Heads-up: This question is purely opinion-based, I am therefore asking it on Meta. Please let me know if it is off-topic here.
I am a non-native speaker of English and have been speaking English for quite a long time. I have noticed that while speaking English, my tongue, jaws, lips and mouth get tired while speaking English. When speaking in my native language, I can speak for how long I want and my speech organs do not get tired. (I'd rather not say what my native language is.) I would like to know if other non-native speakers experience the same thing. I assume it is because my speech organs are not used to producing the sounds/ patterns of sounds of English.
Do other non-native speakers have the same experience with speaking English?
(I have also asked this question on Linguistics Stack Exchange here, but that is about other languages.)
