Like a previous reviewer stated- the other voice options are in the settings app- I bought this app solely because it advertised a UK Male voice option.
You cannot get any voice but UK Female or US Female to work.
The two female voices are very realistic- but this app is useless to me without the Male voice options it advertised.
Please developers- fix this issue and I will update my review to 5 stars
