Table 2. Effect of fPL/ACP on phonation and articulation on day 154.
| Without fPL/ACP | With fPL/ACP | |
| Speech intelligibility | ||
| 100 Japanese phonemes (%) | 68.6 ± 10.8 | 73.3 ± 2.3 |
| Bilabial consonants (%) | 68.0 ± 9.8 | 83.0 ± 7.7 |
| Denti-alveolar consonants (%) | 73.3 ± 12.9 | 77.0 ± 3.3 |
| Velar consonants (%) | 25.0 ± 16.8 | 25.0 ± 16.2 |
| 100 words (%) | 95.5 ± 3.6 | 98.5 ± 0.9 |
| Maximum phonation time (s) | 10.7 | 12.8 |
Data for intelligibility are given as mean ± standard deviation (n = 4).
