@amberhinds To be fair to your step dad, Karen and Lee, the popular Australian voices found on most GPS devices, as well as on IOS, originally developed by Scansoft, later purchased by Nuance, then transferred to Cerence Automotive, before finally getting owned by Microsoft, are some of the nicest text to speech voices ever made for casual listening. Largely this is due to whomever was in charge of recording and curating the data back in 2002. They did an excellent job editing and aligning the recordings for use with the concatenative synthesis technology that was available at the time, resulting in the Australian voices sounding noticeably better than all of the other English options, even though they all used the same underlying methods. The fact the data capture was so high quality has meant that as technology and training methods improve, those voices have continued to remain a step ahead. The female version of the voice your father is almost certainly using is based on this woman: en.wikipedia.org/wiki/Karen_Jacobsen
If all of my favourite, fast and efficient voices were ripped away from me, those Australian voices are probably what I'd revert to. They're not as fast as I would like, but at least they're clear and accurate. Your step dad has good taste.
