"a" from "a different aspect" sounds like "eɪ". What is different from the case when the native speakers pronounce it as "ə"?

Great question! Both pronunciations of "a" are correct, and can be used in any context. Most English speakers use the "ə" pronunciation most frequently, but it varies by person and by region. Additionally, when someone is speaking very slowly to emphasize something they may use the "eɪ" pronunciation of "a". However, both pronunciations are still correct.
