The situation is that I asked a question with a short film here. The respondents commented according to the film with the sentences as follows.
1."The speaker (in the film) may not use a flap /t/ here because she's enunciating carefully, because..."
- "I think the reason that the fifth speaker (in the film) doesn't use the flap t is that she's speaking slowly and emphatically."
My question is why they use the present continuous tense to describe the speaker's action in the film. After checking when to use the present continuous tense, I found one of the rules at British Council Learning English, saying when to summarize a book, film or play. Is that the reason?
But, I also found the same rule to use the present simple tense at British Council Learning English as well. Therefore, can the sentences from the respondents above be changed to use the present simple? If they can, are there any differences between using the present simple and continuous?
