Cats typically don't speak human language because they lack the grammatical structure and semantic understanding of human language. However, some cats may make sounds similar to human voices, possibly because they have learned and imitated human speech patterns through interaction with humans.

For example, if cats frequently hear their owners speak, they may try to imitate those sounds, thus producing vocalizations that resemble human speech. Furthermore, cats have a very rich vocal repertoire; they can produce approximately 100 different sounds, and some cats possess strong learning abilities, enriching their vocal expression through imitation.
