Using Speech Technology to Improve Transcriptions: An Exploratory Study

摘要

Modern speech technology is finding many new application areas within Defence. Transcription is one area where speech recognition technology is starting to replace manual methods. This adoption of speech technology is motivated by its potential to save transcribers significant amounts of time and physical effort. As part of their evaluation of military organisations, analysts from the Theatre Operational Analysis (TOA) Group within the Command and Control Division (C2D) transcribe recorded information that has been captured during interviews with Defence personnel. An exploratory study was conducted within TOA Group to look at ways of using commercial speech technology to assist in the transcribing of recorded interview material. This report describes the method used and the results obtained from that study. The report also compares traditional manual transcription approaches with newer approaches that make use of speech recognition technology. The qualitative and quantitative results obtained from this study will help to benchmark the utility of current commercial speech technology used for transcription.
