Could you please improve my sentences?

When English people speak naturally , they don’t pronounce a word, stop, then say the next word in the sentence, this is because of connected speech. In Arabic, speakers tend to separate between two words, which one ends with a vowel sound and the second begins with a vowel by using the intrusive glottal stop. This is because it is difficult for them to connect between vowel sounds as the air stops quickly in the throat. For example, the speaker said /hi: ?ɪz / instead of /hi:z/. She said /hi: / stopped, and then said /ɪz/. However, this does not with English spoken, “he” as it ends with a vowel, and “is” as it starts with a vowel should be connected together. Therefore in order to connect between them, there is a need of use a glottal stop. How can the speaker use it? She first needs to stop the airflow in her throat, then try to hold her breathe with her throat muscles, and then release the air by relaxing the throat muscles.
