Influence of TTS Systems Performance on Reaction Times in People with Aphasia

Text-to-speech (TTS) systems provide fundamental reading support for people with aphasia and difficulties. However, artificial voices are more difficult to process than natural voices. The current study is an extended analysis of the results a clinical experiment investigating which, among three digitised human voice, suitable impairments. Such show that voice synthesised Ogmios TTS, concatenative speech synthesis system, caused significantly slower reaction times other used in experiment. present explores whether what quality metrics linked delayed times. For this purpose, were analysed using automatic assessment intelligibility, naturalness, jitter shimmer parameters. This revealed general, performed worse all These observations could explain impairments when listening TTS open up consideration about which choose compensative devices these patients based on
