In this study we examine, if some kind of group features can be found in voice quality. We have formed two groups of speakers. Speakers with modal voice form group 1. Group 2 is formed by speakers with hoarse voice quality. We have tested, if the speakers, who are smokers, have different voice quality parameter values than the speakers who do not smoke. It was found out in this study that jitter and shimmer values do not give the answer to the question, whether it would be possible to measure voice quality parameters reliably in forensic cases.
