Check this back from time to time for new variants: https://github.com/espeak-ng/espeak-ng/issues/1581 You'll find a couple of new dragons there after the archive that I uploaded and shared here a while ago. I first created a separate issue for my own variants but then decided to merge variants by me and @gregodejesus for easier organization.
The previously non-klatt variants are still there so I don't get the point of this statement to be honest. One should always be able to pick whatever variant one likes so those extra klatt variants shouldn't be annoying.
Uh, don't know about that. But most of those klatt variants were not made by me already. @gregodejesus offered and tried to make klatt versions of my variants but then I preferred to preserve the non-klatt ones as well, so discarding them is not something I want either. So attached is my !v folder with all the variants it contains.
When I got my first computer in 2011 i used Jaws with Agata Polish Voice. About 2013 I switched to the Ivona Ewa. In 2014/2015 I switched to the ivona Jacek. About 2016 when I started using NVDA I switched to speechplayer in espeak, variant klatt. In 2019 I switched to the standard eSpeak variant Sandro.
At the end of 2022, I got the Apollo synthesizer and used it for about 4 months. Then the Apollo started to break down (something with the power supply, I think) and I put it aside until it was repaired. When I had Nokia E72 i used first Nokia Screenreader with Agata voice, second Talks with Nokia TTS voice. In iPhone SE i used first Zosia vocalizer and second Ewa compact voice (Vocalizer). I have Xiaomi now, and I use the software version of Apollo, which based on RHVoice engine. Unfortunately, the software version of apollo sounds much worse than the hardware version and does not speak so clearly.
For english I use a Polish espeak voice. I know, this may seems strange, but for me is normal. When I use an English synthesizer, it's either the British Daniel from Nuance or the Emma from Ivona.
I used also Apollo sometimes, but put it aside as I wrote.
This is a synthesizer from the 90s, when there were probably no human-sounding synthesizers yet. My Apollo have four languages: English, Polish, Russian and German.
