quoting Travis B.:

I assumed that all /s/s were really /s̺/, that the /ʃ/ was really /tʃ/, that the /ʒ/ was really /dʒ/, and that the /ɾ/ was really /r/.

I also assumed that the /ð/ was its own phoneme.

(One question - why is it mostly voiced obstruents that are being ejectified here, not voiceless ones?)
