1. An implantable system configured to be implanted in a patient, comprising:
- an accelerometer;
a neural stimulator configured to deliver neural stimulation to a neural target; and
a controller configured to use the accelerometer to detect laryngeal vibration and to also use the accelerometer to detect at least one of heart sounds or respiration, and configured to deliver a programmed neural stimulation therapy using the neural stimulator and using at least detected laryngeal vibration as an input to the programmed neural stimulation therapy.

Abstract
An embodiment of an implantable system configured to be implanted in a patient includes an accelerometer, a neural stimulator, and a controller. The neural stimulator is configured to deliver neural stimulation to a neural target. The controller is configured to use the accelerometer to detect laryngeal vibration or coughing, and is configured to deliver a programmed neural stimulation therapy using the neural stimulator and using detected laryngeal vibration or detected coughing as an input to the programmed neural stimulation therapy.
