Electric cochlea Chinese fixed electric stimulation amplitude changing pattern in vitro voice processing equipment

An electronic cochlea Chinese fixed electrostimulation amplitude variation pattern exosomatic speech processing device comprises an audio amplification sampling module, a storage module, a digital signal processor and a signal transmission module, wherein the speech signal processing program of the device comprises a preprocessing unit, an endpoint detecting unit, a speech recognition unit and a feature coding unit; the feature coding unit has a fixed electrostimulation amplitude variation pattern library and a stimulation patter selecting and adjusting module; moreover, the feature coding unit selects a corresponding electrostimulation amplitude variation pattern from a fixed electrostimulation pattern library according to the recognition result of a speech section, and adjusts an electrode channel selection pattern, a stimulation speed variation pattern and stimulation time, thereby finally generating a holonomic electrostimulation parameter corresponding to each stimulation electrode.
