Syntactic actants

Actant 1: whose voice it is
(a) Genitive
(b) Possessive
Голос Марии был звонкий и весёлый. Maria's voice was clear and cheerful.
Мне нравится его мягкий голос. I like his gentle voice.
NB When the word голос functions as a subject and does not have a descriptive modifier, the construction голос у + Genitive is often preferred to (a) and (b), above:
Голос у Марии был звонкий и весёлый. Maria's voice was clear and cheerful.
