It looks like the script is complaining about the switch -A but I don't think that is the case. If HLEd was running it would produce a different message if it did not like the -A.

Test 1: what do you get from "which HLEd"

and if that works, what does bare command "HLEd" produce?

which HLEd gives this path...

/usr/local/bin/HLEd

sorry i didn't get this bare command can you please explain it.

Ok so you do have HLEd installed and the sytem can find it, good.

Now just run the command HLEd without any switches such as -A and so on and we will see what happens.

The message you are getting seems to imply that when you run HLEd with all the switches the system is ignoring the HLEd part and trying to run the first switch -A as a programme, which of course it is not.

without any switches means i didn't get exactly what command i need to run

i tried with only HLEd...i got this...

ubuntu@ub:~/Julius_Linux/voxforge/tutorial$ HLEd

Right, that output is expected. As you can see from this output, the instruction HLEd works and the switch -A is perfectly valid. What seems to be happening is that when your system sees the command

HLEd -A ...

it skips over the HLEd and tries to interpret the -A as the command for the line and very properly reports that it cannot find an executable by that name. It is very puzzling. I don't know how to explain how this happens, except perhaps that in a script the HLEd and -A have become separated by a newline. What suggestions do you have?

I am totally new to this...so i am following that instructions given that steps..but now i am stuck here so posted the question...what might be the solution for this...??

>ubuntu@ub:~/Julius_Linux/voxforge/tutorial$ $HLEd -A -D -T 1 -l '*' -d dict -i phones0.mlf mkphones0.led words.mlf
>-A: command not found

looks like you've typed in '$HLEd' as the command rather than 'HLEd'... please omit the dollar sign in front of HLEd (or any other command in the tutorial). tTe dollar sign is just there to indicate the bash prompt.

Bash interprets $HLEd as a variable, and since it is empty it tries to execute '-A' as a command and then borks...

oh ya... thanks for the reply...i removed the dollar and ran the command.

now  i am getting the follwing errors

HLEd -A -D -T 1 -l * -d dict -i phones0.mlf mkphones0.led words.mlf

No HTK Configuration Parameters Set

  ERROR [+5010]  InitSource: Cannot open source file mkphones0.led
  ERROR [+1210]  ReadScript: Can't open file mkphones0.led
 FATAL ERROR - Terminating program HLEd

When HLEd does not complain about dict, but does complain about other files, what does this say to you?
