Signatures: Machine and Acoustic
A number of subareas have emerged from the work being carried out in forensic phonetics. Several undoubtedly are as much the responsibility of engineers as they are phoneticians. On the other hand, and as you probably have deduced, most phoneticians have a rather extensive background in acoustics, electronics (at least with relevant equipment) and computers—just as they do with concepts about human behavior, physiology and speech itself. As has been seen, they are involved in such technical issues as the decoding of tape recordings, electronic surveillance, the authentication of tape recordings, speaker identification by machine, and so on. Careers that routinely encompass work such as this naturally involve related activities.
