Free, no account needed: the first 10 minutes of each file, 3 a day. The file is deleted when it’s done and the result after 24 hours.
How accurate it is, measured
We measured it in November 2026 with 80 sentences from the public FLEURS dataset in Spanish, recorded by Latin American speakers: it got 97.4% of words right, a word error rate (WER) of 2.63%. The remaining mistakes were mostly unusual proper names and how times were written, not everyday words.
What affects the result most
More than the language, it’s how it was recorded that counts:
- Background noise, room echo and distance from the microphone.
- Several people talking at once.
- Proper names, brands and little-known acronyms: with a free account you can add them to the glossary so they’re spelt correctly.

Frequently asked questions
Does it understand Spanish from Spain and Latin America?
The measurement was made with recordings of Latin American Spanish. We don’t have figures by accent, so we won’t give you one for each: try it with your own audio, it’s free.
Does the text come with accents and punctuation?
Yes: with capital letters, accents and punctuation, so you can use it without rewriting it all.
What if Spanish and English are mixed?
Echo transcribes each file in one language. Single English words used at work usually come out fine; long stretches in another language may come out worse. If it’s mostly English, choose English.
