1. A method for communicating information about a patient's sleep, comprising the steps of: capturing analog sound information spontaneously emitted by a patient during a period of time associated with a sleep period of the patient; converting the analog sound information into a digital form; storing the digital form of the analog sound information into a first memory; dividing a portion of the period of time associated with the sleep period into a plurality of epochs, each of the plurality of epochs having an attribute, the attribute being the same for each of the plurality of epochs; determining, using a computer with corresponding computer code, a value of the attribute for each of the plurality of epochs; selecting an epoch from the plurality of epochs in which the value of the attribute satisfies a specified criterion; retrieving from the first memory the digital form of the analog sound information associated with the selected epoch; converting the retrieved sound information into an analog form; outputting the analog form of the retrieved sound information to a listener.
