A professional impersonator has been studied when training his voice to mimic two target speakers. A threefold investigation has been conducted; a computer-based speaker verification system was used, phonetic-acoustic measurements were made and a perception test was conducted. Our idea behind using this type of system is to measure how close to the target(More)
This paper investigates the effect of gender on voice onset time distribution at three stages of speech development. Two subject groups consisting of children, aged approximately 3 and 9 years, were compared to adult speakers regarding voice onset time of initial plosives. The results showed significant gender effects in the aspirated plosives in the young(More)

However, whether perceived age can act as a distracter for voice(More)
