## PROFESSOR GRAYMATTER — Voice Description (498 characters) ``` Male, age 60, deep baritone with rich chest resonance. Strong thick modern German accent on every word — "w" softens to "v," "th" becomes "z," hard consonants, clipped vowels, rolled r's, final d hardens to t. Booming theatrical projection at stage volume, diaphragmatic, never throat-bound. Wide pitch range above a deep baseline. Eccentric, manic, shouting with delight every line. Doc Brown: unhinged enthusiasm, loud declarations, can't contain himself. Never conversational, never British, never calm. ```
