Correlations between rate of utterance and nasal airflow

corr_rainbow air rate

Figure 1: Correlation between nasal airflow and rate of utterance of the Rainbow Passage uttered at a normal rate.
Pearson correlation = 0.499 (p=0.049).

corr naomi air rate

Figure 2: Correlation between nasal airflow and rate of utterance of the Naomi Passage.
Pearson correlation = 0.688 (p=0.003)

corr naomi rainbow air

Figure 3: Nasal Airflow correlation for the Naomi passage versus the Rainbow Passage.
Pearson correlation = 0.948 (p<0.001)

corr naomi rainbow rate

Figure 4: Rate of utterance correlation for the Naomi passage versus the Rainbow passage.
Pearson correlation = 0.804 (p<0.001)

Please note: The two very strong correlations in figures 3 and 4 are partly a result of the abstracted data for the Naomi passage in table 1 (on the results page). The data abstraction methodology had as its goal the preservation of strong correlations between the paired data for the two passages.
