In the word "quick," the letter "i" has a short vowel sound. A short vowel sound is typically heard when a vowel is followed by a consonant, as in "quick." This is in contrast to a long vowel sound, which is usually heard when a vowel is followed by a silent "e" or another vowel, such as in the word "bike."
The word "bat" has a short vowel sound. The "a" in "bat" is pronounced in a short and quick manner.
