Voice operation jumps into the smart home human-machine interface star. Amazon's voice assistant Alexa is at the CES exhibition in 2017. Smart home appliances such as TVs, refrigerators, air conditioners and washing machines, and even accompanying robots have been introduced into voice operation functions. The killer app for smart homes.
Ye Hengfen, manager of the research and development department of ITRI's communication system, said that compared with the 2016 CES exhibition, most smart homes still focus on the situation of using mobile phones as the control center and remote control of various smart devices. After Amazon opened the Alexa application programming interface (API) in 2016, it attracted major manufacturers to introduce speech recognition functions. To date, Alexa has 7,000 skills, and 180 suppliers have developed products on this platform, which is likely to become a unified cross-platform calling method.
Ye Hengfen analysis, there are three main driving factors for the growth of voice interface. First, the error rate of speech recognition is reduced. If the speech recognition is below 85%, it does not meet the standard of imported products. The speech recognition rate needs to be more than 95%. At the present stage, the current speech recognition rate has reached 97~98%, which is similar to the accuracy of human identification language. Second, the use of mobile voice assistants has increased, and now many voice requests come from actions. Device, in the case of US users, 20% of mobile phone users have initiated requests for data services by voice type. For example, Google Now’s voice search has grown by 35 times; third, the voice platform API is open, and devices The content and application are imported one after another, so that voice computing will have the opportunity to become the mainstream input type of IoT devices.
In fact, in the smart home field, the function of combining voice and image recognition technology based on artificial intelligence (AI) chips has emerged to improve the device-to-device innovation, such as LG (LG). There are a number of deep learning algorithms based on voice and image recognition for home appliances, and cooperation with Open Network Foundation (ONF), Google and Amazon to improve product interoperability.
However, most of the current speech recognition systems are also subject to background noise, the tone of the speech, the way even the connection of different brands of equipment, etc., will also affect the accuracy of speech recognition. In view of this, Ye Hengfen believes that the direction of the next stage of speech recognition can reduce the background noise interference, naturally recognize the speaker's intonation and the recognition and learning of certain special terms (Lingo).
In addition to the speech recognition function, NVIDIA CO-Pilot has three-in-one multi-recognition capabilities for speech, face recognition and lip recognition, which can be added to the work of Lin Zemin, manager of the component research department of the Electronics and Systems Research Group of the ITRI Center. Accurately distinguishing the instructions expressed by users, this multi-identification human-machine interface technology, to enhance the accuracy and security of recognition, will become the trend of human-machine interface development in the future.

Place the LR44 batteries provided into the compartment in the back of the Remote Control, please insert as sho*/m in the back of the compartment to ensure the polarity is correct.
Programming Instructions
• Plug the Remoce Socket$($)lnto the wall socket(s) and switch on the mams supply, the red LED will flash every second.
• If the LED is not flashing press & hold the manual ON/OFF button for 5 seconds until it Hashes
•Press any ON switch on the Remote Control for approximately 2 seconds and the Remote Socket(s) learn the code. The LED will stop flashing top confirm the codehas been accepted.
• Any number of Remote Sockets can be programmed to one Remote Control ON button to create multiple switching.
• To programme o<her Remote Sockets on different Remote Control ON buttons repeat the prevous steps
• If the mains supply is turned off the Remote Sockets v/ill lose their code and it wil be necessary to re-pcogramme.
Operation:
• Plug your appliance(s) into the Remote Socket(s)
• Press the programmed ON or OFF button on the Remote Control to control the Remote Socket.
♦ The Remote Sockets can also be operated manually using its ON/OFF Button Trouble shooting
If a Remote Socket does not react to the Remote Control please check the followng:
♦ Low battery in tbo Remote Control
• Distance too large between the remote control and the recerver (ensure the range distance is no more than 20 clear Metres) and free from obstacle that may reduce the distance.
• If programming has not been successful, tum the power off and back on then follow the programming steps above.
How to decode
• Press the manual ONX)FF button for 5 seconds until the red LED flashes once per
second to confirm de-coding is successful
♦ Press the ALL OFF switch on the Remote Control for more than 3 seconds, the LED
flashes once per second to confirm (decoding successful.
