AFTER THE AFTER THE HARD DRIVE CRASH WE TOOK THE TIME TO ACTUALLY REBUILD THE THE THE SYSTEM AND ACTUALLY TRAIN 'CAUSE ORIGINALLY WE SORT OF HAD THE IDEA OF OH WE'LL USE A RECOGNIZER THAT'S BEEN TRAINED ON A LARGE AMOUNT OF TELEPHONE SPEECH DATA AND THAT SHOULD GIVE US A BETTER RESULT I JUST AS A CONTRAST I TRAINED ONE SPECIFICALLY ON THIS DATA RESULTS WERE ALMOST IDENTICAL UM WHICH SAYS TO ME THERE'S SOMETHING WRONG WITH THE DATA RATHER THAN AND IT'S NOTHING SERIOUS IT'S SIMPLY THAT IT HASN'T BEEN UM CHUNKED IT OR OR SEGMENTED IN A WAY THAT'S TYPICAL OF SPEECH RESOURCES IN TERMS OF UM YOU CAN HAVE LIKE UH A TWO SECOND UTTERANCE UH CREDIT CARDS AND THEN TWENTY SECONDS OF SILENCE COMING AFTER IT WHICH IN WHICH WHEN YOU F WHEN YOU FIRST THINK ABOUT IT YOU JUST THINK OH SILENCE WHATEVER NOTHING WILL HAPPEN BUT A LOT OF THE NORMALIZATION THAT WE USE UH YEAH C. M. S. C. C. V. N. UH SO W WE NEED A DECENT END POINT DETECTION SYSTEM RUNNING BEFORE WE CAN WE CAN WE CAN DO THAT AND WE'RE CONVERGING ON HAVING ONE NOW JUST IN IN SORT OF TANDEM WITH THIS DEVELOPMENT OF THIS WEB BASED RECOGNIZER UH YE YEAH UM BUT I I THINK WE SHOULD SEE A DECENT SORT OF IMPROVEMENT THEN NOT JUST IN TERMS OF NO LONGER HAVING RECOGNITION ERRORS WHENEVER SILENCE APPEARS 'CAUSE YOU GET THAT IMMEDIATE BENEFIT THAT YOU DON'T HAVE ANY INSERTION ERRORS BUT ALSO IT SHOULD ACTUALLY AFFECT THE RECOGNITION ON THE SPEECH SEGMENTS AS WELL IT IT IT'S NON DETERMINIST SO SOMETHING THAT REALLY TAKES THIS AND THEY RECOGNIZE ONLY THAT UH THAT PART THIS WILL IMPROVE THE PHONEME UH RECOGNITION RATE MM THAT'S THE HARD P OH I MIGHT UH GIVEN THE TROUBLE WE'VE HAD WITH THIS CORPUS I CAN'T MAKE ANY PROMISES YEAH EXA THAT'S THE INTENTION THERE UH SURE MM YE LIKE THERE WERE THERE WERE SIX THOUSAND UTTERANCES THAT WEREN'T USED FOR UH THE CALL ROUTING SIDE OF THINGS I THINK THEY TH THERE WERE THIRTEEN THOUSAND IN THE ENTIRE CORPUS SIX T HALF OF THEM ROUGHLY WE'VE THROWN AWAY SO USE THAT FOR ACOUSTIC TRAINING AND THE RESULTS FROM THAT WERE ALMOST THE SAME AS WHAT WE GOT FOR THE C. T. S. MODEL NO NO NO NO NO IT I BUILT IN END POINT DETECTION ET CETERA ET CETERA SO SO MAYBE LIKE WE HAD TO DO THIS END POINT DETECTION AND PROBABLY A LITTLE BIT OF FINAL FILTERING AND THEN I THINK YOU SHOULD BE PRETTY MUCH CONVERGING TO THE SYSTEM BUT THE STILL THE REASON WITH THE THE THEY HAD LIKE WHAT ARE THE SYSTEMS WE TRAIN ON DATABASES ARE THEY ARE CHOP NEATLY THAT THERE IS NOT TOO MUCH SILENCE BEGINNING NOT TOO MUCH SILENCE AT THE END THEY ARE THEY ARE J THEY THEY CHOPPED SO NEATLY FOR THE IT LIKE CUSTOM MADE DATABASE BUT UH HERE IT'S NOT LIKE THAT YOU KNOW LIKE UH-HUH YEAH YEAH YEAH YEAH YEAH I SEE I SEE THE PROBLEM LIKE ONE THING IS LIKE WE CAN DO THIS BEGIN AND END DETECTION AS WE SAID OR YOU AND HE CAN UH WE CAN TRY TO USE UH FRANCE TELECOM'S UH APPROACH ACTUALLY AND THAT UM UH UH THEY THEY HAVE THIS FRONT END WHICH UH UH WHICH WHICH CAN DO A SPECTRAL AND PLUS IT CAN GIVE YOU A VOICE ACTIVITY DETECTION PART F PART FROM BASIS IT CAN GIVE SO SOMETHI WE CAN JUST YEAH WE CAN JUST RUN IT QUICKLY AND SEE AND PROBABLY YOU WILL HAVE TO RUN IT WILL GIVE YOU THE IDEA THAT IS IT OKAY LIKE YEAH NO NO NO NO UH NOT RUNNING I MEAN TO SAY P PROBABLY UH HE SHOULD RUN IT OR UH LIKE WE CAN GE HELP HIM TO RUN IT ACTUALLY BECAUSE AT SOME POINT HE HAS TO GET INTO UH I'M NOT NOT SURE IT'S YEAH I'M LOSI WE HAVE ALL THE SCRIPTS BUT PROBABLY UH HE SHOULD RUN IT I MEAN TO SAY I DON'T KNOW YEAH WHATEVER I DON'T KNOW THING TH I DON'T KNOW WHETHER THAT A THE ALL THESE EXPERIMENTS PROBABLY FOR THE THE THE CALL ROUTING ITSELF OR THE RECOGNITION UH THE PHONEME RECOGNITION UH FOR TO MAKE IT FASTER WE SHOULD RU IT RUN MAYBE IF WE RUN F WE OURSELF IT IT'S VERY FAST UH YEAH YEAH NO MM-HMM I HAVE ALL UH JEAN YVES'S UH SCRIPTS AND UH PROGRAMS FOR PERFORMING THE CALL UH ROUTING I THINK UH STARTING FROM THE PHONEME SEQUENCES YEAH OH SURE BUT I MEAN THE SCRIPTS ARE SO AUTOMATED IT'S JUST A MATTER OF SITTING UH UH SUBMITTING A JOB TO THE CLUSTER AND YEAH I I KNOW THAT I DON'T KNOW HOW TO USE THE CLUSTER I DON'T MIND RUNNING IT THAT'D IT'D BE LIKE UH HALF AN HOUR'S WORK IN A DAY TO RUN THE RECOGNITION SCRIPTS I MEAN I I I I KNOW YOU'RE SAYING ARTEM SHOULD FAMILIARISE HIMSELF WITH THE A. S. R. SYSTEMS OR WHATEVER FINE BUT I DON'T UH I D I DON'T THINK THIS IS A POINT THAT'S WORTH SORT OF WORRYING ABOUT AT THIS STAGE ANYWAY I MEAN YEAH IF IT'S JUST RUNNING A SCRIPT I DON'T KNOW IF IT'S YEAH THAT UH-HUH NO NO NO NO I THE END POINT SYSTEM IS DIFFERENT THING NO THAT'S AND WE NEED IT FOR AMI PLUS OTHER THING AND SO BUT THE I AM TO ALL SAYING YEAH I I AM BUT THIS IS BASICALLY DETECTING SPEECH AND NO NON SPEECH IT'S N IT UH NO NO NO IT'S NOT SPEECH NON SPEECH UH UH IT'S UH IT'S UH IT'S YEAH THAT'S THE PROBLEM IT'S AND IS IT'S SPEECH AND AND OKAY IT'S UH YOU CAN SAY THAT'S VERY YEAH MM-HMM AND THIS IS WHAT EVERYBODY SORT OF CLAIMED THE PROBLEM WAS SOLVED WITH YEARS AGO BUT BUT WHO REALLY CAN DO UH WHEN SOMEBODY WILL REALLY BE ABLE TO DO THAT I MEAN DETECT THE SPEECH FROM NON SPEECH IT WILL BE A LITTLE REVOLUTION NO IN THE BUT I MEAN THIS IS ONCE AGAIN A VERY CONSTRAINED TASK AGAIN I MEAN IT'S IT'S IT'S YOU YOU'RE ALMOST ASSURED IT'S ONLY GONNA BE A SINGLE SPEAKER ON THE MICROPHONE SO I MEAN THE THE ONLY SORTS OF NOISE YOU'RE GONNA HAVE TO DEAL WITH UH IS IS IS HISS OR IMPULSIVE I WOULD SAY OR OR THAT WOULD BE A GOOD START NO ANYWAY SO WE OKAY SO WE'LL FINISH THIS CALL ROUTING STUFF WHAT DO YOU SAY ALL THI THIS IS OKAY WITH YOU RIGHT SO WE'LL K BECAUSE I THINK UH IT IT IT HAS NOT BEEN EVEN SUBMITTED OUTSIDE ALSO THE WORK WHAT JEAN YVES DID YET MM YEAH NOT DONE THAT YET TRIED UH YEAH HE STILL YEAH I THINK YEAH WITH A BETTER UH PHONEME RECOGNITION RATE DEFINITELY IT COULD UH IMPROVE ALSO THE THE CALL ROUTING PERFORMANCE IT WAS SHOWING THAT UM YOU HAVEN'T HEARD FROM HIM I TAKE IT EITHER NO OKAY
