clear voice
喨 centers on a voice that is clear and distinct, carrying well without muddiness.
喨 combines 口 (mouth) with 亮, which likely contributes the sound and the idea of clarity, together suggesting a clear voice.
The mouth radical 口 beside 亮 (clear, bright) suggests a mouth producing a bright, clear sound: a clear voice.
For リョウ, imagine a clear voice ringing out like a lion's roar: lion -> リョウ, and the mouth 口 produces the clear sound.
