How to pronounce zstd

abbreviation contested

zee standard /ˌziː ˈstændərd/ mp3
or: zee ess tee dee /ˌziː ɛs tiː ˈdiː/

zstd is most commonly pronounced "zee standard" (/ˌziː ˈstændərd/). This is one of several readings in active use; the developer community hasn't converged on a single answer.

Zstandard compression; "Z-standard" or spelled "Z-S-T-D".

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

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