Speech transcription tool for efficient speech transcription

摘要

A transcription tool 115 includes a graphical user interface 209 that displays the waveform of an input audio signal to a user. The user may define speaker turn segments using the displayed waveform. The graphical user interface further displays a transcription section 302 that includes a textual representation of speech that was transcribed by the user and a graphical representation of annotation information 314 relating to the transcribed text. The user may enter the annotation information on-the-fly while transcribing the text using predefined keyboard shortcut commands or other mechanisms. The graphical user interface may further display a structured representation section 303 that may present the transcribed text as a hierarchical tree structure.
