Students at Yale Law School have compiled and published what they call the Pronouncing Dictionary of the Supreme Court of the United States.
Although the United States is famously a nation of immigrants, Americans often struggle with the pronunciation of foreign words and names. Mispronunciation of even common foreign words is ubiquitous (Eye-rack and Eye-ran spring to mind). Foreign names in legal matters present a particular challenge for legal professionals. The purpose of the Pronouncing Dictionary of United States Supreme Court cases, … is to help conscientious lawyers, judges, teachers, students, and journalists correctly pronounce often-perplexing case names.
You can either view the names on the website or download the full PDF (15 GREEN BAG 2D 433)
There is also an explanation of the phonetic symbols and transcription practice used pronunciation notes (PDF)
The chart notes the Americanized pronunciation of the difficult name, Bryan Garner’s, and the International Phonetics Association American and Native Speaker Pronunciation. This might be a great asset when having to cite these cases in court or for a class presentation.
