A prosthetic hearing device comprising:
- i. a sensor for detecting a speech;
- ii. a speech recognition processor that performs speech recognition on the detected speech, wherein the speech recognition processor performs speech recognition, in view of at least one of a physical state of the user and an operating condition of the prosthetic hearing device;
- iii. a speech generator that analyzes results of speech recognition to comprehend a semantic meaning in the detected speech and transforms the detected speech into a speech having a speech form assistive in understanding the semantic meaning in the detected speech;
- iv. an output device that outputs the generated speech to a user;
- and
- v. an input device, wherein the speech generator, when receiving a reproduction instruction through the input device from the user, reproduces the speech previously produced.
