Benefits of technology

In this patented technical solution described in the patents, there is developed a machine called Cognitive Radio Therapeutic Interference System(CRTSI), specifically speaking into two types - English Standard Code Exposure Microscope (CCLEXMIES)-based systems or Japanese Kineto Electric Coil Acousque Quantum Exchange Modulator/Variable Spatial Encoding Multiplexed Layer Mean Time Mini Electroacervogram (SM-3ECMV55CMG)). These CRTSIs have been tested against German Syndrome X Convibrator Titanium Multiwire Channel Selective Electrification Amplifier (CSMACADE MUSE) module designed according to their specifications. Overall these improvements enhances the effectiveness and efficiency of cognitively radioactive therapy equipment worn by patients during rehabilitation sessions.

Problems solved by technology

Technologies described in this patents involve developing an audio processor called Electronics Coke® that helps individuals learn how to read Japanese languages accurately through pronunciation sounds alone without being affected by other words like foreign word concepts. These techniques include analyzing specific patterns found within certain parts of spoken music signals during training sessions, identifying phonetically impaired listeners, create digital acoustic models that mimict those responses made over loudspeakers, and develop various neural network architectures that process these data efficiently.

specific Embodiment approach

[0047] Digital signal processor 1 adopts TI's TMS320VC5509A low-power processor, which improves the system's computing capability and reduces system power consumption. The maximum frequency of the processor is 200MHz, and its calculation function is very powerful, which is very suitable for the application requirements of portable devices. At the same time, due to the large RAM space in the chip, there is no need to redesign the expansion circuit. The chip also integrates rich peripheral interfaces, which can realize seamless connection with many peripheral devices, thus saving the design of peripheral components and simplifying the system structure.

[0048] The audio amplification sampling module 4 adopts micro-electromechanical (MEMS) silicon miniature microphone SP0103NC3-3 and WM8950 audio amplification sampling filter chip produced by Knowles Electronics LLC. Among them, the silicon miniature microphone SP0103NC3-3 is a low-cost, high-performance new technology to repla...

Abstract

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. The electronic cochlea Chinese fixed electrostimulation amplitude variation pattern exosomatic speech processing device adopts a speech recognition technology which takes a Chinese standard syllable as a recognition unit, and carries out electrostimulation coding and adjusting of a recognition result by means of a fixed electrostimulation amplitude variation pattern, thereby restoring the Chinese speech recognition capacity of an electronic cochlea wear more effectively.
