True Speech · v0.4.0 · Sandbox
A scratch space for tinkering with truespeech. The notebook below is yours to play in; results stack as cells you can scroll back through. The database is read-only, but you can freely modify the lexicon — just reload the page to restore the seed lexicon. Looking to learn the language? Start with the tutorial. Need the full grammar? See the reference. Want to peek at the implementation? The runtime source is on GitHub.
The corpus is NorthStar Goods, a fictional mid-size US retailer — ~200 rows of order data spanning Jan 2025 through Apr 2026, with two product tiers (consumer / enterprise) across four regions. The lexicon is preloaded with a handful of entries from their operating life — known data-quality windows, a regional outage, a couple of metric-definition changes.
