Background: There were aspirated stops at three places of articulation: labial, coronal, and velar /pʰ tʰ kʰ/. Earlier Greek, represented by Mycenaean Greek, likely had a labialized velar aspirated stop /kʷʰ/, which later became labial, coronal, or velar depending on dialect and phonetic environment.
Question: What is the representation for the three places of articulation?
Answer:<extra_id_0>.
<extra_id_0> /pʰ tʰ kʰ/<extra_id_1>
