Un modello per l’annotazione di fatti prosodici nelle trascrizioni forensi

Over the last forty years, the number of wiretappings and forensic transcriptions has considerably increased. Even though forensic experts have developed proper, yet different, protocols to transcribe the segmental units of wiretapped speech, the prosodic features of recorded conversations still lack of a model of forensic annotation. The goal of our study is placed in this technical vacuum: after describing prosody, its features, textual functions and the relations among prosodic phenomena and the different levels of grammar (e.g. syntax, semantics, ecc.), the article deepens the scientific value of forensic transcripts and the advantages of transcribing supra-segmentals. For this purpose, we propose an innovative prosodic annotation model that takes into account the tonal units and the prominence of wiretapped conversations in order to avoid the so-called disputed utterances and to establish some kind of homogeneity among forensic practises.
