To which branch of crime-fighting would a musician be best suited? Forensic Phonetics? This programme features the tracking down of Weirside Jack – the Ripper Hoaxer – through recordings he made to taunt the police. There is also something amazing about background electrical hum and a mention of the effect on voices of use (and need) of heroin.
If you consider yourself to have a good ear, try your luck at the ‘voice identity parade’.
Meanwhile, this edition of Word of Mouth touches, amongst other things, upon the effect of alcohol on speech.
