-Frank Herbert

Grating: irritating, unpleasant, raspy, annoying, etc.
High-pitched: shrill
Plummy: describes the way English people of the upper class talk and the word is typically used with derogatory connotations
Soft-spoken: speaking with a gentle or soft voice
Strident: loud and harsh; very similar to 'grating'
Thick: if your voice is 'thick with emotion', it is generally deeper and unclearer than normal
