for me, thought are really abstract and it takes a bit to translate them into words. and even though i’ve spoken english for around 8 years, i can still notice that i take way longer to write things in english than my first language. though i guess that might be related to me basically only listening and typing in english and not actually talking out loud enough. in my first language, portuguese, it’s the same situation, it just takes less time to translate the thoughts into words
