Heavenly Spirit you can make your own especially as you say you want to use it for a personal project. If you have a microphone record whatever you want to say with windows sound recorder (I assume it is windows you have) Record what you want to say then go to save you will have to click on 'save as' then click change and it will allow you to change and save it in the format you are looking for PCM 8.000 khz 8 bit mono. Do not quote me lol but i am sure this will work in the talk designer.
