Field notes
The page explains its processing chain: it starts with the Carnegie Mellon Pronouncing Dictionary, converts entries to IPA with primary stress, then syllabifies them using the Maximum Onset Principle. It reports more than 141,000 word maps, while separately describing an extension database of more than 120,000 words; the web IME demo searches the 3,000 most frequent. The two browser extensions are described as running locally, without accounts, trackers or uploads.
