I MEAN THIS IS SOMETHING THAT HAS BEEN MEASURED ET CETERA BUT STILL IS A BIT QUALITATIVE TO HAVE A QUANTITATIVE MEASURE MM-HMM WE SIMPLY DID UH A MEASURE OF STATISTICAL INDEPENDENCE BETWEEN THE WORDS IN GENERAL SO NOT SOME WORDS THE WORDS IN GENERAL OTHERWISE YOU CAN SEE THAT IF A WORDS APPEAR ONCE BASICALLY IT IS ONE HUNDRED PERCENT RELATED TO ONE SLIDE HUH BUT YOU HAVE TO I IF YOU WANT TO CONSIDER IN TERMS OF RECOGNITION HAVE TO MAKE IT OVERALL I MEAN WHAT IS IMPORTANT IS NOT THE WORD THAT APPEAR ONCE IT'S THE WORD THAT APPEAR IF UH I EXACTLY IF IF THERE IS ONE WORD THAT APPEAR ONCE ALL OVER THE MEETING IT APPEARS IN CORRESPONDENCE OF ONE SLIDE THEN OF COURSE IT SEEMS TO BE VERY RELATED BUT VERY FEW WORDS UH THEY REPRESENT A VERY LITTLE PART OF THE WORD MASS MM SO WE SIMPLY USED A VERY OLD TEST STATISTICAL TEST THAT BASICALLY MEASURE THE HYPOTHESIS THAT SOME WAY THE PROBABILITY OF HAVING ONE WORD IN CORRESPONDENCE OF A CERTAIN SLIDE IS SIMPLY THE PRODUCT OF THE PROBABILITY OF THE WORD FOR THE PROBABILITY OF THE THAT'S IT SO THAT'S WHAT WE DID BUT IS IN GENERAL THE LANGUAGE AND NOT CERTAIN WORDS BECAUSE CERTAIN WORDS FOR SURE HAVE A STRONG DEPENDENCY ON THE SLIDES BUT THERE ARE L FEW YEAH HMM NOW I'M UH OKAY I'M INTO THE LOOP MM-HMM MM-HMM UH SO I WAS R OBSERVING AN IMPROVEMENT AS I WAS INCREASING UM LIKE THE UM THE CONTEXT YEAH UH OR UH WHERE OKAY SO THERE WAS UH THE IMPROVEMENT WAS ALSO INCREASING AS I WAS INCREASING THE CONTEXT WHILE ON THE OTHER MEETINGS IT'S UM IT'S IT'S IT'S REALLY FLUCTUATING AND UH I IT IT UH IT LOOKS MORE LIKE UM UH PS UH WELL WHAT'S THE WORD FOR THAT STATISTICAL UM UM FLUCTUATION SO UH YEAH ELSE INTERPOLATE EXTRAPOLATE YEAH YEAH MM-HMM UH YEAH BUT SO I MEAN I GUESS THAT'S NOT A SURPRISING RESULT THEN THE UM IT IS NOT IN TERMS I MEAN FOR ME FOR EXAMPLE IT WAS NOT IN THE SENSE THAT UH AFTER WORKING A LITTLE BIT ON LANGUAGE YOU REALISE THAT THIS KIND OF THING DO NOT HELP SIMPLY BECAUSE MOST OF THE WORDS UH HAVE NOTHING TO DO SPECIFICALLY WITH THE SUBJECT YOU USE UH MOST OF THE WORDS WE USE UH THAT'S STRANGE BUT ARE SIMPLY NECESSARY TO BUILD A SENTENCE THERE ARE VERY FEW UH CONTENT UH WORDS BUT IT IS TRUE THAT INTUITIVELY UH AS WE ARE DRIVEN IN OUR ATTENTION UH I MEAN IN IN OUR UNDERSTANDING WE'RE PRETTY MUCH DRIVEN BY ATTENTION THAT WE TEND TO SPOT ONLY THOSE WORDS EXACTLY AND IN SOME SENSE INTUITIVELY IT SEEMS THAT IT CAN HAPPEN I MEAN THIS IS NOT THE FIRST ATTEMPT TO DO THINGS LIKE THIS AND IT NEVER WORKS ACTUALLY I IN TERMS OF RECOGNITION FOR OTHER TASK IT CAN BE UH IT CAN BE UH HELPFUL SO YOU MEA SO UH YOU MEAN TO SAY THAT UM LIKE WHEN ONE CASE YOU WERE SAYING THAT IF YOU INCLUDE THE CONTEXT AND ALL THOSE THING IT HELPS IN YOUR A. S. R. IMPROVEMENT BUT IT DOESN'T WHICH MORE SUBJECTIVE I THINK THIS WHOLE WELL I MEAN UH IT JUST COMES DOWN TO THE TO THE MERE FACT THAT WORD ERROR RATE IS JUST TAKE THE WORDS HOW MANY OF THEM DID YOU GET RIGHT TAKE PLUS OR MINUS TWO OR THREE OR FIVE OR TEN WORDS DOESN'T REALLY MAKE ANY DIFFERENCE SO YEAH EVEN IF THOSE WORDS AT THE END OF THE DAY WOULD BE QUITE IMPORTANT IN ANY SORT OF SEARCH OF THE TRANSCRIPT BUT AT THE END OF THE DAY WHY WOULDN'T YOU JUST USE THE SLIDES TO SEARCH THE TRANSCRIPT I IF YOU HAVE TH SLIDES THEN YEAH SO THAT'S WHY UM UH IF WE LOOK ON THE RELATIONSHIP THAT UH EXISTS BETWEEN THE SPEECH AND THE SLIDES UH THE TASK OF IMPROVING THE RECOGNITION UH THE OVERALL UM SP UH SPEECH RECOGNITION USING THE SLIDES UH SEEMS TO BE UH UH NOT VERY UH UM GOOD I MEAN UM WE CANNOT EXPECT MUCH FROM FROM IT HAVE YOU HAVE YOU BEEN THINKING ABOUT WHAT YOU WOULD LIKE TO TO DO IN IN IN PLACE OF THIS OR OR OR LEADING ON FROM THIS GIVEN WHAT YOU'VE LEARNT MM WELL FOR NOW THE UH MOST EFFORT WAS UH ON UH UM SHOWING WHY I IT'S I IT'S IT WILL NOT WORK ESPECIALLY THOSE EXPERIMENTS AND THESE UH STATISTICAL TESTS BUT UH WE W WERE THINKING FOR EXAMPLE OF A TASK LIKE UM TRYING TO UH SEE IF UH WHERE A SPEAKER IS TALKING I MEAN IF THE SPEECH IS ACTUALLY CORRELATED WITH THE SLIDES UH WHERE THE SLIDES UH WHICH HAPPEN DURING THE NOT CORRELATED BUT IF THE BE CAREFUL CORRELATE IS A DANGEROUS WORD IN STATISTIC IT SEEMS TO BE THE OPPOSITE AS BEFORE UH WELL IF THE UM ASSOCIATED IF THE SPEAKER IS ACTUALLY TALKING ABOUT WHAT IS IN THE SLIDES OR NOT OKAY OR ROUGHLY BASICALLY UH ONE THING IT CAN'T BE DONE AND AND HERE UH ON THE CONTRARY FOR EXAMPLE THE FEW WORDS THAT ARE MM HOW MAY I SAY IT RECOGNIZED MORE CAN REALLY MAKE THE DIFFERENCE IT ISN'T THE CASE IF YOU WANT TO SEE IF UH I MEAN WHAT IF SEEN IN THE MEETING AND THAT OKAY THERE ARE PRESENTATION THEN YEAH STILL THE SLIDE IS THERE BUT ACTUALLY THE PEOPLE TALK ABOUT OTHER THINGS OR NOT REALLY OTHER THINGS BUT THE SLIDE IS NO LONGER UH A SUPPORT FOR THE DISCUSSION HUH THERE ARE MOMENT THAT ACTUALLY THIS IS THE SUPPORT BECAUSE THE PEOPLE DESCRIBE ET CETERA AND THERE ARE MOMENT WHERE IT IS NOT IS A JUST A BACKGROUND UH THING AND WE ROUGH ESTIMATED VERY QUICKLY BUT IT WAS ONE THIRD OF THE TIME AT LEAST IN IN THE MEETING WE HAVE SEEN THE SLIDE WERE JUST THERE I MEAN BUT THEY WERE NO LONGER USE AS A SUPPORT IT WAS A DISCUSSION RATHER BETWEEN PEOPLE SO IN THAT CASE THE PRESENCE OR THE ABSENCE AND ESPECIALLY THE FREQUENCE WITH WHICH YOU OBSERVE THE WORDS THAT ARE ON THE SLIDES CAN BE AN EXCELLENT UH UH CLUE HUH INDICATION A CLEAR INDICATION WHETHER ACTUALLY DOES IT SUPPORT OF THE DISCUSSION OR NOT UH IT CAN BE THIS IT CAN BE INTERPRETED AS A KIND OF FOCUS OF INTEREST IT CAN BE SIMPLY INTERPRETED IN THE SENSE OF SAYING UH OKAY I MEAN YOU HAVE THIS CHANNEL OPEN THERE DO I HAVE TO P TAKEN INTO ACCOUNT OR NOT HMM OR ALSO IN TERMS OF ACTION YEAH UH WHEN YOU SEE THAT S THE DISCUSSION IS COMPLETELY M DISCONNECTED WITH RESPECT TO THIS SOME WAY UH IT MEANS THAT IT'S HAPPEN IN SOMETHING DIFFERENT THAN BEFORE SO I MEAN IT'S A KIND OF FEATURE THAT IN MY OPINION CAN BE EASY TO DETECT IT AND UM THAT CAN YEAH UH F CAN BE INTERESTING TO DO RELATIVELY EASY TO DO
