Hindi has an enormous amount of native video, from films to news, and the spoken language is very close to Urdu, so the two grow your listening together. English words are common in everyday speech, which helps beginners and is normal in native content.

How many hours of Hindi?

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

1. 75 hoursSlow, simple speech made for learners
2. 225 hoursLearner videos at normal speed
3. 450 hoursEasy native videos on familiar topics
4. 900 hoursMost everyday native speech, with effort
5. 1,500 hoursNative content feels comfortable
6. 2,250 hoursNearly everything, even fast speech

Based on the Dreaming Spanish roadmap. Hindi is in group 3 of 4 in the US Foreign Service Institute's ranking of how long languages take an English speaker to learn: well away from English. So the landmarks are raised by half. If you already speak a language close to Hindi, expect to need fewer. How many hours you really need.

How Serval recognises Hindi

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. Hindi 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.

Spoken Hindi and Urdu are very close. Both count as input unless you have marked one of them as a language you speak, so a Bollywood film counts either way.

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

Finding Hindi to listen to

Search YouTube for हिन्दी, Hindi'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.

Hindi is written in Devanagari script, which you do not need to read to start listening. Serval goes by sound, not subtitles, so it counts the same whether you turn captions on or not.

Close relatives

Hindi belongs to the Indo-Aryan group. Serval also identifies Assamese, Bengali, Gujarati, Marathi, Nepali, Punjabi, Sanskrit, Sindhi, Sinhala and Urdu.

Questions

Does Serval work for Hindi?

Yes. Serval identifies Hindi 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. Hindi 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 Hindi; it works that out by listening.

How many hours does it take to understand Hindi?

As a rough guide for an English speaker, about 450 hours of listening for easy native videos on familiar topics, and about 1,500 for native content to feel comfortable. It varies from person to person, and a language close to one you already speak goes faster.
