Also, I found some words worked really well and others were unreliable (this probably depends on the microphone, the soundcard and the voice of the user etc)

Here is a list of the words I found that work pretty consistently so far:

negative (pronounce the t clearly)
affirmative (pronounce the t clearly and roll the r slightly as Americans do)
yes
no
right
down
north (roll the r slightly as americans do)
program
clear
again (pronounce "agen" not "agayn")
welcome
beginning
screen
return (roll the r slightly as americans do)
absolutely
music
internet (pronounced as "innnternet" as Americans would. Roll the r slightly)
one
four (roll the r slightly as americans do)
six
self
finish
fiction
america
Out house

Avoid start and stop as they are too easily confused.

Code: Select all

#!/bin/sh
file="inputtxt"
pocketsphinx_continuous | while read LINE; do
case "$LINE" in
  echo "$LINE" >> "$file"
done
im sure that to output the line into a file we want to do something like this, but im not getting something quite right here. syntax...

i have created a script in the usr/bin folder and given it the above code to chew on, but im getting no joy as yet. ill figure it out tho...might take me a minute to nail down but ill get it.

if any other code monkey wants to jump in and tell me my syntax error i would not complain...feel free! but this is not so tough and ill untangle it sooner or later.

this isnt doing it either, but i think im getting closer...

this...

Code: Select all

#!/bin/sh
pocketsphinx_continuous | while read LINE; do
$LINE > test.txt  
done
...is a whole lot closer. still not right, but it does get sphinx running and makes some change to the txt file (everytime sphinx registers a word the files contents change i can tell because geany asks me to reload the more recent page) but it is still empty each time...so j still have a syntax error somewhere.

I will keep peckin away at it until i get it right. :)

Bearing in mind I have no idea what I'm talking about - should the test.txt have more path info? Like /usr/bin/test.txt or something to ensure correct permissions? Or maybe there should be some quote marks " " somewhere?

And "case" / "esac" not required?

Just looking back at this code, is there an "esac" missing? (hope you don't mind my uneducated guesses.....)

'case' must close with 'esac':

Code: Select all

case $SOME in
  *) : ;; #if more than one entry, then each should end with double';'
esac

Just a small point, but if something is in /usr/bin/, you don't need to cd into it to run it (assuming it is executable).
Open any old terminal and type 'poc' then hit the tab key for autocompletion.

I had a look at these resources:
http://unix.stackexchange.com/questions ... nto-a-file
and
http://unix.stackexchange.com/questions ... -to-stdout
and they seem to be trying to do something similar to what we are wanting. I tried following the program > /path/to/file syntax and got the following:

Code: Select all

#!/bin/sh
pocketsphinx_continuous  > /root/test.txt &
which DOES seem to create my /root/test.txt file and it does contain the text I want.

Couple of things to note:
1) The "READY" no longer displays in the pocketsphinx terminal (although that doesn't seem to stop it running...) and the rest of the text in the terminal does not display in thetext file (which is handy because it is only the decoded text just before the READY prompt that we want anyway...)
2) If I open the test.txt file with Geany I can keep selecting "File, Reload" to see the updated decoded words.

how right you both are. im uneducated guessing here too, you understand...

it seems to me that after seeiing how this...

Code: Select all

#!/bin/sh
pocketsphinx_continuous  > /root/test.txt &
...creates information in the file, we need to add another line or two to that to omit the
READY....
Listening...
Stopped listening, please wait....
part.

i will start working on that next. :D

it seems like we need to use grep to search the test.txt file for our "spoken command"; someething like this....

Code: Select all

!/bin/sh
pocketsphinx_continuous  > /root/test.txt &
if grep -q "yes" /root/test.txt; then
     peasymp3autoplay /path/to/Music 
fi
done
..but of course, that code does not do it. evidently i am FANTASTIC at writing code that does not work!

any thoughts?

Probably hundreds of better ways of doing this, but it does have some effect:

Code: Select all

 awk '/^0/  { print $2 }' ~/test.txt
This extracts the spoken command (assuming a single word).
It just finds a line beginning with a '0' eg 000000001:, then prints out the next field.
Contents of test.txt:

Code: Select all

READY....
Listening...
Stopped listening, please wait...
000000000: hello
READY....
Listening...
Stopped listening, please wait...
000000001: bye
READY....

Just outputting to test.txt, there will be several words, as the file gets constantly written to, so it probably needs to be done 'on the fly'.
(thats not genuine output BTW, not had chance to test recognition properly)

The word then needs passing to something like:

Code: Select all

case  $wot_u_said in 
        browser)
        defaultbrowser
        ;;
        shutdown)     
        shutdown
         ;;
  esac         
}

I think what I would be wanting to do is this:

1) Identify the most recent instance of "READY" in the file (assuming the file may at times have pages of chatter in it...)
2) "Grab" the text that is found between that "READY" and the colon that precedes it.
3) Strip out any leading and trailing spaces.
4) Use the remaining text as our command keyword.
5) Clear the file.

I've got a bit of research to do... :-)

Thanks Keef, I didn't spot that before I posted. I will have a tinker with your code tonight.

EDIT : Could your awk script be changed to allow it to detect the "READY" string and then grab the data field BEFORE it? (I'm thinking that would ensure we were not trying to grab the data field before it was finished being written)

EDIT2 : Is there a risk involved in trying to have two programs accessing the same file? ie: what if sphinx is trying to write new data to the file while I am trying to use another program to clear the data. Do I need to handle the potential conflict resolution or does the system code handle that somehow by making one program wait politely? (and if so - how does it determine which program gets the priority?)

I gave your awk code a try and it works well on a live file - I decided to change it to:

Code: Select all

 awk '/^0000/  { print $2 }' ~/test.txt
just so there was less chance of it picking up any other "0" that happens to get thrown in there (probably unnecessary but I feel it's more selective to look for the "0000" string)

So now the problem is to clear the file at the right time so that only a single instance is captured (last response only). (Or how to discard everything except the last line captured...?)

All I can do is have a good look at Grep, Awk and Sed and try to figure which is the best way to force discarding of everything except the most recent command word.

All suggestions truly welcome.

Well, I've got some steps that seem to work, but I haven't combined them into an elegant form yet. Here are the steps I have been trying just as single scripts:

This first step gets pocketsphinx_continuous to run and build a chatdump file:

Code: Select all

#!/bin/sh
pocketsphinx_continuous  > /root/chatdump.txt &
This creates a raw "chatdump" file containing things like this:

Code: Select all

Listening...
Stopped listening, please wait...
000000001: Out house
READY....
Listening...
Stopped listening, please wait...
000000002: program
READY....
Listening...
Stopped listening, please wait...
000000003: beginning
READY....
Then I use Keefs awk to extract the recognised command word from each valid line as follows:

Code: Select all

#!/bin/bash
awk '/^0000/  { print $2 }' /root/chatdump.txt > /root/chat_extract.txt &
This creates a file called chat_extract.txt containing the following:

Code: Select all

Out house
program
beginning
Then I extract just the final word from this file as follows:

Code: Select all

#!/bin/bash
sed '$!d'  /root/chat_extract.txt > /root/chat_command.txt &
Which extracts the final spoken command (in this case "beginning") and lists that single word in a file called chat_command.txt

Of course this is limiting commands to a single word, but that is where I want to start. (Then the TTA protocol/menu can easily reject any meaningless command and only permit a small range of actions that it is programmed for)

At least by picking out the final word in the file I don't need to panic about clearing the chatdump file regularly yet.

Don't laugh folks - at least I feel like I'm making progress. Baby steps!
