Gould's in-game voiceover for Gex was highly praised. Gilde stated that it never became obnoxious due to the wide range of different one-liners present in-game. Storm called Gex's voice "the first time a game character has ever been given voice and personality that has actually turned out to be cool" and stated that the many written phrases suited his character. Skid felt that the vocals added to the game's enjoyability, while Rox wrote that they were mostly "hilarious... when you can hear them over the music and sound effects." In reviewing the PC version for PC Powerplay, David Wildgoose wrote that Gex's "American slacker voice" would be viewed by players as either "cool or grating", although he admitted to personally not minding it. Lee praised the game's music, calling it "high quality."
