Description

Novel mobile nursing PDA based on voiceprint recognition technology

Technical Field

The utility model belongs to the technical field of medical care equipment, concretely relates to novel removal nursing PDA based on voiceprint recognition technology.

Background

The PDA is a palm computer, and medical PDA has been gradually popularized in various middle and large sized hospitals, and the main functions of the medical PDA include obtaining patient information from HIS, information inquiry, treatment management, and the like.

The mental health hospital is a special place, wherein patients with serious illness generally lack self-control ability. At present, the identification of patients in mental health hospitals is mainly realized by wearing a passive tag wrist strap and a PDA with a tag reader, and the PDA is handed to medical personnel for use. Wherein, passive label wrist strap generally adopts materials such as silica gel to make, shortens life easily at intentional damage processes such as disease violence is torn.

Since vocal cords of any two persons are different in size and shape because vocal organs (tongue, teeth, larynx, lung, nasal cavity, etc.) used by the persons when speaking are very different from person to person. In general, therefore, different individuals can be distinguished by voiceprint recognition techniques. Voiceprint recognition is one of the biometric identification technologies, also called speaker recognition, and includes speaker identification and speaker verification, specifically, a voice signal is converted into an electrical signal, and then the electrical signal is recognized by a computer.

To further illustrate the above objects, structural features and effects of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of the preferred embodiment of the present invention;

FIG. 2 is a top view of the preferred embodiment of the present invention;

FIG. 3 is a bottom view of the preferred embodiment of the present invention;

in the figure: 1. a PDA body; 2. a display screen; 3. a recording key; 4. an infrared temperature measuring probe; 5. a recording port; 6. a voice play port; 7. a charging interface; 8. an audio input interface.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

Referring to fig. 1, 2 and 3, the novel mobile nursing PDA based on voiceprint recognition technology of the present invention includes a rectangular PDA body 1, a display screen 2 and a recording button 3 are disposed on the front side of the PDA body 1, and the recording button 3 is preferably disposed at a position right below the display screen 2, so as to facilitate operation. The side of going up of PDA body 1 is equipped with infrared temperature probe 4 and recording mouth 5, and the downside is equipped with the pronunciation and puts mouth 6 outward and charge interface 7, and infrared temperature probe 4 is used for the body temperature measurement, in case exceed alert temperature, puts mouth 6 outward in pronunciation and carries out the audio alert suggestion. The PDA body 1 is internally provided with a local area network networking module, a voiceprint registration module, a high-speed voiceprint recognition engine and a large-capacity storage medium, the local area network networking module is used for accessing the HIS, the recording port, the voiceprint registration module and the large-capacity storage medium are sequentially and electrically connected, and meanwhile, the recording port, the high-speed voiceprint recognition engine and the large-capacity storage medium are sequentially and electrically connected.

In the preferred embodiment, the PDA body 1 is also provided with an audio input interface 8, preferably on the underside of the PDA body 1. Besides acquiring the voice file of the patient on site through the recording port 5, the pre-recorded voice print file can be input externally through the audio input interface 8. The audio input interface 8 comprises an 8k16bit input interface, an 8k8bit input interface and a 16k16bit input interface. The phone is 8k8bit input, voip and tablet are 8k16bit input, and the mobile phone is 16k16bit input.

The large-capacity storage medium is preferably formed by cascading a plurality of EEPROMs, the EEPROMs have the characteristics of nonvolatility, byte level control, convenience in use and low power consumption, the size of each EEPROM is more than 4Mb, and the model is preferably 25CSM04 of Microchip. The size of each processed voiceprint file recorded through the recording port is controlled within 300k, and the voiceprint file can be sufficiently used with 3-4 25CSM04 pieces.

The voiceprint registration module supports three times of voiceprint registration, a voiceprint model is generated after voiceprint audio is collected, if the voiceprint model is failed to generate, the voiceprint audio is collected again, and if the voiceprint model is successfully generated, the voiceprint registration is successful. After the registration is successful, the voiceprint recognition can be carried out through the high-speed voiceprint recognition engine, and the phrase spoken during the registration is kept consistent with the phrase spoken during the voiceprint recognition verification as much as possible.

The high-speed voiceprint recognition engine supports multi-format and multi-channel lossless conversion and confidence output, simultaneously supports channel feature extraction and channel learning, and supports operating systems such as Linux, RH6.2 and Windows.

In voiceprint verification, firstly, the PDA equipment is used for collecting the voice of a patient, then voice recognition is carried out, the voice is converted into characters, and whether the converted character content is consistent with the previously set content or not is judged. If the identified contents are inconsistent, the patient is required to speak the contents again, and audio re-acquisition and voice content judgment are carried out. If the contents are consistent, voiceprint recognition is carried out, the current voiceprint model is compared with the voiceprint model during registration, whether the voiceprint model is the voice of the same person or not is judged, if voiceprint verification fails, the audio needs to be collected again, if voiceprint verification succeeds, the identity verification is finished, and the identity of the current patient is confirmed.
