Subtitles-based Lip Sync

Hi, I can’t seem to get this plugin to work. I followed the video tutorial and the only major differences is I’m using composite phonemes rather than simple morph targets (I do have the “Use Composite Morph Targets” flag enabled) and I’m triggering the “Speak” function automatically after a delay rather than with a key press as is done in the video. Even still, audio doesn’t even trigger with the “Speak” function, and audio works fine if I use the built in “Play” function. I do have the experimental audio plugin enabled. I’m on version 4.19.2.
