### 5/5 — Voice diversity for accents Needed

*2026-03-31*

I love the app itself and appreciate that Work is slowly being done on accessibility. However, with so many English AI voices available for both male and female I would love to see some accent markers used American British Indian so on and so forth. Most of the voices I have tested appear to be American English accented. Would love to see some added that had other accents as well. Need to work on voice over accessibility as well. I am aware it’s on the road map but would really love to see it made a priority as well as other accessibility features in general. Would love to know if it would be possible to share voice clones from the voice and PC app to this app for use in Book reading. Overall great app but as with everything room for improvement.
