Abstract
The present invention relates to systems and methods for characterizing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising: a mechanical coupler comprising means for restricting the jaw position of the patient; means for recording an utterance; and processing means for determining at least one anatomical parameter of the upper airway from the recorded utterance and comparing the recorded utterance to a threshold value. In addition the present invention relates to the use of the above mentioned systems as a diagnostics tool for assessing obstructive sleep apnea.
Claims3
A system for characterizing at least one anatomical parameter of an upper airway of a patient based on an utterance in the form of a complete unit of speech in spoken language generated by the patient, comprising:
- a mechanical coupler structured to fix a position of a jaw and teeth of the patient and cause a mouth of the patient to have a predetermined diameter while the patient is generating the generated utterance and transmit an audible sound signal comprising the generated utterance;
- a sound recording unit structured to receive the audible sound signal from the mechanical coupler and generate a recording of the audible sound signal;
- and a computing device structured and configured to:
- (i) receive the recording of the audible sound signal, (ii) determine, from the recording of the audible sound signal, a correctness of the generated utterance as compared to and as matching a predetermined utterance in the form of a complete unit of speech in spoken language to be performed by comparing the complete unit of speech of the generated utterance to the complete unit of speech of the predetermined utterance, and (iii) responsive to a determination that the complete unit of speech of the generated utterance matches the complete unit of speech of the predetermined utterance, determine at least one anatomical parameter of the upper airway based on the recording of the audible signal by extracting and analyzing spectral properties of the generated utterance from the recording of the audible signal.
