INTRODUCTION Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution. OBJECTIVE To characterize the temporal processing and long-latency auditory evoked potential in stutterers and to compare them with non-stutterers. METHODS The study included...

This study was designed to examine the role of duration in vowel perception by testing listeners on the identification of CVC syllables generated at different durations. Test signals consisted of synthesized versions of 300 utterances selected from a large, multitalker database of /hVd/ syllables [Hillenbrand et al., J. Acoust. Soc. Am. 97, 3099-3111 (1995)]. Four versions of each utterance wer...

designing and scheduling of drip irrigation systems are often done without enough information about water distribution in the soil. due to tillage operations and crop production practices, agricultural soils can be considered as two layered soils with different bulk densities. the top soil layer has a lighter texture than the sub soil layer. in this research, the development of the wetting fron...

Automated perimetry, a vision test that is likely performed thousands of times a day within the Unites States alone, has been conducted largely unchanged for several decades. It is also true that many of the fundamental parameters of this form of testing were adopted wholesale from manual kinetic perimetry. Research is now emerging, which suggests that many aspects of automated perimetry, from ...
