Responses with a higher Vowels score (i.e. more "natural" pronunciation) correlate strongly with high TOEFL Speaking scores.
- Good: 26-30
- Fair: 18-25
- Limited: 10-17
- Weak: 0-9
What this chart tells us
For the Vowels dimension, there is a strong relationship between vowel sounds in your response and your overall TOEFL Speaking score. To earn a high overall TOEFL Speaking score, you probably need to produce fewer unnatural (i.e. mispronounced) sounds than most other test takers.
- the Vowels score for this response is 45 (i.e. it scored in the 45th percentile)
- 55% of all responses scored higher; 45% of all responses scored lower
- responses with a Vowels score of 45 are consistent with an overall TOEFL Speaking score in the Fair range
- responses with a Vowels score between 59 and 77 scored in the Fair and the High ranges (i.e. where the blue/green bars overlap)
- the Impact of this dimension is 3/4, meaning there is a strong correlation between Vowels and your overall TOEFL Speaking score
