Just a suggestion... you'd have better thread participation if you had entitled it "Spock mind melding with a Tamarian" or something to that effect. Just "Spock" is extremely ambiguous.
Nevertheless, I think a Vulcan would be able to. The mind melding doesn't require vocal language. The concepts themselves are people, places, events, feelings, thoughts, etc... all possible to relate. It was the language construct and grammar that was the impediment to understanding them that Picard and his crew faced.
