The plugin queries the public Free Dictionary API at runtime for exact-word pronunciation metadata and audio:

No Free Dictionary API source code or dictionary response data is bundled with
this plugin. Runtime audio is accepted only when its URL explicitly identifies
US English and uses HTTPS MP3. Individual pronunciation entries can identify
their own source page and license; those metadata remain authoritative for the
downloaded recording. For dictionary audio, the plugin appends the source page,
available artist name, and license to the Anki note's Source field.
When a selected dictionary entry identifies a Wikimedia Commons source page, the plugin queries the public Commons API for that exact page's MP3 derivative. The plugin does not bundle Wikimedia software or recordings. Each recording's source page and license metadata are supplied by the dictionary entry.
