- Think I can do uvular trill
- Trying to do alveolar trill
- Can't distinguish what sounds right and what feels right, so having trouble using these metrics as useful feedback to determine progress
- How do I test if I'm actually doing an alveolar trill?
I'm sure there's countless posts about pronouncing the rolled R or alveolar trill, and I've watched many videos and read much advice – but I haven't found anything specifically providing a test to help one determine if they are indeed correctly performing the alveolar trill. There's advice on how to do it, but I can't find any advice on how to evaluate success.
In my particular case, it would be immensely helpful to have a mechanism by which to differentiate whether I'm performing an uvular trill or indeed actually performing an alveolar trill, which is my goal. I've listened to audio and can't hear whether the sounds I'm making are correct or not based on comparison with correct audio of the alveolar trill, as it sounds like it could be correct but just needs improvement or perhaps it's subtly wrong; and if I can't tell the difference this doesn't necessarily mean it is indeed correct, since I can do it consciously wrong as an uvular trill and similarly not hear a difference I'd be able to distinguish as uvular if I hadn't known I was doing an uvular trill. In terms of sensation, the consciously performed uvular trill has a distinct feeling flapping/vibrating in the back of my throat, kind of like gargling. When I attempt the alveolar trill, I keep my tongue loose and I can feel it vibrating in the location I believe is correct based on my research, and I hear a trill-esque sound, but I can't tell if it's the same sound as from the uvular trill, perhaps somewhat muffled by my tongue, and that the new sensation is of my tongue vibrating a bit from the air – and also making a slight S sound in the process – but such that it's merely coincident with the old source of the trill and not actually a new source of the trill noise – that is, I'm just doing an uvular trill again but with my tongue in a different place (which I know I can do by rigidly placing my tongue against the roof of my mouth and doing the uvular trill).
Is there some test I could perform to definitely determine if I'm performing an alveolar trill correctly, short of installing a camera in my mouth?
