throat, voice
喉 centers on the throat as a physical passage and the voice that comes from it. The meanings 'throat' and 'voice' are directly connected: the throat is the organ that produces voice.
喉 combines 口 (mouth) with 侯, which likely contributes the sound. The character specifically refers to the throat, the passage behind the mouth.
The mouth 口 is the opening, and the right side 侯 looks like a passage with a lid. Picture the throat as the gateway behind the mouth where voice is formed.
For コウ, imagine a coach shouting instructions through their throat: coach -> コウ, and the voice booms from the throat.
