Test usually carried out in either ear
Monaural
Test usually carried out in both ears simultaneously
Binaural
What are the two kinds of speech thresholds
Speech-detection threshold (SDT)
Speech-recognition threshold (SRT)
Defined as the lowest level, in decibels, at which a subject can barely detect the presence of speech and identify it as speech
Speech-detection threshold (SDT)
Defined as the lowest hearing level at which speech can barely be understood
Speech-recognition threshold (SRT)
For a number of reasons, the ____ has become more popular with audiologist than the ___ is thus preferred speech-threshold test
SRT; SDT
Today most SRTs are obtained with the use of ____, often called spondees
Spondaic words
A word with two syllables, both pronounced with equal stress and effort
Spondee
On some prerecorded spondee lists, a _____ precedes each word, for example, “say the word…..,” folllowed by the stimulus word
Carrier phrase
the ___ is usually defined as the lowest hearing level at which 50 percent of a list of spondaic words is correctly identified
SRT
____ are especially useful in testing young children who will “play a game” with words but not with tones
bone-conducted SRTs
The ____ is always higher (requires greater intensity) than the ___
SRT; SDT
Although some of these produces have been quite elegant, most audiologist have agreed that the SRT can be predicated by finding the average of the lowest two thresholds at 500, 1000, and 2000 Hz
True
Unlike the ____, which is a decibel measurement of the softest level that can be heard, the ____ is a percentage measure that qualities how clearly speech is heard
Speech recognition threshold; speech recognition score
Means that a test is able to reveal similar scores on subsequent administrations (test-retest reliability) and that different forms of the same test result in equivalent scores
Reliability
The validity of any speech-recognition test relates to the following:
- How well it measures what it is supposed to measure (a person’s difficulties in understanding speech)
- How favorably a test compares with other similar measures
- How the test stands up to alterations of the signal (such as by distortion or presentation with noise) that are known to affect other speech tests in specific ways
___were designed to reduce word-recognition test time without sacrificing validity
Short isophonemic word lists
The test used with these lists is designed to measure the word-recognition scores of patients with high-frequency hearing losses who are known to have special difficulties in understanding speech
High frequency emphasis lists
Developed two lists, each with 25 nonsense syllables. Every item contains a two-syllable utterance, with each syllable produced by a consonant, followed by a vowel (CVCV)
Nonsense-syllable lists
Patients are supplied with a list of six rhyming words and select the one they think they have heard. Fifty sets of items are presented to the patient, along with a noise in the test ear. Half of the word sets vary only on the initial phoneme, and the other half differ in the final phoneme
Modified rhyme test
A closed-response test designed to be sensible to the discrimination problems of patients with high-frequency hearing losses. In this test, one hindered monosyllabic words are arranged in two scramblings to produce two test lists. The patient, selecting from four possibilities, marks a score sheet next to the selected word.
California consonant test
Developed by Wilson and Antablin to test the word recognition of adults who could not produce verbal responses and had difficulty in selecting items from a printed worksheet
Picture identification task (PIT)
Children is presented with a series of cards, each of which contains six pictures. Four of the six pictures are possibilities as the stimulus item on a given test, and the other two pictures on each card (which are never tested) act as foiled to decrease the probability of a correct guess. Children indicate which picture corresponds to the word they believe they have heard
Word intelligibility by picture identification (WIPI) test
Child is presented with a series of four picture sets, including 65 items with 50 words scored on the tests
Northwestern university children’s perception of speech (NUCHIPS) test
