Restoration Method

Prosthesis airway resistance calculations were completed for five Blom-Singer prostheses and esophageal source airway resistance estimated were made of five laryngectomized patients using the Singer-Blom voice restoration method. Airway resistance of the Blom-Singer prostheses ranged from 46 to 121 cmH 2 O/LPS, while source airways resistance in these subjects ranged from about 155 to 270 cmH 2 O/LPS. These results revealed that the opposition of the voicing sources used in esophageal speech production to airflow through them is substantial and larger than that established for the normal, laryngeal source. Findings are interpreted to highlight major advantages the Singer-Blom (1980) method of speech/voice restoration has over esophageal speech/voice produced on a conventional basis and to reveal specific reasons for the failure of may laryngectomized patients to develop consistent voice and functionally serviceable speech.

Air Supply

The duration of a large number of representative vowels produced by 10 esophageal and nine normal speakers were measured. Overall vowel durations of esophageal speakers were consistently longer than those of normal speakers, indicating that esophageal speakers do not compensate for their striking diminution in air supply for speech by decreasing vowel duration. The differences in the vowel duration characteristics between normal and esophageal speakers were observed to vary systematically as a function of the voicing features of their consonant environments. Specifically, the durations of vowels of esophageal speakers spoken within voiceless consonant environments were consistently longer than those spoken in similar contexts by normal speakers. There were no significant differences between the average durations of vowels spoken by normal and esophageal speakers within voiced consonant environments. The observation that the durations of vowels produced by esophageal speakers differed significantly as a function of the voicing features of their consonant context was interpreted to support the belief that inherent, rule-governed durational features of English are retained following laryngeal amputation.

Monosyllabic Words

Levels of isolated vowels and the influence of consonant environment on vowel level were determined for three esophageal speakers and three normal speakers. Twenty lists of isolated vowels and diphthongs and 576 monosyllabic words were used as the stimuli. The results revealed that esophageal speakers had an 11-dB reduction in SPL compared to normal speakers. The greatest level was observed on the vowels /i/ and /u/. Differences between normal and esophageal speakers are discussed in terms of absolute level and phonetic environment.
