- What it is
- The README of PocketSphinx, the lightweight recognizer in the CMU Sphinx family. Its authors section explains that the code descends from older Carnegie Mellon systems released under a BSD-like license.
- How much weight it carries
- Official project repository, so it is authoritative for the license history. It does not give current accuracy or language figures, so the guide does not use it for those.
