A lightweight **word → IPA** pronunciation lexicon for European Portuguese,
extracted from [Infopédia](https://www.infopedia.pt/) (Porto Editora). One row

modelling, and TTS/ASR lexicon building.

> **Complete crawl.** Derived from a graph crawl of Infopédia that ran to
> convergence (frontier → 0), covering the dictionary's reachable component.
