Why would including synthesiser in the settings ring make it easier? That involves having to cursor to synthesiser in the ring, which could actually be a lot slower than just hitting NVDA+control+s. Even if you're already on the synthesiser setting in the ring, it's still only two less keystrokes and you can't use first letter navigation to speed up the selection process.

the synth ring remembers the current setting that you have changed. if you frequently change synth then it's just one shortcut away NVDA +shift +ctrl +down or up arrow

there's one third undesirable solution that involves creating yet a new key combination. I already found some unofficial addon to do just that, which I tweaked a little. here's the code for anyone interested:

import config
synth1 = config.conf['speech']['synth'] # 'eSpeak'
synth2 = 'vocalizer_expressive'

import globalPluginHandler
import ui
import globalVars
import synthDriverHandler

class GlobalPlugin(globalPluginHandler.GlobalPlugin):
    def script_toggleSynth(self, gesture):
        synth = synthDriverHandler.getSynth()
        if synth.name == synth1:
            synthDriverHandler.setSynth(synth2)
        else:
            synthDriverHandler.setSynth(synth1)
        ui.message(synthDriverHandler.getSynth().name)

    __gestures = {
    "kb:NVDA+shift+l":"toggleSynth",
}

thank you.

For the synthesizer in the settings ring part, this is a duplicate of #2590. Leaving it open due to the second idea.

Actually, I can't see a use case for having synthesizers hidden in the synthesizer dialog, since it allows first letter navigation as @jcsteh pointed out. Closing as duplicate for the first issue and a won't fix for the second one. But, feel free to provide a valid use case for the latter and we can consider reopening.
