# How to pronounce pi

cs-term community-consensus

pye /paɪ/
mp3

pi is most commonly pronounced "pye" (/paɪ/). This is the widely-used reading among engineers, though edge cases exist.

"pye". Greek π. 3.14159… Also Raspberry Pi.

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 pi # primary × 3 + audible "or: …" for each alternate
$ say-it --why pi # print the dict entry with source URL

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