Abstract
A method includes computing one or more values of at least one parameter at respective times during an exhalation of a subject, based on one or more properties of sound passing through air exhaled by the subject during the exhalation, the parameter being related to a concentration of a gas in the air. The method further includes generating an output in response to the values. Other embodiments are also described.
Claims44
A system, comprising:
- an output device;
- and
- one or more processors configured to cooperatively carry out a process that includes:
- receiving a speech signal representing speech uttered by a subject,
- processing the speech signal so as to identify one or more properties of the speech that depend on a concentration of a gas in air exhaled by the subject while uttering the speech,
- based on the properties, computing one or more values of at least one parameter at respective times during the speech, the parameter being related to the concentration of the gas, and
- generating an output, via the output device, in response to the values.
A method, comprising:
- receiving a speech signal representing speech uttered by a subject;
- processing the speech signal so as to identify one or more properties of the speech that depend on a concentration of a gas in air exhaled by the subject while uttering the speech,
- based on the properties, computing one or more values of at least one parameter at respective times during the speech, the parameter being related to the concentration of the gas;
- and
- generating an output in response to the values.
A computer software product comprising a tangible non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by one or more processors, cause the processors to cooperatively carry out a process that includes:
- receiving a speech signal representing speech uttered by a subject,
- processing the speech signal so as to identify one or more properties of the speech that depend on a concentration of a gas in air exhaled by the subject while uttering the speech,
- based on the properties, computing one or more values of at least one parameter at respective times during the speech, the parameter being related to the concentration of the gas, and
- generating an output in response to the values.
