| 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.
