ABSTRACT
Objective To study the characteristics and difference of speech rate in monologue and reading in normal adults .Methods Through the acquisition of spontaneous speech and reading from 30 normal adults ,the syl‐lables per minute (SPM ) and the words per minute (WPM )were separately calculated .The monologue materials in‐clude ten topics :self introduction hobby ,hometown and so on;the reading material was the stars in the sky written by Ba Jin .We also analyzed whether there was a significant difference in genders and types of expression for speech rates .Results With the expression of monologue :SPM (male)=226 .13 ± 25 .97 ,SPM (female)=198 .73 ± 40 .With the expression of reading :SPM (male)= 208 .93 .13 ± 29 .35 ,SPM (female)= 220 .53 .± 26 .52 ,WPM (male)=104 .67 ± 13 .43 ,WPM (female)=111 .80 ± 12 .73 .Pearson correlation coefficient of SPM and WPM had reached 0 .926(r=0 .926) in the spontaneous speech and 0 .969 (r=0 .969) in reading .There were no significant differences in both genders (P=0 .42) and types of expression(P=0 .72) .The interaction effect of genders and types of ex‐pression was significant (P=0 .006) .For females ,the rate of reading was significantly higher than monologue (P=0 .025);for monologue ,there was a significant difference between males and females(P=0 .035) .The male was higher than the female in the speed of monologue .Conclusion The statistics revealed a high correlation between SPM and WPM .Genders and types of expression did not play an important role on the speech rate .The interactioneffect of gender and type of expression was significantly high (P=0 .006) .
ABSTRACT
Objective By analyzing the graph features of fundamental frequency at different rates of/i/with continuously variable pitch and loundness made by normal adults,we could explore that the rate and gender have some impact on the graph to lay the foundation of regulating the clinical maximum counting ability.Methods Nor-mal adults of 51 (25 males,26 females were included).After each deep breathing,the subjects respectively took sustained speech/i/ with continuously variable pitch and lounolness twice at different rates of fast,medium and slow speed.Some parameters were measured byDoctor Speechat different rates of the tone/i/:Total time(T), Mean time standard deviation (MTSD),Mean wave crest (MWC),Mean wave trough (MWT),Mean frequency range (MFR),Mean frequency range standard deviation (MFRSD),comparing the speed having some effect on those above parameters with gender.ResuIts ①With the increasing rate of speech,the tone/i/of T (P0.05 ).②The tone /i/ of T (P>0.05 )were not effected by gender,female's MWT (P<0.001),MWC (P<0.001),MFR (P<0.001),MFRSD (P<0.01)were obviously higher than male's,while female's MTSD were significantly larger than male's (P<0.01).ConcIusion We should consider the impact of rate of speech and gender in clinical tests and values of MCA.The maximum counting capacity can be respectively tested at three different rates of speech for each subject,but only are the tone/i/of fun-damental frequency graphs with MWT,MWC,MFR,and MFRSD in normal range with corresponding speed and gender,can we get the value or can the value be valid.
ABSTRACT
Objective To investigate the effects of Mandarin speech rate on Mandarin acceptable noise level test in normal hearing adults.Methods Using the national Putonghua proficiency test material to produce 0.8 times,1.0 times and 1.2 times speed rate of ANL test materials.ANL tests were measured for 58 normal hearing a-dults using different peed matetrials.For each case,the most comfortable loudness(MCL)and background noise lev-el(BNL)were found.The ANL was then computed by subtracting the mean BNL from MCL.ResuIts Statistic anal-ysis indicated that there were no significant differences of the ANL(P>0.05)among the differenct speed materials, there were no correlation between MCL-ANL (P>0.05),negatively correlation between BNL-ANL(P<0.05)a-mong the differenct speed materials.ConcIusion Mandarin speech speed does not effect ANL test,the more the in-dividual’s ability to accept the background noise,the smaller the value of ANL.
