An apparatus for informing an operator of an abnormality of a physical information obtained from a living subject, including a physical-information obtaining device which obtains the physical information from the subject via an endoscope and outputs a physical-information signal representing the obtained physical information, a signal converting device which converts the physical-information signal into an analog speech signal having a waveform representing a speech corresponding to the obtained physical information, a speech outputting device which outputs the speech represented by the speech signal, a judging device for judging whether the obtained physical information represented by the physical-information signal is abnormal, and a frequency shifting device which shifts, when the judging means makes a positive judgment, frequencies of the speech output by the speech outputting device, so that the operator is informed of the abnormality of the physical information obtained from the subject.
