When I was studying English pronunciation and Phonetics BBC helped me a lot!

In Phonology, many YouTube channels helped me to understand the features of English, how native speakers speak English, and to realize the differences b/w my L1 and English.
In Listening, I faced a problem which is "I cannot focus/continue with long dialogs". However, ESL podcast helped me more than what can you think:
Improved my vocabulary, pronunciation and listening skill!
The best thing ever about ESL podcasts that you can subscribe the channel on your phone and the episode will be downloaded directly to keep up with new ones~~~~
