i tried a different approach

Your trying to use Intel/AMD based make/install scripts on an ARM-based device (RaspberryPI uses an ARM CPU)

You shouldn't need HTK on your raspberrypi.

HTK is used for _training_ Acoustic Models, and this process creates a large text file.  You can do this on your computer.

Julius uses this file as input for recognizing speech.  You will need to install Julius on your raspberry pi.

Hiya! 
Thanks for the tip!  It is a bit of a no brainer hahah

I threw together a mint VM and hit this snag:

john@john-VirtualBox:~/htk$ make all
(cd HTKLib && make HTKLib.a) \
  || case "" in *k*) fail=yes;; *) exit 1;; esac;
make[1]: Entering directory '/home/john/htk/HTKLib'
gcc  -m32 -ansi -D_SVID_SOURCE -DOSS_AUDIO -D'ARCH="x86_64"' -Wall -Wno-switch -g -O2 -I. -DPHNALG   -c -o HGraf.o HGraf.c
In file included from HShell.h:40,
                 from HGraf.c:54:
/usr/include/stdio.h:27:10: fatal error: bits/libc-header-start.h: No such file or directory
   27 | #include <bits/libc-header-start.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[1]: *** [<builtin>: HGraf.o] Error 1
make[1]: Leaving directory '/home/john/htk/HTKLib'
make: *** [Makefile:96: HTKLib/HTKLib.a] Error 1

looks like i'm missing some dependancies... but there's nothing in the adapt guide that suggests what those might be.  Any ideas?

i was able to clear up the errors with some throwing spaghetti at the wall shenanigans.
I hit the '8 spaces did you mean a tab' error on line 77 but i've seen posts for that.  If anyone reading this wants to be a awesome and be like 'oh, just twiddle this bit right here' and get me outta the woods so i can get back to work on the pi i'd be super appreciative.

>fatal error: bits/libc-header-start.h: No such file or directory

you likely need to install the developer package for libc
