The audio for 海运 seems to be missing the n at the end to me.
I went to both Forvo and google to check how it’s pronunced in other locations, and I can hear it a full yun syllable there. But when listening on HH (I use the male voice at normal speed) I don’t get the ending I expect. Normal variation that I’m not used to? Or is the audio slightly wrong?
Yeah the male simplified voice for that “n” is barely perceptible.
For those curious, here it is:
I regenerated it and am deploying an update now (should be live in a couple minutes). Here’s what it will sound like once that is deployed:
白云 also seems to have the same issue (final un sound not being clearly pronounced).
I regenerated that as well (for male simplified voice). Will be deployed in the next hour or so.
