Effects of Educational Context on Learners’ Ratings of a Synthetic Voice

Neasa Ní Chiaráin, Ailbhe Ní Chasaide

Studies suggest that the context in which synthetic voices are evaluated has a significant bearing on the evaluators' assessments of the voices. The present study is based on learners' evaluations of an Irish synthetic voice which is used in a Computer-Assisted Language Learning (CALL) context. Previous studies have allowed a number of extraneous variables, such as different voices being used or pitch or speech rate manipulations, to enter the study. The present study involves a single synthetic Irish HTS voice being evaluated in three different contexts, one of which is highly interactive, a second less so and a third which does not require the evaluator to perform any specific task. Results show that the voice was rated more favourably when presented in a highly interactive context. This finding has significant implications for the way we interpret the results of evaluations of synthetic voices.
