Phonetic Cues Relevant to Drug Intoxication State Identification (Experimental Research)

This paper presents the results of analysis of perceptual auditory features enabling identification of drug intoxication states. The aim of the present investigation was to expand a set of personal characteristics of speech associated with the influence of drugs regarding Russian native female speakers. This paper presents preliminary results of the first stage of the investigation, the aim of which was perceptual auditory assessment of rambling speech (speech incoherency) by a set of parameters with regard to drug-intoxicated female speakers (opioid addicts) that can be regarded as distinctive features to be used for identification of drug-intoxicated speakers solely by their speech characteristics. At the present stage of the research, the perceptual auditory analysis method was used to single out the features relevant to drug intoxication identification. Further research is underway to establish automatically detectable acoustic correlates of these features.
