SUCCESS! LADSPA goodness is happening.
Of course as creative projects go, I decided not to go with a vocoder... but I didn't give up until I got it to work first!
Thank you everyone for the support. Here's the thank you song I promised at the resolution of my challenge. :D
With vocoder, blended with voiceover as it was harder to understand vocoded words on their own after several variation trials (good for a future project though):
With voiceover only, I personally like it better for my fun thank you song project:
Steps to make it work:
====
#where my plugins live
export LADSPA_PATH=/home/ec2-user/plugins
#ensure formant (mono voice) and carrier (mono pitch) audio files are set to the vocoder plugin's requirements
sox formant.wav -b 16 formant1b.wav gain -1 rate 44100 dither -s
sox carrier.wav -b 16 carrier1b.wav gain -1 rate 44100 dither -s
#merge mono formant and carrier into a single audio stereo file left and right channel
sox -M formant1b.wav carrier1b.wav formant_carrier.wav
#apply ladspa plugin via ladspa utilities directly
#!!! I'm stuck on how to make this work as part of sox, this gets the job done directly though
applyplugin formant_carrier.wav final.wav vocoder vocoder 16 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

If interested to see what the song mention of Patreon is about (basically a glorified tip jar to support electronic music habits), you're welcome to preview it here, going live later this month:
Thanks for what you do!
Kind regards,
Chris
