How many hours of Persian?

Learners who kept count have reported what they could follow at each stage. For an English speaker learning Persian, 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. Persian 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 Persian, expect to need fewer. How many hours you really need.

How Serval recognises Persian

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. Persian is not among the 28 languages we measured against our own recordings, so its labels rest on the model's published results. 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.

Tajik is a form of Persian written in Cyrillic. Spoken, the two are close, and the identifier reports them separately.

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

Finding Persian to listen to

Search YouTube for فارسی, Persian'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.

Persian is written in Arabic 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.

Persian belongs to the Iranian group. Serval also identifies Pashto and Tajik.

Questions

Does Serval work for Persian?

Yes. Serval identifies Persian 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. Persian has not been measured against our own recordings; the identification rests on the model's published results, and a label is only shown once two independent checks agree. You do not have to tell it you are learning Persian; it works that out by listening.

How many hours does it take to understand Persian?

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.
