2 During the production of nasal consonants like /m/ and /n/, where is the velum positioned?

A Raised against the pharyngeal wall
B Lowered to allow air into the nasal cavity

B Facial nerve
C Vagus nerve
D Hypoglossal nerve

4 What is the primary function of the diaphragm during the respiratory phase of speech production?

A To filter saliva from the airway
