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 CORS # primary × 3 + audible "or: …" for each alternate
$ say-it --alt CORS # focus on the first alternate
$ say-it --all CORS # primary AND every alternate, each repeated
$ say-it --solo CORS # primary only, no "or: …" tail
$ say-it --why CORS # print the dict entry with source URL

Install the CLI: git clone https://github.com/anzy-renlab-ai/pronounce.git && cd pronounce && ./install.sh
