OKAY WE START WAITING FOR PEOPLE COMING LATE AND UH I CAN SAY THIS BECAUSE IN THIS MOMENT YOU CANNOT ANSWER BECAUSE YOU DON'T HAVE THE MICROPHONE SO I CAN SAY WHATEVER AND YOU CANNOT REPLY SO YEAH YEAH IT'S OKAY U OH I HATE THESE THINGS VOILA OKAY SO UM WE CAN MAYBE GET A HEAD START UM HAVE YOU BEEN TALKING TO MATTHEW ABOUT WHAT YOU'VE BEEN DOING OR SO UH BASICALLY UH WELL FIRST WE TRIED TO UM EXPLAIN WHY IN THIS UH RESC UH N. BEST LIST RE SCORING UH FROM THE SLIDES TO ENHANCE THE SPEECH RECOGNITION ON THE MEETINGS DATA IS NOT WORKING SO UM UH THAT'S ONE THING AND UH SO WHAT WE DID WITH ALESSANDRO IS UH UM CH T UH PERFORMING SOME STATISTICAL TESTS TO SEE WHATEVER R IF THE IF THE WORDS UH THE THE APPEARANCE OF THE WORDS DURING THE MEETING IS UH IN INDEPENDENT OF THE AP APPEARANCES OF THE DIFFERENT SLIDES YEAH SO THE IN THE CASE IF IT IS DEPENDENT THAT WOULD MEAN THAT CERTAIN WORDS TEND TO APPEAR DURING CERTAIN SLIDES AND THAT THERE IS A CORRELATION AND UH THEN THERE WILL BE UH A REASON LIKE FOR BELIEVING THAT UH THIS WILL WORK YEAH AND IS AND THE R RESULT WAS NO BUT UH BU BUT THE QUESTION IS IF IS THAT RESULT NO BECAUSE IT'S NO OR IS IT ALSO JUST BECAUSE THERE'S NOT REALLY ENOUGH DATA TO BE SURE ABOUT ANYTHING IN MY OPINION IT IS NO BECAUSE OF THE NATURE OF THE LANGUAGE I MEAN INTUITIVELY OF COURSE YOU TEND TO USE MORE THE WORDS THAT ARE ON THE SLIDE BUT THE MASS OF THE WORDS ACTUALLY YOU USE ARE WORDS THAT ARE COMMON JUST THINK THAT FIFTY PERCENT OF THE WORDS ON AVERAGE WHATEVER CORPUS YOU TAKE ARE STOP WORDS ARTICLES ET CETERA SO IN TERMS OF RECOGNITION FIFTY PERCENT GOES AWAY OF THE REST UH REMAINING FIFTY PERCENT I MEAN ARE ALL WORDS THAT APPEAR ONE TWO THREE TIMES SO IN ANY CASE EVEN IF ACTUALLY AND THEY TEND TO BE UH RELATED OR A STATISTICALLY RELATED TO A SINGLE SLIDE IN ANY CASE IN TERMS OF UH RECOGNITION DO NOT HELP AT ALL OR HELP A VERY LITTLE YEAH YEAH YEAH THIS IS SO SORT OF A FEELING THAT WE HAD BUT HADN'T SHOWN I THINK I MEAN I IN UH FROM UH FROM AN APPLICATION POINT OF VIEW IT MIGHT BE INTERESTING TO MAKE SURE THAT YOUR VOCABULARY CONTAINS ALL THE WORDS ON THE SLIDES BUT FROM A RESEARCH PERSPECTIVE IT'S NOT INTERESTING YOU KNOW EVEN IF ACTUALLY I REMEMBER I JUST MADE SOME MEASURE UH SAYING OKAY L LET'S LOOK AT HOW MANY WORDS I DON'T HAVE IN THE DICTIONARY AND ARE IN THE SLIDES IT WAS TWO PERCENT WELL THIS IS H THIS IS HOW THE DICTIONARY'S CALCULATED IT CALCULATED SUCH THAT IF YOU DON'T HAVE THE WORD IT DOESN'T AFFECT TO A GREAT DEGREE THE THE THE WORD ERROR RATE SO MM-HMM BUT IN PRACTICAL TERMS IN TERMS OF RECOGNITION UH HERE WE WE WE HAVE TO BE CLEAR YEAH SURE YEP UH IT IS DIFFERENT IF YOU WANT TO HAVE OTHER TASKS WHERE THE ONLY WORDS THAT ALL ARE WORDS IN THAT CASE EVEN THE SLIGHT IMPROVEMENTS UH HE GETS AT THAT POINT THEY CAN MAKE THE DIFFERENCE BUT DOES THE RECOGNITION NO WELL THIS IS YEAH THAT'S YEAH YEAH BUT THAT'S THAT'S WHAT HAPPENS BASICALLY SO MATTHEW WE WERE UH YEAH IT'S UH WE WERE TALKING THAT WE DID SOME EXPERIMENTS TO SEE IF THE WORD DURING MEETING THE WORDS APPEAR INDEPENDENTLY OF THE SLIDES IN A SENSE THAT UH IF CERTAIN WORDS TEND TO APPEAR DURING CERTAIN SLIDES OR NO AND UH THE ANSWER IS UH NO AND UH SO WE DID A STATISTICAL TEST FOR THAT AND I WILL ADD ALSO THAT WE DID THAT ON THE UH W THE WORDS AFTER FILTERING THEM FROM THE REMOVING THE THE STOP WORDS YEAH SO UH SO UH BEC S BECAUSE YEAH WITH THE STOP WORDS OKAY TH THERE WOULD BE A REASON FOR UH IN INDEPENDENCE BECAUSE THERE IS UH SUCH A HUGE MESS OF THEM BUT UH EVEN UH AFTER REMOVING THEM UH THERE IT IT REMAINS UH INDEPENDENT AND ACTUALLY UH SO WHEN I WAS DOING THE RE SCORING EXPERIMENTS I WAS DOING THAT ON UH ONE MEETING THAT I SELECTED AS BEING LIKE THE BEST LOOKING ONE UH IT HA IT HAD THE M THE MOST UH SLIDES AND NOW I DID THE SAME UH ON UH THE OTHER MEETINGS WHICH WERE AVAILABLE WHERE WELL IT'S ONLY THREE MEETINGS BECAUSE WELL HERE THERE ARE FOUR OF THEM WHICH ARE FROM THE TEST SET UH FROM THE AMI RECOGNISER W BUT ONLY THREE OF THEM HAVE UH SLIDES SO IT'S TOTAL OF THREE MEETINGS AND FOR THE OTHERS THE TENDENCY AND I C 'CAUSE YOU KNOW I WAS WHEN I WAS DOING RE SCORING I WAS UH TAKING INTO ACCOUNT THE FOR ONE GIVEN SLIDE ALSO THE N NEIGHBOURING SLIDES AND AS I WAS IN INCREASING THE NUMBER OF SLIDES WHICH WERE AFFECTING THE THE UTTERANCE I WAS RE SCORING UM THE PERFORMANCE WAS IMPROVING SLI S UH SLIGHTLY VERY VERY LITTLE BUT UH WAIT WAIT IT'S GOING VERY FAST FOR ME ACTUALLY THING ACTUALLY IT'S VERY FAST SO WHA FIRST POINT THE FIRST THING YOU TOLD ME THAT YOU TOOK THE SLIDES AND YOU WAS AND YOU HAD A L BIG DICTIONARY AND YOU ARE SEEING UH WHAT WHAT ARE THE INSIDE THE SLIDE RIGHT UH WHAT THE 'CAUSE I FIRST STATEMENT I COULD NOT UNDERSTAND UH WHEN YOU SAID THE THE ST UH UH THE S UH THE W YEAH SO WE WHAT'S SO YEAH SO COULD YOU PLEASE TELL ME LITTLE BIT MORE IN DETAIL YEAH UH SO WE USED THE PEARSON UH CHI SQUARE UH TEST NO I WANT TO UNDERSTAND WHAT DID YOU MEAN BY THE WO UH THE TE UH THING LIKE SAYING THAT I TOOK A DICTIONARY AND THEN A WORD FROM THE SLIDE AND WHAT YOU ARE LOOKING FOR I COULD NOT UNDERSTAND CLEARLY CLEARLY THAT MM MM-HMM OKAY BUT DO HOW DO WHY DO YOU WANT CERTAIN WORDS LIKE WHA HOW DO YOU EXPECT THAT CERTAIN WORDS SO THE POINT IS YOU WANT TO VERIFY WHETHER YOU CAN IMPROVE THE RECOGNITION RATE BY USING AS AN INFORMATION THE WORDS THAT UH ARE CONTAIN IN THE SLIDES SO BASICALLY THE IDEA IS THAT UH IN THE MOMENT YOU ARE IN THE SLIDE SOMEWHERE YOUR LANGUAGE CHANGE ACCORDINGLY TO THE SLIDE SO THE FACT OF HAVING THAT INFORMATION SOMEWHERE CAN HELP YOU TO IMPROVE THE RECOGNITION BUT ACTUALLY IT'S NOT WHAT HAPPENS AND THIS DOES NOT HAPPEN FOR MANY REASON FIRST FOR EXAMPLE FIFTY PERCENT OF THE WORDS IN ANY KIND OF TEXT ARE STOP WORDS SO ARE EVERYWHERE YEAH AND THE REMAINING A APPEAR SO LITTLE THAT IN THE CASE CANNOT REALLY IMPROVE THAT MUCH MOST OF THE WORDS WE USE ACTUALLY WHATEVER WE TALK ABOUT ARE COMMON UH WORDS SO HOW TO VERIFY THIS
