Simplerec tutorial

From Sphinx

• Complete Sphinx3 Speech Recognition Quick Start because speech data files will be needed for this tutorial.

• Install sphinx3 trunk (version 0.7). NOTE: sphinx3 v. 0.6.3 will not work for this tutorial.

• Complete PortAudioPlayRec tutorial

• Download SphinxSimpleRec.zip to /usr/src and extract.

• Edit makefile
  • Near the top of the file, add the line
    • CMU_ROOT=$SPHINX_ROOT/sphinx3
  • add -I/usr/src/sphinx/sphinxbase/include to INC variable

• Edit wsj_5k_rec.cfg
  • delete -mdef, -mean, -var, -mixw, -tmat variables and their values
  • add -hmm $SPHINX_ROOT/sphinx3/model/hmm/hub4_cd_continuous_8gau_1s_c_d_dd
  • replace the -dict, -fdict, -lm values with the values used in Sphinx3 Speech Recognition Quick Start
  • delete -feat, -lw, -wip, -beam, -wbeam, -pbeam, -maxhmmpf, -maxwpf, -maxhistpf, and -outlatdir params

• Build

make

• If make fails, you may have to edit /SphinxSimpleRec.cpp, line 66 thus:

   	if (cmd_ln_parse_file(S3_DECODE_ARG_DEFS, argv[1] , 0) )

• Run the software

./SphinxSimpleRec wsj_5k_rec.cfg

Hit enter, wait for the beep to finish, then speak one of the words in the vocubulary: hello, please, or yellow.
