Recogniser only works well on goforward.raw

[Benjamin Gorman]

So I have pocketsphinx set up and for the goforward.raw file it all works fine. Here is my set up line:

config = cmd_ln_init(NULL, ps_args(), TRUE, "-hmm", MODELDIR "/en-us/en-us", "-lm", MODELDIR "/en-us/en-us.lm.dmp", "-dict", MODELDIR "/en-us/cmudict-en-us.dict", NULL);

I tried it on this file (https://dl.dropboxusercontent.com/u/3865748/sx412.raw) and the result should be something like:

2130 8146 gwen
8146 16919 planted
16919 22433 green
22433 29409 beans
29409 31289 in
31289 33754 her
33754 42722 vegetable
42722 49406 garden

But I don't get anything like that, but the speaker is British so I assumed that's why.

Now for this file (https://dl.dropboxusercontent.com/u/3865748/214.raw) the speaker is american and it should be:

"We'll plant roses this spring"

But pocketsphinx gets:

Any idea what I'm doing wrong, I didn't expect it to be perfect as it's not got any real context to go on. But it seems something is going wrong.
