do you have the source file pocket_continuous

[Jolyxie]

hello :
do you have the source file of the pocketsphinx_continuous?
why the result of "./hello_ps " is always the same :goforward ten meter .....
how can the "hello_ps" works like "pocketsphinx_continuous" ?????

hello_ps.c

include <pocketsphinx.h></pocketsphinx.h>

define MODELDIR "/usr/local/share/pocketsphinx/model"

int main(int argc, char argv){
ps_decoder_t ps;
cmd_ln_t config;
FILE fh;
char const hyp, uttid;
int16 buf;
int rv;
int32 score;
config = cmd_ln_init(NULL,ps_args(),TRUE,
"-hmm",MODELDIR"/hmm/en_US/hub4wsj_sc_8k",
"-lm",MODELDIR"/lm/en/turtle.DMP",
"-dict",MODELDIR"/lm/en/turtle.dic",NULL);
if (config == NULL) return 1;
ps = ps_init(config);/initialize the decoder, use ps_init/
if (ps == NULL) return 1;
/Decoding a file stream/
fh = fopen("goforward.raw", "rb");

if (fh == NULL) { perror("Failed to open goforward.raw"); return 1; }

/decode it, using ps_decode_raw():/
rv = ps_decode_raw(ps, fh, "goforward", -1);

if (rv < 0) return 1;
/to get the hypothesis(假设), we can use ps_get_hyp():/
hyp = ps_get_hyp(ps, &score, &uttid);

if (hyp == NULL) return 1;

printf("Recognized: %s\n", hyp);

fseek(fh, 0, SEEK_SET);
/start the utterance using ps_start_utt()/
rv = ps_start_utt(ps, "goforward");

if (rv < 0) return 1;
while (!feof(fh)) {
size_t nsamp;
nsamp = fread(buf, 2, 512, fh);
rv = ps_process_raw(ps, buf, nsamp, FALSE, FALSE); }
rv = ps_end_utt(ps);
if (rv < 0) return 1;
hyp = ps_get_hyp(ps, &score, &uttid);
if (hyp == NULL) return 1;
printf("Recognized: %s\n", hyp);
fclose(fh);
ps_free(ps);
return 0;
}

thank you very much!!

do you have the source file of the pocketsphinx_continuous?

pocketsphinx/src/programs/continuous.c

why the result of "./hello_ps " is always the same :goforward ten meter
.....

Because it recognizes audio from the file containing this phrase. It doesn't
recognize audio from microphone

how can the "hello_ps" works like "pocketsphinx_continuous" ?????

If the source code of hello_ps will do the same as pocketsphinx_continuous is
doing, the hello_ps will work the same way.

oh~~~i know more,,,,thank you !

[Jolyxie]

oh ,yes
i have one more question :
can the pocketsphinx be use to ARM,(the system is linux)???
use arm-linux-gcc~ to compile it ~~
or whether it should change something?

[Nickolay V. Shmyrev]

can the pocketsphinx be use to ARM,(the system is linux)???

Yes

use arm-linux-gcc~ to compile it ~~ or whether it should change something?

Google for cross-compiling guide, there are quite many of them.

hello,nshmyrev

i have try it ,but the termina show that :

make

arm-linux-gcc recognise.c -o recognise -DMODELDIR=\
"/usr/local/share/pocketsphinx/model \ "-I/usr/local/include
-I/usr/local/include/sphinxbase -I/usr/local/include/pocketsphinx
-L/usr/local/lib -lpocketsphinx -lsphinxbase -lsphinxad
/usr/local/arm/4.5.1/bin/../lib/gcc/arm-none-linux-gnueabi/4.5.1

/../../../../arm-none-linux-gnueabi/bin/ld: cannot find -lpocketsphinx
collect2: ld returned 1 exit status
make: *** Error 1

i spend a lot of time and try to solve it ,but fail ...... what i know is that
the sphinxbase and pocketsphinx should fix to
the version arm-linux-gcc
because the version of sphinxbase i installed was only fix the PC linux
so whether should i install the sphinxbase again which fix arm-linux-gcc???
or how can i install this kind of pocketsphinx?

thank you for you time ......

As I wrote above you need to read cross-compilation documentation to
understand the basics of cross-compilling software. You also need to read the
compiler documentation to understand how compiler works and what all those
flags like -L mean. The command line you are currently using is not correct,
once you read the documentation you will be able to fix it.

oh ~~yes~~i will !!
thanks a lot
