Over the past 6 decades, researchers in conversation analysis have repeatedly shown that everyday social activities such as inviting a friend over, interviewing police suspect, teaching class, or cross-questioning courtroom–are achieved orderly and reproducible ways. Jeffersonian transcription has been refined to both capture crystallize interactionally relevant specifics of how tasks get done....

In this work, we compare different approaches for speech segmentation, of which some are constrained and the remaining are unconstrained by phone transcript. A high accuracy speech segmentation can be obtained by approaches constrained by phone transcript such as HMM forced-alignment when exact phone transcript is known. But such approaches have to adjust with canonical phone transcript, as exa...
