Abstract
A method for equalizing a speech signal generated within a pressurized air delivery system, the method including the steps of: generating an inhalation noise model (1152) based on inhalation noise; receiving an input signal (802) that includes a speech signal; and equalizing the speech signal (1156) based on the noise model.
Claims15
A method for equalizing a speech signal generated within a pressurized air delivery system, the method comprising the steps of:
- generating an inhalation noise model based on inhalation noise;
- receiving an input signal that includes a speech signal;
- and
- equalizing the speech signal based on the noise model, wherein the pressurized air delivery system includes a mask into which the speech signal enters and that has a transfer function that affects the speech signal and wherein the noise model characterizes the transfer function such that equalizing the speech signal removes at least a portion of the effects of the transfer function.

A device for equalizing a speech signal in a pressurized air delivery system, comprising:
- a processing element;
- and
- a memory element coupled to the processing element for storing a computer program for instructing the processing device to perform the steps of:
- generating an inhalation noise model based on inhalation noise;
- receiving an input signal that includes a speech signal;
- and
- equalizing the speech signal based on the noise model, wherein the pressurized air delivery system includes a mask into which the speech signal enters and that has a transfer function that affects the speech signal and wherein the noise model characterizes the transfer function such that equalizing the speech signal removes at least a portion of the effects of the transfer function.
