes.

How do I check names and numbers?

Start with the English lines that carry names, street names and figures. Each one keeps the timestamp of the Spanish it came from, so you can jump to that moment in your recording and listen again. Numbers spoken quickly and surnames deserve the closest look before you share the text.

Should I use a human translator instead?

For immigration papers, court records and medical reports, yes, use a certified human translator. For interviews, family videos, classes and everyday calls, AI translation is usually enough to follow what was said. You can also give the Kotosay transcript to a translator as the source text, which saves them the typing.
