Maximum Acceptable Oral Reading Speed For Voice Input Systems, Nirari M. Oda
Maximum Acceptable Oral Reading Speed For Voice Input Systems, Nirari M. Oda
Masters Theses
The objective of this thesis was to study the effect of vocal duration period and background noise on psychophysical oral reading speed. Ten healthy white males (21-28 years old) were used as subjects. Experiment one was designed to determine Maximum Acceptable Oral Reading Speed (MAORS) for an 8-hour period using psychophysical methodology. Results indicate that 114 words/min was an acceptable oral reading rate for an 8-hour day. Furthermore, 2 hours and 20 minutes is an acceptable testing period ( equivalent to the 8-hour day). Acoustical and physiological variables support these findings. Experiment two was designed to study the effect of …

The hydromount mechanism is studied. It was determined that the dynamic characteristics of the hydromounts are related to the rubber static stiffness, rubber damping coefficient, volumetric stiffness, and effectiveness of the oscillating fluid in the inertia track. At high frequencies the motion of the fluid in the inertia track diminishes so that its effect is negligible and may be ignored. It is also concluded that the rubber damping has a minimal effect on the hydromount dynamic properties and may be neglected. The maximum loss angle, which corresponds to the maximum damping coefficient of the hydromount, occurs near the inertia track …
