English Talking of Speak

My mother helped monetarily, so I continue to use the app called Speak, to speak English at all. But I'm often depressed when AI have pointed out my imperfect English I've spoken. I may be premature to speak perfect English despite achieving 840 TOEIC score. Anyway, It's no choice, except I speak English in Speak many times and I become used to speak English. I spoke about my having gone to Thailand, about having collected the illustration of Hakkenshi and so on, in Speak Actually, I want to talk with foreign travellers and introduce them Japanese culture such as Hakkenden. But it may be early because my speaking English is imperfect.
