Aldous Huxley was a respected author of science-fiction and other works. He was British, so his name follows the conventions of British pronunciation instead of American pronunciation. His first name, "Aldous," may derive from or be related to the name "Aldo," and is pronounced "All-Dus," with the emphasis on the first syllable. The second syllable is not stretched to "Doos," but is short, and could be phonetically written "Das" or "Dos," depending on inflection.
His family name, "Huxley," is pronounced "Huks-Lee," again with the emphasis on the first syllable. The "X" in his name takes the "KS" sound, and follows the vowel U to create "Huks," not as in "Hooks," but as in "Trucks." The second syllable, "Ley," is not pronounced "Lay," as it may seem on first glance, but as "Lee," as in "Tree."
Together, his name is pronounced "All-Dus Huks-Lee," with emphasis on both first syllables and without any syllable being excessively drawn out. One link below will pronounce it through your computer speakers.
