How to pronounce Dirichlet (and the alternate readings)

Q: How do you pronounce Dirichlet?

Dirichlet is pronounced "deer ick LAY" (/ˌdɪərɪˈkleɪ/). Named after German mathematician Peter Gustav Lejeune Dirichlet — ubiquitous in ML via the Dirichlet distribution and Latent Dirichlet Allocation (LDA, Blei/Ng/Jordan 2003). The surname LOOKS French (from 'Richelette' in French-speaking Belgium) but he lived in German lands, so two camps exist: the German-style deer-ick-LAY (hard 'k', /kleɪ/) vs the French-style deer-ish-LAY (soft 'sh', /ʃleɪ/). Final stress on -LAY; the 't' is silent in both common readings (though a minority, citing Calabi, insist on a hard final 't'). Wikipedia's own talk page never resolved it — a contributor jokes that saying it 'correctly' makes you sound wrong to most mathematicians. Wikipedia documents the English IPA as the hard-k /ˌdɪərɪˈkleɪ/; many ML practitioners say deer-ish-LAY. Source: Wikipedia Talk § Pronunciation (Peter Gustav Lejeune Dirichlet).

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
