英語語音學二 13. Dorsal Consonants (2021 updated)

Whole-channel inclusion: NTU OpenCourseWare is an honest teaching channel (title sample + 3 transcripts read: All samples lack transcripts but descriptions and timestamped outlines confirm they are full-length structured university lectures consistent with the channel's OCW teaching format.); this title passed a strict title check (sonnet) after a labelling pass.
