Table 1.
Characteristics and average sentence intelligibility test (SIT) scores are reported for participants with MS who were classified as being either high or low functioning according to neuropsychological tests.
| Participant code | Function level | Disease course | Deviant perceptual characteristics of speech | SIT (%) |
|---|---|---|---|---|
| MSF3 | High | RR | – | 98 |
| MSF5 | High | RR | – | 97 |
| MSF22 | High | SP | Harsh/hoarse voice, intensity decay, variable rate, imprecise consonants | 96 |
| MSF23 | High | SP | – | 97 |
| MSF33 | High | SP | – | 99 |
| MSM1 | High | RR | – | 97 |
| MSM5 | High | RR | – | 97 |
| MSM9 | High | SP | Slow rate, imprecise consonants | 93 |
| MSM17 | High | SP | – | 98 |
| MSM23 | High | RR | – | 96 |
| MSF10 | Low | SP | Strained voice, variable rate, imprecise consonants | 94 |
| MSF20 | Low | SP | – | 96 |
| MSF25 | Low | RR | Harsh/hoarse voice, excess and equal stress, slow and variable rate | 97 |
| MSF30 | Low | SP | Breathy voice, slow rate, imprecise consonants, excess and equal stress | 96 |
| MSF32 | Low | RR | Harsh/hoarse voice, slow rate, imprecise consonants, excess and equal stress | 96 |
| MSM7 | Low | RR | Harsh voice, imprecise consonants, slow and variable rate | 96 |
| MSM11 | Low | SP | – | 98 |
| MSM13 | Low | SP | Slow rate, reduced loudness | 98 |
| MSM14 | Low | RR | Harsh/strained voice, imprecise consonants, slow rate, excess and equal stress | 94 |
| MSM16 | Low | SP | Imprecise consonants, slow rate, excess and equal stress | 95 |
Note. SIT scores reflect the combined judgments of three speech-language pathologists. Participant code: multiple sclerosis (MS), female (F) and male (M). Disease course code: relapsing remitting (RR) and secondary progressive (SP).
