摘要： A speech airflow measurement system comprises a feature extraction module configured to receive input signals associated to a user from at least a first sensor and a second sensor, and determine an estimated shape and/or rate of airflow from at least part of the input signals. The system may further comprise a headset comprising the first sensor positioned within at least the first airflow of the user; the second sensor positioned within at least the second airflow of the user; and a shielding member adapted to shield the first sensor from the second airflow, the shielding member adapted to provide an air gap between the shielding member and a face of the user while the headset is in use by the user.
