    <subfield code="a">This study investigates the acoustic properties of ejective, voiced and voiceless aspirated
stops in Georgian, a Caucasian language, and seeks to answer two questions: (i) Which
acoustic features discriminate the three stop types? and (ii) Do Georgian stops undergo
initial strengthening, and if so, is it syntagmatic or paradigmatic strengthening? Five female
speakers were recorded reading words embedded in carrier phrases and stories. Acoustic
measures include closure duration, voicing during the closure, voicing lag, relative burst
intensity, spectral moment of bursts, phonation (H1-H2) and F0. Of these, voicing lag,
voicing during the closure, mean burst frequency, H1-H2 and F0 could all be used to
discriminate stop type, but stop types did not differ in closure duration or relative burst
intensity. Georgian stops did show initial strengthening and showed only syntagmatic
enhancement, not paradigmatic enhancement. Stops showed longer closure durations,
longer voicing lags, and higher H1-H2 values in higher prosodic positions.</subfield>
