Spanish is where comprehensible input as a method grew up: the Dreaming Spanish roadmap, whose landmarks this page uses, was built on Spanish learners. It also has more listening at every level than almost any other language, from slow learner channels to fast Caribbean and Rioplatense speech, so the main thing a tracker has to do is keep counting as you move between them.

How many hours of Spanish?

Learners who kept count have reported what they could follow at each stage. For an English speaker learning Spanish, roughly:

1. 50 hoursSlow, simple speech made for learners
2. 150 hoursLearner videos at normal speed
3. 300 hoursEasy native videos on familiar topics
4. 600 hoursMost everyday native speech, with effort
5. 1,000 hoursNative content feels comfortable
6. 1,500 hoursNearly everything, even fast speech

Based on the Dreaming Spanish roadmap. Spanish is in group 1 of 4 in the US Foreign Service Institute's ranking of how long languages take an English speaker to learn: one of the closest to English. So the landmarks are used as they are. If you already speak a language close to Spanish, expect to need fewer. How many hours you really need.

How Serval recognises Spanish

Serval listens to short windows of each video's sound, up to thirty seconds at a time, and a small model on your own computer names the language. No audio is kept or sent anywhere. Spanish is one of the 28 languages we measured against real recordings, and every one was labelled correctly. A label is only shown once two independent checks agree; when the audio is not clear enough, the video's time is not counted rather than guessed.

You never have to tell Serval you are learning Spanish. You only mark the languages you already speak, and everything else counts, so you can learn Spanish alongside another language and see each one's hours separately.

Finding Spanish to listen to

Search YouTube for Español, Spanish's name for itself, together with a topic you already enjoy: cooking, games, news, travel. Native speakers searching in their own language find content that searches in English miss. Early on, look for videos made for learners, with slow speech and lots of pictures, and move to native videos as they get easier; the hour landmarks above tell you roughly when.

Spanish is written in the Latin alphabet. Serval goes by sound, not subtitles, so it counts the same whether you turn captions on or not.

Close relatives

Spanish belongs to the Romance group. Serval also identifies Catalan, French, Galician, Haitian Creole, Italian, Latin, Occitan, Portuguese and Romanian.

Questions

Does Serval work for Spanish?

Yes. Serval identifies Spanish from a video's audio, on your own computer, and counts the time you spend listening to it on YouTube, Twitch, Netflix and six more sites. Spanish is one of the 28 languages it was measured on against real recordings, all labelled correctly. You do not have to tell it you are learning Spanish; it works that out by listening.

How many hours does it take to understand Spanish?

As a rough guide for an English speaker, about 300 hours of listening for easy native videos on familiar topics, and about 1,000 for native content to feel comfortable. It varies from person to person, and a language close to one you already speak goes faster.
