AB - This study investigates the prosodic realization of pragmatic markers in spontaneous English vlog speech, focusing on interjections, discourse markers, and hybrid forms. A total of 250 tokens (86 items) extracted from English-language YouTube vlogs were analyzed using acoustic–phonetic measures of speech rate, pitch, intensity, and pause behavior. The results show that speech rate is the most robust distinguishing cue: interjections are produced more slowly and occur more frequently with pauses than discourse markers and hybrid forms. Pitch and intensity do not reliably differentiate categories in absolute terms, although interjections exhibit localized pitch elevation and increased loudness relative to surrounding speech. By moving beyond predominantly impressionistic classifications, this study demonstrates the feasibility of quantitatively distinguishing pragmatic marker types and highlights temporal organization as central to pragmatic prosody, with implications for automatic discourse analysis and data-driven speech-based learning systems.
