Manner Of Articulation

Subjects were English-speaking adults with hearing impairment. Etiology of hearing loss did not enter into selection. Consonant errors were observed on speech discrimination test lists employing a closed-set response system. Fifteen subjects were employed for the first list and 20 each for the remaining four lists, with an occasional subject serving in more than one group. Confusions between unvoiced and voiced consonants rarely occurred; the /r/ and /l/ were seldom confused with other phonemes; and nasals were seldom confused with non-nasals. Discrimination difficulty was related to both place and manner of articulation.

Vowel Discrimination

Vowel discrimination ability was observed in two groups of 20 hearing-impaired subjects each. Each group listened to a different list of closed-set test items specifically designed for the study. A surprisingly low number of errors occurred, suggesting that vowel items in general lack the efficiency required for speech discrimination testing using a closed-set response system. Among the most difficult phonemes to discriminate clearly were /ɔ I /, /ɔ/, /au/, /ε/, /o/, and /α/. The phonemes most frequently substituted in error were adjacent to the stimulus phoneme on the Formant 1 versus Formant 2 vowel charts. The /u/ was the most frequent substitution for several vowels.

Central Auditory Function

Audiological data are presented for an 11-year-old aphasic girl with confirmed left-hemisphere damage. Pure-tone audiometry, impedance measurement, and speech discrimination testing were completed. Discrimination testing included presentation of the Word Intelligibility by Picture Identification (WIPI) test at 0 and 60% time compression. Results indicated significantly poorer speech discrimination in the ear contralateral to the site of lesion at 60% time compression. This case study supports the use of time-compressed speech discrimination testing in the assessment of central auditory function of children and as a diagnostic tool for determination of site of lesion.

Multiple Choice Items

In the course of developing multiple-choice items for speech discrimination testing, phonemic errors were observed as they relate to pure-tone configurations and to certain types of hearing impairment. For the phonemes involved, the following observations were made: (1) The /s, ∫, t∫, d 3 / and the initial /t/ and /θ/ were easily identified by patients with flat pure-tone configurations, but were difficult for patients with sharply falling slopes, 500 to 4000 Hz. (2) Identification of the /s/ and the initial /t/ and /θ/ was highly dependent upon energy in the frequency range above 2000 Hz, whereas identification of the /∫, t∫, d 3 / was highly dependent upon the range between 1000 and 2000 Hz. (3) Over all the items testing a given stimulus phoneme, the total number of phonemes employed as alternate responses ranged from three to eight, averaging five. The actual erroneous responses for any given stimulus phoneme, however, were usually limited to two or three phonemes, and these were generally the same regardless of pure-tone configuration. (4) Although the error-response phonemes were usually the same as the stimulus phoneme in manner of production, some error phonemes were produced in a different manner, but in the same place, as the stimulus phoneme. Probability of error for individual phonemes seemed to be more closely related to pure-tone configurations than to kinds of hearing impairment.
