Abstract
Abstract A method of measuring the degree of nasality in human voice sounds by independently isolating and measuring without leakage the exhaled air flow rate through the nose and the exhaled air flow rate through the mouth of a person resulting from the utterance of a sound and determining the ratio of the two air flow rates.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
Apparatus for measuring the degree of nasality in human voice sounds comprising means for independently isolating and measuring without leakage the exhaled air flow rate through the nose and the exhaled air flow rate through the mouth of a person resulting from a phonation, and means for determining the degree of nasality by comparing the air flow rates.
Claim 2
Dependent Claim
58 words
Apparatus for measuring the degree of nasality in human voice sounds comprising means for independently isolating and measuring without leakage the exhaled air flow rate through the nose and the exhaled air flow rate through the mouth of a person resulting from a phonation, and means for determining the degree of nasality by comparing the air flow rates.
Claim 3
Dependent Claim
69 words
Apparatus for measuring the degree of nasality according to claim 1 including a unitary cover adapted to be sealed to the face of a person for receiving exhaled air flow without leakage from both the nose and mouth and having a divider for isolating the exhaled air flow of the nose from the mouth and transmitting the air flow to independent sensors for producing outputs representing air flow rates.
Claim 4
Dependent Claim
53 words
Apparatus for measuring the degree of nasality according to claim 1 including a cover for each of the nose and mouth adapted to be sealed to the face of a person for receiving exhaled air flow without leakage, each cover including a sensor for producing an independent output representing exhaled air flow rate.
Claim 5
Independent Claim
54 words
A method of measuring the degree of nasality comprising the steps of independently isolating and measuring without leakage the exhaled air flow rate through the nose and the exhaled air flow rate through the mouth of a person resulting from a phonation and determining the degree of nasality by comparing the air flow rates.
Claim 6
Independent Claim
54 words
A method of measuring the degree of nasality comprising the steps of independently isolating and measuring without leakage the exhaled air flow rate through the nose and the exhaled air flow rate through the mouth of a person resulting from a phonation and determining the degree of nasality by comparing the air flow rates.
Claim 7
Dependent Claim
45 words
A method of measuring the degree of nasality according to claim 4 wherein in comparing the air flow rates a value is obtained by dividing the exhaled air flow rate through the mouth by an output representing the exhaled air flow rate through the nose.
Claim 8
Dependent Claim
45 words
A method of measuring the degree of nasality according to claim 4 wherein in comparing the air flow rates a value is obtained by dividing an output representing the exhaled air flow rate through the nose by the exhaled air flow rate through the mouth.
Claim 9
Dependent Claim
64 words
A method of measuring the degree of nasality according to claim 4 wherein in comparing the air flow rates a value is obtained by dividing an output representing the exhaled air flow rate through the mouth by an output representing a value which is the sum of the exhaled air flow rate through the mouth and the exhaled air flow rate through the nose.
Claim 10
Dependent Claim
64 words
A method of measuring the degree of nasality according to claim 4 wherein in comparing the air flow rates a value is obtained by dividing an output representing the exhaled air flow rate through the nose by an output representing a value which is the sum of the exhaled air flow rate through the mouth and the exhaled air flow rate through the nose.
