The whole internet not the translated part of it
Most of the technical, medical and business video on the web exists only in English, and the Spanish version of it, when one exists, is late and partial. Translating on the viewer's side removes that dependency entirely. You are no longer waiting for anyone to decide your language is worth the localisation budget.

A real voice not a robot reading
The Spanish track uses natural speech synthesis with pacing that follows the speaker rather than a flat monotone that finishes early and leaves gaps. On a long lecture that difference is the whole experience.
Install on ChromeSubtitles to read dubbing to listen
Reading Spanish subtitles works when you can look at the screen. When you cannot, the spoken track takes over and the video becomes something you can listen to while doing something else. Both modes run off the same session.

English to Spanish is the biggest gap online
Spanish is one of the most spoken languages on earth and one of the worst served by online video, because the material people need is produced in English and localised slowly if at all. University lectures, developer conferences, product documentation walkthroughs and medical training sit behind an English-only wall for audiences who are perfectly capable of the content and just not the language.
The practical answer has never been to translate the internet. It is to translate the one video you are watching, at the moment you watch it, which is a much smaller problem.
The reverse direction is covered on the Spanish to English page, and for conversations where both sides want their own language there is two-way translation.
Questions about this language pair
Which Spanish does the voice track use?
A neutral Latin American Spanish by default, which is the widest fit across regions. The written subtitles avoid regionalisms for the same reason.
Does it work on course platforms and webinars?
Yes. Any browser tab that plays audio works, which covers most course platforms, webinar tools and conference replays.
Can I read Spanish subtitles and still hear the English?
Yes. Use subtitles only and leave the source volume up, which is the usual setup for people improving their English.
Is there a delay?
Around a second, varying with connection quality and speech density.
Does it work on live meetings?
Yes, on Zoom, Google Meet, Microsoft Teams and Webex.
Do I have to pay to try it?
No. The free tier includes a monthly allowance of translation minutes.
