The present study was performed to investigate and discuss the aerodynamic characteristics of whispered and normal speech during reading paragraph tasks. 39 normal females(18-23 yrs.) read 'Autumn' paragraph with whispered and normal phonation. Their readings were recorded and analyzed by 'Running Speech' in Phonatory Aerodynamic System(PAS) instrument. As results, during whispered speech, the total duration was longer and the numbers of inspiration were more frequently shown than normal speech. The Peak expiratory and inspiratory rate were higher in normal speech, but the expiratory and inspiratory volume were higher in whispered speech. By correlation analysis, both whispered and normal speech showed significantly high correlation between total duration and expiratory/inspiratory airflow duration; numbers of inspiration and inspiratory airflow duration; expiratory and inspiratory volume. These results show that whispered speech needs more respiratory effort but shows poorer aerodynamic efficacy during phonation than normal speech.

The performance of the speech recognition engine is one of the most critical elements of the in-vehicle speech recognition interface. The objective of this paper is to develop an automated platform for running performance tests on the in-vehicle speech recognition engine. The developed platform comprise of main program, agent program, database management module, and statistical analysis module. A simulation environment for performance tests which mimics the real driving situations was constructed, and it was tested by applying pre-recorded driving noises and a speaker's voice as inputs. As a result, the validity of the results from the speech recognition tests was proved. The users will be able to perform the performance tests for the in-vehicle speech recognition engine effectively through the proposed platform.

The present study was performed to investigate the characteristics of breath groups while reading paragraph in normal adults and adult patients with voice disorders. 10 normal females(avr. 20.6 yrs.), 10 young voice disorder females(avr. 33.5 yrs., P1 group), and 10 old voice disorder females(avr. 56.3 yrs., P2 group) read a paragraph of 210 syllables. By using the 'Running Speech' program of the Phonatory Aerodynamic System(PAS), total duration, numbers of breath groups, duration per breath group, and numbers of syllables per breath group were measured, and their correlations with aerodynamic measurement results of reading were analyzed. As a result, in total duration, numbers of breath groups, normals scored highest and P2 group speakers, lowest. Normals showed the longest duration per breath group which was not significant. P2 group speakers showed the highest numbers of syllables per breath group. Correlation analysis showed significantly high correlation scores of total duration and expiratory airflow; numbers of breath groups and inspiratory volume.

The purposes of this study are to analyze the effectiveness of public library reading programs for children in qualitative way and to apply the outcomes to identify areas to measure the success of library reading programs. Interviews were conducted with children who participated in '2013 Reading Books with Libraries' program and adults who were in charge of managing the program. Observations on the program were also conducted. The findings indicate that children who participated in '2013 Reading Books with Libraries' program positively changed in various aspects. Selected areas to measure the success of library reading programs include: reading behavior; attitude to books; awareness of libraries and librarians; participation of library reading programs; the ability to read aloud; the ability to comprehend stories by listening; aggression; the ability to express one's own feelings; speech ability; concentration power; and undiscovered potential. The elements that affect the success or failure of library reading programs include: librarian's enthusiasm on running the reading program; environmental condition of the community child care center; age differences between child participants; running style of the instructor's program; selection of books; child participants' reading abilities and interests in reading; available time for free voluntary reading.
