Ok, so you must break all 8 bit data into two 4 bit codes by shifting a word=8 bits four times to the right and strobe each when lined up...

You still need to send the initialize codes a 4 bit command code and a clear screen code before you send H=48 hex=> strobe in 1000 bin then shift right four times or swap nibbles and strobe 0100 bin now ready E=45h=> strobe in 0101 bin swap nibbles and strobe in 0100 bin etc etc L, L, O, space=20 hex .... You get the idea ??

Are you talking about text or voice recognition?
The later won't work on simple 8 bit processors.
