Inter-comparisons of articulation tests on normal and hard-of-hearing listeners

This paper discusses a study undertaken to test various speech discrimination tests.

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).

The effects of hearing aid gain on speech perception and the articulation index

This paper discusses a study to determine if changes in aided articulation indices predict changes in aided speech perception ability.

The intelligibility of different kinds of test material used in speech audiometry

This paper discusses several tests used to measure speech intelligibility and speech discrimination.

A comparative study of two methods of measuring loss of capacity to hear speech

This paper discusses a study to compare two tests of loss of capacity to hear speech.

Correlation of the articulation index to the MTS test under different listening conditions

This paper reviews a study to determine the relation between the aided articulation index and the aided speech recognition scores obtained with the Monosyllable, Trochee and Spondee (MTS) Test, when administered to hearing-impaired children.

Word level speech perception under four levels of simulated profound hearing loss

This paper discusses a study to determine average performance on word discrimination tests using the CID Early Speech Perception Test (ESP).

The effect of talker age and gender on speech perception of pediatric hearing aid users

Even though pediatric hearing aid (HA) users listen most often to female talkers, clinically-used speech tests primarily consist of adult male talkers' speech. Potential effects of age and/or gender of the talker on speech perception of pediatric HA users were examined using two speech tests, hVd-vowel identification and CNC word recognition, and using speech materials spoken by four talker types (adult males, adult females, 10-12 year old girls, and 5-7 year old girls). For the nine pediatric HA users tested, word scores for the male talker's speech were higher than those for the female talkers, indicating that talker type can affect word recognition scores and that clinical tests may over-estimate everyday speech communication abilities of pediatric HA users.
