asterisk users - Nov 2019 - Simple, fast single-word offline free speech recognition in Asterisk (or as an AGI)?

I'm after fast, native recognition of the numbers 1 to 20, yes, no, menu
and help.

At the moment, I use Google Speech Recognition which uses no local
processing power, and is very accurate, allowing me to run on a very low
end VPS.

However, with the minimum of 15 seconds, numbers and words like "yes,
no"
soon eat up the 60 minute free allowance.

I was hoping I could use "local", with a fallback to Google speech rec
if
it was uncertain.

Any ideas? Thanks

Yes, I know I post similar back in January, but there was no response back
then and I was hoping things might have changed :)

I'm using IBM's Watson for voicemail transcriptions, they allow 500 
minutes per month for speech to text on the Free/Lite plan.  Maybe that 
could be used for a solution for you too.
