Are they? I guess not….
It could be an actual phonetic phenomenon where a preceding glottal stop contributes to the tensedness, or it might be just a quirk of SynthV’s implementation. I’m leaning towards the latter, as I barely feel any glottal stops, making those tense Korean consonant sounds myself.
cl phoneme might be a “sokuon”
David Cuny: I found some information on “extra” phonemes included with Solaria in an undocumented script that was included with the voicebank. Of course, if you didn’t have the Pro version and didn’t think to load the script, you’d never know about them.
cl (Stop/Glottal Stop) - a phoneme you can insert to have the vocal perform a stop,
cl can be used to accurately input words like uh-oh or used for singing effect. In some AI voice libraries, a
cl between or before vowels will sometimes cause the library to perform a vocal fry, this is context dependent, but can provide a unique effect.
Bellerandre: Next, it helps to know how to activate phoneme view on your notes, and how to check them in note properties. In my SynthV (studio 1.05 - with Saki full), typing “
But” shows the phonemes “
b a cl.”
Given that SynthV is designed mainly for the Japanese (and Chinese) articulation, I suspect that SynthV’s poorly documented
cl phoneme could be more of a Japanese “sokuon (促音/촉음),” that is, a “っ/ッ,” rather than a simple glottal stop. — I haven’t used SynthV and have no proofs to back this up; inquire the developers about this….
A sokuon is known to (usually) double the following consonant and reduce the voice onset time (VOT), getting it closer to a tenuis, a zero-VOT consonant. Because of this, it has often been used to transcribe 된소리/경음, the tense Korean consonants, in Japanese. It is also, sometimes, but not always, realized as a glottal stop in certain circumstances.
cl phoneme is a sokuon, SynthV producing those tense (“of a reduced VOT”) sounds for
cl-prepended phoneme sequences does make sense, and it also makes sense that many people described it as a “glottal stop,” which is only partially true. My hypothesis. What do you think?
I don’t think those Korean tense consonants involve glottal stops. I believe that the
cl, what you think is a glottal stop, is actually not a glottal stop, but a Japanese sokuon, which usually reduces the VOT of the following consonant and make it sound tense, and sometimes becomes a glottal stop to confuse you.
