Final answer:
The Nasal Sentences test is designed to measure nasalance for different speech sounds and is tailored to detect nuances in oral and nasal sound production, making it ideal for assessing specific sound types.
Step-by-step explanation:
The test that allows the assessment of nasalance by type of speech sound is the Nasal Sentences test. This test is specifically designed to distinguish between oral and nasal sounds in speech. It offers different sentences that are constructed to contain high-pressure consonants which are sensitive to nasal airflow. Therefore, it provides a way to measure the nasalance for different types of speech sounds, particularly plosives and fricatives, which are more likely to be affected by velopharyngeal insufficiency or other disorders affecting nasality. The other options, such as the Zoo Passage, SNAP test, Rainbow Passage, and Turtle Passage, are also used to evaluate speech, but they do not specifically focus on assessing nasalance by type of speech sound like the Nasal Sentences test does.
In summary, the Nasal Sentences test can help clinicians and researchers evaluate a person's nasalance across different speech sounds, providing valuable information for the diagnosis and treatment of speech disorders.
The Nasal Sentences test evaluates nasalance across different speech sounds, making it the best choice for assessing the nasal quality of specific types of sounds in speech and it differentiates oral and nasal sounds effectively.
