In this report we consider the possibility that speech analysis techniques may be used to determine whether an individual was intoxicated at the time that a voice recording was made, and discuss an analysis of the speech produced by the captain of the Exxon Valdez recorded at several points around the time of the accident at Prince William Sound, Alaska. A review of previous research on the effects of alcohol and other effects on speech production suggests that it may be possible to attribute a certain, unique pattern of changes in speech to the influence of alcohol. However, the rate of occurrence of this pattern or the reliability of a decision based on observations such as these is not known. Acoustic-phonetic analysis of a small number of tokens of Captain Hazelwood's speech recorded before, during and after the accident revealed a number of changes in speech behavior which are similar to the pattern of changes observed in previous laboratory-based research on the effects of alcohol on speech production. We conclude with a discussion of the limitations in making inferences concerning the state of the speaker upon the basis of phonetic data and then discuss several possible explanations of the pattern of change found in the recordings of Captain Hazelwood.
在本报告中，我们探讨了语音分析技术用于确定在进行语音录制时个人是否处于醉酒状态的可能性，并讨论了对埃克森·瓦尔迪兹号船长在阿拉斯加威廉王子湾事故发生前后几个时间点录制的语音进行的分析。对先前关于酒精及其他因素对语音产生影响的研究回顾表明，或许有可能将某种独特的语音变化模式归因于酒精的影响。然而，这种模式的出现频率或基于此类观察结果做出判断的可靠性尚不清楚。对事故发生前、期间和之后录制的少数哈泽尔伍德船长语音样本进行的声学语音分析揭示了语音行为的一些变化，这些变化与先前基于实验室研究酒精对语音产生影响时观察到的变化模式相似。我们最后讨论了基于语音数据推断说话者状态的局限性，然后探讨了对哈泽尔伍德船长录音中发现的变化模式的几种可能解释。
