With the emergence of big news about humanoid robots, it is clear that robotics is rapidly evolving. Perhaps the future of humanoid robots will be silent, unlike the expected "human-like speech"!
Before talking about the silent speech mode of humanoid robots, we might as well review the scene of using electronic devices together: connecting to the network through mobile phones to communicate instantly with distant friends, text, pictures, audio, video and other types of expression are not in the words, a moment is reached.
The Internet is a network connection that transmits data via radio waves. Humanoid robots, as the representatives of the intelligent age, may act as any person or thing around us, so it is logical that it should have the effectiveness of radio communication: to speak in silence! Without having to speak, it can quickly and accurately complete the massive information transfer and feedback.
Humanoid robots: the perfect enforcers of silent communication
Instantaneous transmission of massive amounts of information
In nature, the amount of information carried by the sound emitted by living things is quite limited, and human beings, as a part of nature, are not immune to this "defect". However, humanoid robots are not natural objects, they are the gains of advanced human intelligence, and they have the plasticity of scientific and technological creation, so why not make them into a collection with the ability to instantly transmit massive amounts of information? Silent communication is an achievable direction to reach this goal. Silent communication through radio wave data transmission can complete the rapid transmission of hundreds or thousands of Gs of information, so that a huge amount of information can be transmitted from a humanoid robot to other robots or users in an instant.
"Voices" that break the limits of time and space
It is well known that sound propagation requires a medium and that sound energy is dissipated during transmission. Silent communication uses radio waves that can be deployed and used flexibly in a variety of environments, regardless of geographic location and wiring infrastructure. Therefore, the humanoid robot's silent communication method will not suffer from a lack of information due to distance, so that communication is no longer limited to the immediate, but can also be transmitted thousands of miles away.
Optional extension of "language"
If the humanoid robot's voice is no different from that of a human being, it will only have a single "language" transmission function. On the contrary, if its voice in the silent, is a collection of arbitrary text, pictures, audio, video and other "language" function of the robot, and its communication with the "language" optional will be greatly expanded, but also more able to play the humanoid robot as a class of robotics The humanoid robot can be used as a kind of robot with practical functions as an intelligent device.
Directional "sound" for security and stealth.
Silent communication can also be done in the true sense of directional transmission of "sound", for example, even if the humanoid robot is thousands of miles away, it can also transmit to the designated user's wearable device the required number of songs, and the user can also independently choose to open at any time to enjoy any of the music. This type of communication is not only no longer limited to time and space and "language", but also has a directionality that is more secretive and secure, and is suitable for some occasions that require confidentiality or to avoid attracting attention.
In terms of practical applications, wireless communication technology enables two or more robots to communicate silently and efficiently by effectively exchanging data and working together without physical connection. On the other hand, humans, who are not robots, can also communicate silently with humanoid robots through wearable devices. In the near future, silent communication between humans and robots will be possible everywhere.
Silent Communication: Future Scenarios for Human-Machine "Dialogue"
For example, Li Ming receives information by wearing a headset that supports bone conduction technology. When the humanoid robot transmits news messages for Li Ming, using the sound transmission advantage of piezoelectric bone conduction, he hears the translucent news broadcast audio through the headset, and there is sufficient layering and localisation within the sound field, with a slight sense of air-flow in the breath transmission ability, and sufficient overall audio ambience.
When the humanoid robot transmits songs for Li Ming, the effect is enhanced with high quality thanks to the piezoelectric bone conduction unit featuring many layers and high thickness. Low-frequency sound effects of the volume, texture to maintain the same state with the original sound quality, strong enough to hit the overtones can also achieve just the right state; mid-frequency to maintain a great resolution, good density, very subtle dynamic presentation, showing that the frequency band should be soft and relaxing; sufficient vibration amplitude, so that the piezoelectric bone conduction unit output of the high-frequency brightness of the health of the bright and open but not sharp, clean and balanced.
Product introduction: Piezoelectric bone conduction unit
The piezoelectric bone conduction unit in the headphones is a multi-layer ceramic structure product, each layer thickness is only about 20μm, belonging to the category of piezoelectric conversion element. Each bone conduction unit has gone through rigorous testing of capacitance, loss, impedance and resonance frequency; it is characterised by a large number of layers and a thin thickness, which results in a high-quality enhancement of bone conduction vibration effects and a more distinctive sound effect.
When technology is further advanced, silent communication may no longer be limited to the transmission of information by radio waves, it may be that brain waves send out information, directly translated to the humanoid robot to receive, and the humanoid robot also has the ability to directly reply to the information, then humans will have the rapid transmission of the mind of the "three-body man", and with the advantages of the original mind is not open, the humanoid robot will have the ability to directly reply to the information. Wonderful! In this way, hearing impaired or speech impaired people can also be the same as other people, without any external language can be communication, equal treatment is no longer on paper.
Overall, the silent communication of humanoid robots not only improves the efficiency and quality of human-robot interaction, but also helps create a more harmonious, safe and convenient social environment. With the continuous development of technology, this function will show its potential value and influence in more fields. In the future, we expect to see more intelligent and flexible humanoid robots, which are able to carry on more in-depth and natural interaction with humans through silent communication.
