Which statement about speechreading measures is most accurate?

• A. Speechreading test results are likely to have a high correlation with measures of visual intelligence.
• B. Intertalker differences are eliminated as a test variable when scoring viseme recognition.
• C. The most realistic measures of speechreading ability are administered in a visual mode only.
• D. The most realistic measures of speechreading ability are administered in a combined auditory-visual mode.

Answer: (A)

Speechreading performance relies heavily on how well someone can visually interpret facial movements and map those visual cues to speech, which in turn depends on the brain’s ability to process and organize visual information. This is why tests of speechreading often show a meaningful relationship with measures of visual intelligence—the same visual-processing skills that support recognizing patterns, tracking moving lips, and maintaining visual information in memory contribute to lipreading success. In other words, the better your visual-spatial and visual-processing abilities, the more efficiently you can extract linguistic information from visual speech cues. Intertalker differences aren’t eliminated simply by scoring viseme recognition, because different talkers display the same phonemes with different facial movements, speeds, and accents, which still affects performance. The most realistic measure of speechreading isn’t universally visual-only; real-world communication often combines auditory and visual information, though exam contexts about speechreading specifically focus on the ability to interpret visual speech cues. The correlation with visual intelligence captures a central, well-supported aspect of why some people are better at speechreading than others.
