Equipment of recording of blue tooth of portable low power comsumption speech accurate changeover is a character

C1 of pen of recording of search dog intelligence uses the NRF52810 SoC of Nordic, wireless transmission recording undertakes turning writing to smartphone APP

Norwegian Oslo–The blue tooth of NRF52810 low power comsumption that the company of dog of high-tech company search that –Nordic Semiconductor announced to headquarters is located in Beijing on August 6, 2019 chooses to use Nordic (Bluetooth®Chip of level of system of Low Energy (Bluetooth LE)) , for its C1” of pen of recording of intelligence of “ search dog provides wireless link.

Equipment of recording of blue tooth of portable low power comsumption speech accurate changeover is a character

C1 of pen of recording of search dog intelligence the solution is compositive equipment of transcribe of speech of blue tooth of portable low power comsumption and exclusive smartphone APP, support word of lard one’s speech with literary allusions of high-definition recording, recording and simultaneous interpretation to wait, use at interviewing, make peace of notes notes, meeting grooms wait for setting. This recording pen deployed microphone of Gao Lingmin of total number word, apply search dog to grind oneself SmartVoice number falls a confusion of voices is algorithmic, implementation voice high fidelity is reductive. C1 of pen of recording of intelligence of dog of indication search of result of test of lab of search dog speech can realize the word of speech lard one’s speech with literary allusions that is as high as 95% to identify accuracy rate.

The blue tooth 4.0(in C1 of pen of recording of search dog intelligence and user reachs Nordic NRF52810 SoC taller version) blue tooth of low power comsumption is offerred between smartphone or the facility that provide blue tooth of low power comsumption wireless join, can transmit the speech data of transcribe the smartphone with low defer, and pass ”APP of pen of recording of “ search dog change continuously for the character. In the meantime, the user can have recording file interpret of Chinese and English each other inside APP. Pass APP, the user can send recording and text document high in the clouds, undertake retrieve and administrative and need not transcribe.

Of pen of recording of search dog intelligence can charge batteries can fall in successive transcribe mode offer be as long as 16 hours to use time, and be as long as 20 days to bide one’s time time, this part is attributed to Nordic SoC exceed character of low power comsumption. NRF52810 has the character of electric current of RX/TX of 4.6mA peak value of 2.4GHz radio, can utmost ground reduces power comsumption, its are full automatic system of power source management can reduce power comsumption to even lower than NRF51 series SoC 80% .

In addition, search dog chooses to use NRF52810 SoC for C1 of pen of its intelligence recording, because its offerred blue tooth 5 support, include bandwidth of double wireless and primitive data (2Mbps) , eightfold advertisement is patulous (advertisement data package effective load size raises to 251 byte) broadcast ability, and improvement channel coexistence is algorithmic.

Radio of much agreement of the 32 Arm®Cortex®M4 processor that the parts of an apparatus of SoC of NRF52810 much agreement of Nordic tied a 64MHz and 2.4GHz (support blue tooth 5, ANT™ and have) of software of 2.4GHz RF agreement only, have 24kB RAM of Shan Cunhe of lower radio power comsumption, 192kB. NRF52810 SoC cooperates inn of agreement of newest version S112, this is to accord with blue tooth the RF agreement software of 5 standards.
