Mine are very different. Monty is so loud, he can be heard outside the house for some distance. He doesn't talk, he just does a lot of squawking. Most of it is loud enough to be uncomfortable for my ears.
Mitzi talks and makes whistles and chirrups but nothing that is loud enough to be uncomfortable for my ears.
Somewhere in another universe, dear brother, you got saved.
Sheeba is very considerate with her screaming/loudness. She will just talk away and be a nice little birdy, until you put her in her cage while I have to clean house or work, then she has a blood curdling screechy noise that will give you a headache!
