How do I know a result is generated from a purposeful voice or a noise? use the score1? but I found that the score of the purposeful voice and the score of the noise are nearly the same.where is the bounds? is there another way? thanks noise's result -------------------------------------- pass1_best: <s> <n><num>1</num>ZYF</n> pass1_best_wordseq: 0 2 pass1_best_phonemeseq: sil | jh ow r er n f aa pass1_best_score: -10684.339844 length: 318 frames (1.06 sec.) ### Recognition: 2nd pass (RL heuristic best-first with DFA) samplenum=318 sentence1: <s> <n><num>3</num>ZMY</n> </s> wseq1: 0 2 1 phseq1: sil | jh aa ng m ae ng y iy | sil cmscore1: 1.000 0.639 1.000 score1: -13599.010742 6 generated, 6 pushed, 4 nodes popped in 318 purposeful voice --------------------------------------------------------- pass1_best: <s> <n><num>1</num>ZYF</n> pass1_best_wordseq: 0 2 pass1_best_phonemeseq: sil | jh ow r er n f aa pass1_best_score: -12398.662109 length: 386 frames (1.28 sec.) ### Recognition: 2nd pass (RL heuristic best-first with DFA) samplenum=386 sentence1: <s> <n><num>2</num>LDH</n> </s> wseq1: 0 2 1 phseq1: sil | y ow b aa hh aa | sil cmscore1: 1.000 1.000 1.000 score1: -14228.536133 8 generated, 8 pushed, 4 nodes popped in 386 http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/run-julian/comments/how-to-discard-useless-result Mon, 19 May 2008 21:30:25 -0500 http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/run-julian/comments/how-to-improve-recognition If you have a small grammar, the following things can help improve recognition performance: using a noise model, using word-based hmm with more states (rather than phone-based hmm), not using context-independent models http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/run-julian/comments/how-to-improve-recognition Fri, 18 Apr 2008 14:04:48 -0500 http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/tutorial/run-julian/comments/congratulation Thanhs a lot for this tutorial, It is a really good help to start using SRE. I do the tutorial and in fact I am not really satisfied of the Julian Result. He recognize less than one sentence on four. Quite bad result no. I record the sample using audacity at a sample rate of 98000Hz. Maybe it is the cause of my problem, what do do think ? But I don't forget to change the sampling rate in Jconf. What shoulld I do to improve the recognition.

I am really supported by your answers on my questions. Now, I have already trained several Indonesian audio files to get hmm models. Then, I get language model, that is 2-gram language model (ARPA format), by using a tool provided in "http://www.speech.cs.cmu.edu/tools/lm.html". I use all of those models, acoustic model and language model, with Julius to test some speech. The content of jconf file (julius.jconf) I use is: -nlr model/grammar -v dict -h hmm15/hmmdefs -hlist tiedlist -gprune safe -input rawfile # ‰¹º”gŒ`ƒf[ƒ^ƒtƒ@ƒCƒ‹(ƒtƒH[ƒ}ƒbƒgŽ©“®”»•Ê) # Œ`Ž®FWAV(16bit) ‚Ü‚½‚Í # RAW(16bit(signed short),mono,big-endian) # 16kHzˆÈŠO‚̃tƒ@ƒCƒ‹‚Í -smpFreq ‚ÅŽü”g”Žw’è -filelist listfile.txt # ”FŽ¯‘Ώۃtƒ@ƒCƒ‹‚̃ŠƒXƒg -smpFreq 16000 # ƒTƒ“ƒvƒŠƒ“ƒOŽü”g”(Hz) -smpPeriod 625 # ƒTƒ“ƒvƒŠƒ“ƒOŽüŠú(ns) (= 10000000 / smpFreq) -demo # "-progout -quiet" ‚Æ“¯ When I run Julius by typing: "julius -C julius.jconf", there are errors (I show you the whole results) as follows: $ julius -C julius.jconf STAT: include config: julius.jconf STAT: jconf successfully finalized STAT: *** loading AM00 _default Stat: init_phmm: Reading in HMM definition Stat: rdhmmdef: ascii format HMM definition Stat: rdhmmdef: limit check passed Stat: check_hmm_restriction: an HMM with several arcs from initial state found: "sp" Stat: rdhmmdef: this HMM requires multipath handling at decoding Stat: init_phmm: defined HMMs: 23 Stat: init_phmm: logical names: 117 in HMMList Stat: init_phmm: base phones: 23 used in logical Stat: init_phmm: finished reading HMM definitions STAT: making pseudo bi/mono-phone for IW-triphone Stat: hmm_lookup: 92 pseudo phones are added to logical HMM list STAT: *** AM00 _default loaded STAT: *** loading LM00 _default Stat: init_voca: read 23 words Stat: init_ngram: reading in ARPA forward n-gram from model/grammar Stat: ngram_read_arpa: this is 2-gram file Stat: ngram_read_arpa: reading 1-gram part...

Can you help me to solve this problem?
