Abstract: This thesis has three main objectives. The first objective (A) includes Study I, which investigates the parameter fundamental frequency (F0) and its robustness in different acoustic contexts by using different measures. The outcome concludes that using the alternative baseline as a measure will diminish the effect of low-quality recordings or varying speaking liveliness. However, both creaky voice and raised vocal effort induce intra-variation problems that are yet to be solved. The second obje... more
