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. Pronounce is a community-maintained dictionary — every entry tagged with a confidence level and (where possible) a citable source.

Hear it from the command line

$ say-it CISO # primary × 3 + audible "or: …" for each alternate

$ say-it --alt CISO # focus on the first alternate

$ say-it --all CISO # primary AND every alternate, each repeated

$ say-it --solo CISO # primary only, no "or: …" tail

$ say-it --why CISO # print the dict entry with source URL
