git clone https://github.com/anzy-renlab-ai/pronounce.git
cd pronounce && ./install.sh
say-it kubectl

That's it. Now try say-it GIF, say-it nginx, say-it Pydantic, say-it --why JSON, or say-it quiz for a 10-question challenge. Linux users: install espeak-ng (sudo apt install espeak-ng) and the CLI just works. Windows: same CLI under WSL or git-bash + PowerShell. Or skip install and use the browser at pronounce.renlab.ai.
โญ If
say-it kubectlsaves you one cringey standup moment โ star the repo. It nudges more devs to contribute their favorite mispronounced project name.
What you're actually getting
- 1702 entries, every one sourced. Confidence-tagged (
creator-clarified/community-consensus/contested) with a citable URL where one exists. Wilhite said GIF is "jif" at the 2013 Webby Awards. Crockford says JSON is "JAY-son" (RailsConf 2009). RFC 7519 says JWT is "jot". The dictionary cites them. - Multi-reading audio. For words where the debate is real โ GIF, SQL, GUI, char, regex โ the CLI chains the alternates after the primary with a spoken "or:" so you hear the debate without staring at the terminal.
--soloskips the tail once you've internalized it. - Zero deps. ~250 lines of Bash. No npm, no sudo, no surprises. Wraps the
sayengine that's already on your Mac. Ships a Claude Code skill and an MCP server so your AI answers "how do you pronounce X?" with audio, not a phonetic guess.

Why not just Google?
Because Google gives you 47 Reddit arguments and a YouTube clip you have to unmute. IPA gives you /หkuหb kษnหtroสl/ โ a reference, not a teacher.
You don't need a phonetic transcription. You need to hear the word. Twice. Maybe three times. Done.
say-it ships a community-maintained dictionary of how engineers actually say the names that trip everyone up โ and feeds the intended respelling to your OS's text-to-speech engine, so kubectl comes out as koob-control, not whatever your computer guessed from the letters.
Famous moments
Some pronunciations aren't opinions โ the creators settled them. The dictionary cites every one:
| Word | Reading | Source |
|---|---|---|
GIF | "jif" (creator says so) | Steve Wilhite, Webby Awards 2013 |
JSON | "jay-son" | Douglas Crockford, RailsConf 2009 |
GNU | "g-noo" (hard G, one syllable) | GNU Project official |
Linux | "LIN-ux" (short i, schwa) | Linus Torvalds himself |
LaTeX | "lay-tek" (or "lah-tek") | Leslie Lamport, official |
Django | "JANG-go" (silent D) | Django FAQ |
Vue | "view" (one syllable) | Evan You, Vue docs |
Vite | "veet" (French for quick) | Vite docs |
Knative | "KAY-native" (the K is voiced) | Knative docs |
etcd | "et-cee-dee" (et-cetera-distributed) | etcd FAQ |
Every dictionary entry includes a source_url. Run say-it --why <word> to see it.
Install (macOS)
brew install anzy-renlab-ai/tap/say-it # Homebrew
Or the "Try it in 30 seconds" block above. ./install.sh drops:
- the CLI at
~/.local/bin/say-it, - the pronunciation dictionary at
~/.local/share/say-it/pronunciations.tsv, - if you use Claude Code, a
pronounce-wordskill at~/.claude/skills/pronounce-word/so any "how do you say X?" prompt to your AI gets answered with audio instead of IPA, - the same skill into
~/.agents/skills/(Codex CLI) and~/.kiro/skills/(Kiro) when those dirs exist โ it's the cross-tool Agent Skills standard.
Make sure ~/.local/bin is on your $PATH. Linux also works โ install espeak-ng (sudo apt install espeak-ng / brew install espeak-ng). Windows: WSL or git-bash + PowerShell. Or skip install entirely with the browser version at pronounce.renlab.ai.
Usage
say-it kubectl # primary ร 3, then "or: <alt>" for each alternate
say-it --solo kubectl # primary only โ silence the "or:" tail
say-it --alt GIF # focus on the first alternate
say-it --alt 2 GUI # focus on the Nth alternate (1-indexed)
say-it --all SQL # primary AND every alternate, each repeated
say-it --no-dict kubectl # bypass the dictionary entirely
say-it --why JSON # show IPA, source URL, category, confidence
say-it list # every word in the dictionary
say-it search redis # grep the dictionary (case-insensitive)
say-it -n 5 Pydantic # 5 repetitions instead of 3
say-it -r 110 Knative # slower (110 wpm; default is 130)
say-it -o /tmp/word.aiff Postgres # save to file instead of playing
say-it --list # all macOS voices
The default voice is Samantha (General American). Pass -v <voice> for any other macOS voice โ but the dictionary is GenAm-only, by design.
Claude Code integration
You: kubectl ๆไน่ฏป๏ผ
Claude: ๐ (plays "koob-control" three times)
/หkuหb kษnหtroสl/ โ "KOOB-control". Kelsey Hightower says it
this way (KubeCon talk). "Cube-cuddle" is an alternate โ
try `say-it --alt kubectl` to hear it.
Once installed, the pronounce-word skill auto-triggers on:
X ๆไน่ฏป/X ๆไนๅ้ณ/่ฏปไธไธ Xhow do you pronounce X/pronounce X/how do you say X
Your AI replies with sound, not just a phonetic guess. Skill file: skills/pronounce-word/SKILL.md.
Not on Claude? Same skill drops into Codex CLI (codex plugin marketplace add anzy-renlab-ai/pronounce) and Kiro (~/.kiro/skills/), and the MCP server covers Claude Desktop, Cursor, Continue, Zed, Cline & friends โ full matrix in integrations/.

How the dictionary works
data/pronunciations.tsv is the single source of truth โ tab-separated, 1702 entries, covering:
- Cloud / DevOps:
kubectl,nginx,Kubernetes,helm,Istio,Envoy,Prometheus,Grafana,Terraform,Argo,Knative,etcd,containerd,runc,Podman, ... - Languages / Frameworks:
Django,Vue,Vite,Pydantic,Bun,Deno,Hugo,Hono,Caddy,Svelte,Astro,Pinia, ... - Databases:
PostgreSQL,Postgres,SQLite,MySQL,MongoDB,Cassandra,Redis,Ceph,ScyllaDB,ClickHouse,DuckDB, ... - CS jargon / acronyms:
GIF,JSON,SQL,GUI,GNU,char,regex,sudo,tmux,chmod,WYSIWYG,ASCII,enum,NaN,SaaS,PaaS, ... - Distros / tools:
Linux,Debian,Ubuntu,Arch,Nix,LaTeX,TeX,emacs,zsh, ...
Each entry has 10 columns: word | ipa | phon_us | alt_ipa | alt_phon_us | source_url | source_label | category | confidence | notes. The phon_us column is Apple's Speech Synthesis phoneme set, injected into say via [[inpt PHON]]โฆ[[inpt TEXT]]. This is what gives the intended reading rather than whatever the TTS would have inferred from the letters.
Local override: drop a ~/.config/say-it/pronunciations.local.tsv and it takes precedence.

Contributing
Two things we want most:
- Pronunciation entries. Open a PR adding a row to
data/pronunciations.tsv. Required columns:word,ipa,phon_us. Highly preferred:source_url(creator interview, conf talk, official FAQ โ anything verifiable). Contested readings are welcome; put the rival inalt_*columns and we'll wire--altthrough. - Non-Mac backends. Windows and Linux are top priority. See
DESIGN.mdยงBackends.
Keep it tiny. Keep it dep-free where possible. Keep the defaults opinionated (3 reps, GenAm, Samantha voice).
โญ Support โ start with a star
The dictionary is free and MIT. The single highest-leverage thing you can do is star the repo โ it's the signal that pulls in more contributors, more PRs, more creator-clarified entries.
- โญ Star on GitHub โ โ one click, no signup, biggest effect.
Optional, if it's saved you real standup pain:
- โ Coffee on Ko-fi โ pays for one new entry per cup.
- ๐ Sponsor on GitHub โ recurring tier (pending Sponsors approval).
Dollars cover hosting (Vercel/Cloudflare/Open VSX), domain renewals, MiniMax narration credits for promo videos, and time to track down creator citations for new entries.
