Q

The validity of any speech-recognition test relates to the following:

A
  1. How well it measures what it is supposed to measure (a person’s difficulties in understanding speech)
  2. How favorably a test compares with other similar measures
  3. 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

Q

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)

A

Nonsense-syllable lists

20
Q

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

A

Modified rhyme test

21
Q

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.

A

California consonant test

22
Q

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

A

Picture identification task (PIT)

23
Q

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

A

Word intelligibility by picture identification (WIPI) test

24
Q

Child is presented with a series of four picture sets, including 65 items with 50 words scored on the tests

A

Northwestern university children’s perception of speech (NUCHIPS) test

25
Q

Involves a set of ten synthetic sentences. To decrease the effects of guessing, each sentence contains 7 words, with a noun, predicate, object, and so on, but carries no meaning. All words were selected from Thorndike’s list of the 1000 most familiar words.

A

Testing speech recognition with sentences

26
Q

Fifty key words are contained within ten sets of ten sentences each. The percentage of correctly identify key words determines the score

A

Central institute for the deaf (CID) Everyday sentence test

27
Q

Many audiologists feel that speech-recognition tests carried out in quiet do not taxa patients’ speech-recognition abilities sufficiently to reflect the kinds of communication problems that are experienced in daily life

A

True

28
Q

A test made up of eight lists of 50 sentences each; only the last word in each sentence is the test item, resulting in 200 test words. The test items are recorded on one channel of a two—channel CD, and a voice babble is recorded on the second channel. In this way, the two hearing-level dials of an audiometer can control the ratio of the intensities of the two signals

A

Speech perception in noise (SPIN) test

29
Q

Designed to obtain an estimate of a patients experienced difficulty hearing in noise that is representative of the patients performance in the real world. The test is comprised of six sentences presented in the presence of a four0talker babble noise, with five key words per sentence. The sentences are presented at five prerecorded signal-to-noise ratio encompassing a range from normal to severely impaired performance in noise

A

QuickSIN (speech in noise) test

30
Q

Comprised of eight sets of six passages, the patient listens to each passage, given one sentence at a time, and is instructed to retreat as much of each sentence as he or she understands. Each passage contains 25 keywords that are used for scoring, with intelligibility scores based on the number of key words repeated correctly

A

Connected speech test (CST)

31
Q

Measures the listeners ability to hear sentences in quiet and in noise in the sound field

A

Hearing in noise test (HINT)

32
Q

For the more commonly used speech-recognition tests, the results are recorded on the ____ in terms of the percentage of correctly identified words

A

Audiometer worksheet

33
Q

When administering speech-recognition tests, audiologists must decide on:

A
  1. The method of delivery of the speech stimuli (prerecorded material is recommended over monitored live-voice)
  2. The type of materials to be used
  3. The method of response
  4. The intensity at which the test will be performed
  5. Whether more than one level of testing is desired
  6. Whether a competing signal is desired in the test ear (or loudspeaker) to increase the difficulty of the test and, if so, the intensity of the competition
  7. Whether masking of the no test ear is necessary and, if so, the amount and type of noise to use
34
Q

Instructions to patients should be delivered orally, even if printed instructions have been read prior to the test

A

True

35
Q

The presentation level of the stimuli should be properly controlled and monitored on the VU meter of the audiometer

A

True

36
Q

The audiologists should be seated in front of the microphone and should speak directly onto its diaphragm

A

True

37
Q

During testing patients may respond by-

A

Repeating the stimulus word, writing down their responses on a form (with 50 or 25 numbered spaces for standard word lists), circling or marking through the correct answer on a closed-message set, or pointing to a picture or object

38
Q

Many of the word lists currently used in speech-recognition testing were developed during ____ to test the efficiency with which electronic communications systems could transmit speech

A

World war 2

39
Q

Regardless of whether speech-recognition testing is done at a set sensation level (above the SRT) for each ear or a preset intensity that os the same in both ears, the amount of the audible signal in the ear varies depending on the degree of hearing loss and its configuration

A

True

40
Q

Although the test-retest reliability of word tests is good for patients with normal hearing and conductive hearing losses, this consistency sometimes fails for patients with primarily sensory/neural impairments

A

True

41
Q

Many patients perform considerably better on speech-recognition tests than they do in daily conversation, and other not nearly as well.

A

True

42
Q

Speech-recognition tests may be helpful in diagnosis, but they are far from perfect for predicting real-world communication performance

A

True

43
Q

In cases of sever mixed hearing loss, a patient’s best possible speech-recognition score may not be attainable because of the severity of the air-conduction hearing loss

A

True

44
Q

It is possible to estimate a persons speech-recognition ability based on the amount of the speech signal that is audible with a given hearing loss

A

Audibility index or speech intelligibility index

45
Q

___ provides a quick visual depiction of the audibility of speech with a given hearing loss

A

Speech sound audiogram

46
Q

Some audiologists gain useful information from determining the hearing level at which speech is most comfortably loud for their patients

A

Most comfortable loudness (MCL)

47
Q

Most people with normal hearing find speech comfortable at ___ above threshold

A

44 to 55 dB
