Spectral Tilt

Spectral tilt refers to vocal effort and intensity. According to Andrew Huberman, it denotes the way individuals emphasize and enunciate words and syllables in speech. Cannabis users tend to exhibit reduced spectral tilt, meaning their vocal effort and intensity in speech is diminished. This results in less enunciation and accenting of particular words and syllables compared to non-users, who would typically have more vocal variation and clear articulation when speaking 1.
