Front end Problem

[andressr]

Hi,
I'm working with sphinx3 - sphinxbase, trying to build a recognition server for 8kHz speech. When the front end is initialized, i get this:

Initializing front end
INFO: fe_interface.c(287): You are using the internal mechanism to generate the seed.
FATAL_ERROR: "fe_sigproc.c", line 397: WTF, 4296.875000 < -15.625000 > 5031.250000

The config file i'm using is this:

-senmgau .cont.
-hmm ../telefono/telefono8k.cd_cont_1000_8
-lw 23
-feat 1s_c_d_dd
-beam 1e-120
-wbeam 1e-80
-dict ../telefono/telefono2.dic
-fdict ../telefono/telefono2.filler
-lm ../telefono/telefono2.arpa.DMP
-wip 0.2
-agc none
-varnorm no
-cmn current
-samprate 8000
-frate 100
-nfilt 31
-lowerf 130
-upperf 3500

this is the code, causing problems

fe_t *front_end;    
s3_decode_t decoder;

logm("Initializing decoder");
if (s3_decode_init(&decoder, config)) {
    fprintf(stderr,"Decoder Initialization failed.\n");
    exit(1);
    }

logm("Initializing front end");
front_end = fe_init_auto_r(config);

---

Thanks for any ideas or tips,

Andres

Thanks a lot for the tip, the problem was a mismatch (in the upperf value) between the general configuration file and feat.params

Your upperf argument is not applied (you could see that in log if you paste full one). The reason for this is probably a missing newline after
-upperf 3500
