Reception of acoustic speech signals as a function of sensation levels by hearing-impaired children

This paper is a review of a study to determine the sensation level at which the best discrimination and recognition occurs for severely and profoundly deaf children and the effect of distortion (peak clipping) has on the child's ability to recognize speech.

Monaural and binaural loudness summation of speech

This paper reviews a study to determine optimum hearing aid settings based on loudness.

The southern sotho speech identification/discrimination test construction

This paper contains a speech discrimination test in Southern Sotho language (an African language spoken in Southern Africa).

Perception of speech through a 500 Hz low-pass filter: sensory aids and communication strategies

This paper reviews a study to investigate how a hearing impaired person can learn to discriminate speech distorted by a low pass filter in a sensory aid.

Effect of amplification bandwidth on speech intelligibility

This paper was a study to examine the effect of bandlimiting on speech intelligibility.

The effect of talker age and gender on speech perception of pediatric cochlear implant users

Most clinically-employed speech materials for testing hearing impaired individuals are recordings made by adult male talkers. The author examined the possible effect of talker age and gender on the speech perception of children through the use of 1) two speech perception tests, each with four talker types (adult males, adult females, 10-12 year olds, 5-7 year olds), and 2) two groups of pediatric listeners: normal-hearing (NH) and cochlear implant users (CI).

Effect of unilateral hearing loss on the speech-evoked auditory brainstem response in the presence of noise

Speech-evoked auditory brainstem responses (ABRs) were acquired in quiet and in the presence of noise at two study sessions to investigate 1) test-retest variability and 2) subcortical representation of speech stimuli. Participants were adults with normal hearing in both ears who listened monaurally and adults with unilateral deafness. Results indicate consistency in responses across sessions and several differences between hearing groups for magnitudes of discrete components.

Comparing speech assessments: The usefulness of the DEAP as compared to the GFTA-2

This study seeks to evaluate whether the DEAP, a new speech assessment that assesses vowels in addition to consonants, is as effective with children who are deaf and hard of hearing as an older, more established speech assessment, the GFTA-2.
