1. A system comprising:
- an external device; and
an implantable medical device (IMD) comprising;
a pulse generator configured to provide at least one of pacing therapy pulses, cardioversion shock pulses, or defibrillation shock pulses to a heart;
an acoustic transducer configured to receive acoustic energy from within a patient'"'"'s body and generating electrical audio signals in accordance therewith;
sampling circuitry and an analog-to-digital converter configured to produce digitized samples of a signal received from the acoustic transducer;
speech recognition circuitry configured to extract a voice command from the digitized samples;
circuitry configured to begin storing, in response to the voice command, a plurality of samples of the digitized acoustic signals including voice sounds in a storage medium; and
a communication circuit operable to communicate with the external device, the communication circuit for communicating the recorded samples to the external device.

Abstract
An implantable medical device such as a cardiac pacemaker or implantable cardioverter/defibrillator with the capability of receiving communications in the form of speech spoken by the patient. An acoustic transducer is incorporated within the device which along with associated filtering circuitry enables the voice communication to be used to affect the operation of the device or recorded for later playback.
