On the Influence of Alcohol Intoxication on Speaker Recognition

چکیده
In this paper we present a study of the influence of alcohol intoxication on an automatic speaker verification system. It is widely known that alcohol intoxication affects one’s speech in many ways, but it remains to be studied how well a system can recognise a person affected by alcohol intoxication. Using the Alcohol Language Corpus as speech database and a text-independent GMM-UBM speaker verification system, we perform experiments to analyse the effects of alcohol intoxication in detail. In different experimental setups, using recordings in either sober or alcoholised condition for speaker enrolment or testing, the influence of intoxication on the error rate of the speaker verification system is investigated. Compared to the baseline experiment without alcohol intoxication, the results indicate a generally negative influence of alcohol intoxication on the verification system. This influence is larger for female speakers compared to males.

Use of prosodic speech characteristics for automated detection of alcohol intoxication
In this paper we describe our methodology for automatic detection of speaker alcoholization. Our task is restricted to detection of considerable alcoholization (alcohol blood level ≥ 0.8 per mille), so that a two-class classification problem is to be solved. In particular, our attention is focused on the influence of the alcohol intoxication on the prosodical aspect of the spoken language. A ne...
متن کاملSpeaker Adaptation in Continuous Speech Recognition Using MLLR-Based MAP Estimation
A variety of methods are used for speaker adaptation in speech recognition. In some techniques, such as MAP estimation, only the models with available training data are updated. Hence, large amounts of training data are required in order to have significant recognition improvements. In some others, such as MLLR, where several general transformations are applied to model clusters, the results ar...

متن کاملAnalysis of voiced speech excitation due to alcohol Intoxication
A significant part of information carried in speech signal refers to the speaker. This paper deals with investigating alcohol intoxication based on analyzing recorded speech signal. Speech changes resulting from alcohol intoxication were investigated in the waveform of glottal pulses estimated from speech by applying the Iterative Adaptive Inverse Filtering (IAIF). Experimental results show tha...
