Text to audio feature keeps cutting out first word of the slide notes

Hi, I’m new to Captivate & have been experimenting with typing in slide notes and then using the Text to Audio (Text to speech) feature rather than narrating the slides myself. However I am finding that the automated voice recording is snipping off the a little bit of the first word when you play it back. Has anyone else found this & is there a way of fixing it? Thanks in advance Liz
