Trouble adding closed caption in Storyline to files that already have recorded audio

Hi Sandeep,

Thank you so much for these instructions. Once I selected the Audio option from the timeline, I was finally able to see the Options tab. I was able to go in and edit the captions for each slide.   However, prior to my re-recording of the audio for the slides (with my own voice), I had used one of the computer generated voices and I had selected the option to allow for the "text to speech" captions. I was able to successfully record my voice over the computer generated voice (since my colleagues and I felt that was a better way to go) and I also made a few changes to the text in my audio recording. I followed your instructions to go in edit the captions and I was able to do that. However, when I previewed the revised project, I did not see the revised captions that I added (using the process above) and which reflect the revised audio recording. I am still seeing the "text to speech" captions that were generated from the computer generated voice (I had used the Joanna voice and checked the box that says "Generate Closed Captions". Do you have any advice on how I can get rid of these closed captions so the ones I just revised (and match the revised audio) will display?  Any additional help is appreciated. 

Thanks,

Dana
