לָ֭רֹכֵב בִּשְׁמֵ֣י שְׁמֵי־קֶ֑דֶם הֵ֥ן יִתֵּ֥ן בְּ֝קוֹלוֹ ק֣וֹל עֹֽז׃
[Célébrez] Celui qui chevauche les cieux antiques; voici qu’il fait retentir sa voix, une voix formidable.
Sefer HaMiddot
3. One can recognize in a man's voice, whether he is humble or arrogant (t.n. The commentators do not provide any citations here, and there are many verses to bring, so I will present just two, a hint from Psalms 68:34 -- he makes a voice of strength, and see Shemos 32:18 where Moses discerns the type of calling. Also see Likutay Moharan at the end of Torah 30).
