Final answer:
To calculate the speech intelligibility as a percentage, divide the number of intelligible words by the total number of words and multiply by 100.
Step-by-step explanation:
To calculate the speech intelligibility as a percentage, you need to divide the number of intelligible words by the total number of words, and then multiply by 100. In this case, the student spoke a total of 100 words and 25 were intelligible. So, the speech intelligibility percentage would be:
- 25/intelligible words / 100/total words x 100 = 25%
