The Best Voice Assistants For Cars

Technology has become an indispensable factor in all sectors and no exception to the automobile. In fact, it would seem impossible to imagine new car models without the typical sensor that warns you not to have fastened your seat belt, without infotainment systems, screens, and Dashcam cameras for cars.

The Best Voice Assistants For Cars

In recent years, technology has made great strides and today it is possible to bring our favorite home voice assistant even in the car. For the most advanced cars it is possible to use the voice assistant via Android Auto or Apple Carplay, while for Alexa, this native integration is only possible via Echo Auto. A device similar to Alexa for your home but designed for the needs of those who drive.

What to ask a voice assistant in a car

I am sure that many of you have already tried the usefulness of having a voice assistant at home, it is very useful for obtaining quick information and for executing voice commands without using your fingers. Let’s see with some examples what to ask a voice assistant in the car and why it is useful.

These are just some of the many examples we can interact with a voice assistant while driving. Obviously, for each voice command, it is necessary to precede “Ok Google”, “Hey Google”, “Hey Siri” or “Alexa” depending on the installed voice assistant.

Add the Google Assistant to your car

Taking Google with us in the car is quite simple if we have a car equipped with Android Auto. This is a standard created by Google that allows you to extend some features of an Android smartphone directly on the main dashboard of the car. In order to use Google Assistant in the car, your car must therefore be equipped with the Android Auto standard and your smartphone has an Android 10 or later operating system.

Configuration procedure

If you have a car with Android Auto onboard and a smartphone with at least Android 10, you can proceed with the configuration. The first step is to download the Android Auto app from the store, then you need to configure the smartphone with Android Auto via USB cable.

Voice Assistants

On the official website, you will find all the steps to be able to do it quickly. To check if your car is compatible, look here. Once configured, you can activate Google Assistant from the dedicated button on the car’s steering wheel.

Use the Google Assistant via bluetooth headphones in the car

If you don’t have Android Auto, another alternative to communicate with the Google assistant is through the use of bluetooth headphones. They are very useful in the car even when your car does not have a hands-free system or when the listening quality of the car’s bluetooth offers a very bad experience. Obviously, the possibilities of use via bluetooth headphones are limited to the sole interaction with the voice assistant, thus excluding integration with the car audio system, but it is a good starting solution.

To do this, simply pair the bluetooth headphones to your Android smartphone, from the bluetooth settings by pressing on “Pair device“. Here you will find more information about it. You can then call up Google Assistant after wearing the Bluetooth headphones directly via a button or touch area.

Electromagnetic Wave

Today more than ever, both for work and for pleasure, our life is conditioned by technology increasingly advanced and constantly updated. So as to condition, in each of us at Techy2Tech, frequent renewal of the devices we use in our daily activities, from ‘inevitable smartphone to tablet, from laptop to PC as well as, of course, the most common household appliances, which no one could do without.

Electromagnetic Wave

The physical force capable of moving all this set of devices, making them functional, ensuring connections and connections, is called the electromagnetic field, and the set of waves that propagate the energy constitutes its spectrum.

Electromagnetic waves of natural origin

To feed itself, the electromagnetic field needs sources, artificial, of course, but also natural. Often, in fact, it is believed that these emissions are only a phenomenon linked to the various technologies created by man, such as X-rays, for example, used in diagnostics, or television and radio antennas, or even base stations for mobile telephones. All correct of course, but, it is good to know, there are also natural electromagnetic fields, of strong intensity, even if of short duration, generated by the static atmospheric field, supported by terrestrial magnetism and solar radiation. Let’s just think, for example, of the electrical charge produced by lightning during a strong storm and the damage it can cause if we do not protect our home from lightning and appliances from the resulting voltage fluctuations.

In this article, after having illustrated the main details, we will analyze the specific characteristics of electromagnetic fields, including the types of waves present in the environment, we will present a hint of the characteristics of Wi-Fi and Bluetooth technologies, and of the transmission standards of mobile telephony. , to which powerful transmitters correspond and to which, especially with regard to the upcoming 5G, are often associated with perplexities related to the possible danger of electromagnetic fields.

What is an electromagnetic field?

The basis is, perhaps, only apparently trivial: an electromagnetic field is the combination of an electric and a magnetic source. From a practical point of view, it can be said that electric and magnetic fields are found wherever electric currents flow, that is, for example, in household circuits, in any electrical appliance, or in high-voltage lines.

Let’s break down the details:

The electric field: whose unit of measurement is the volt per meter (V / m), is created by the difference in voltage, or potential, due to the presence of one or more electric charges, which cause the electrons to thrust to power the energy. . It is easily shielded and potentially braked, in its power, by normal materials and objects of common use, such as wood, metal, furniture or walls. The electric field, whose strength increases in direct proportion to the increase in voltage, is produced even if the device to which it is connected is momentarily switched off.

Anatomy of an Electromagnetic Wave

The magnetic field: measured in microtesla (μT), is generated by the transit and circulation of electric current through cables and devices, the origin of the flow of electrons, increasing in intensity the higher the current itself. Contrary to the electric field, the magnetic field is not stopped by common materials and furnishings, so much so that it can easily pass through partition walls and walls of buildings, and is produced only by switching on a device, that is when the passage of electric current.

And it is precisely the union of these two elements that give rise to the definition of electromagnetic fields, widespread and present everywhere in the environment, generated by natural sources, such as the energy accumulated in the atmosphere after a storm, for example, but also by many artificial, numerous and articulated, coming from the most common household appliances or technological and health devices.

Best Anonymous Chat Apps

Today, free messaging applications are the order of the day. Some are more popular than others, but always depending on the country. For example, in China, there is no one without Wechat, and in South Korea, absolutely everyone chats for free with KakaoTalk.

Carbon Footprint

Although in recent years awareness has increased about why a green and environmentally friendly lifestyle is important, people still have many doubts about it and the necessary measures are not always taken.

Carbon Footprint

The good news is that more and more companies are joining the environmental cause through incentives, products and services that help offset their carbon footprint, making it more viable to reduce the impact of climate change. Today we will see how to reduce your carbon footprint and make an unforgettable Christmas gift at the same time.

What is the Carbon Footprint?

The carbon footprint is an indicator that refers to the amount of CO2 emitted by an individual, organization, event or product and serves to measure the impact that these have on the environment.

Through our consumption and lifestyle, we emit greenhouse gases (GHG). For example, when we buy pants, a computer or travel an aeroplane, we are contributing, to a greater or lesser extent, to CO2 emissions.

All our actions have an impact on the environment and, therefore, it is important that we are aware of the products we choose to buy or the means of transport we use. There are even calculators that measure in kilos of carbon dioxide the amounts of CO2 emissions that occur due to a specific action or lifestyle of a person.

To do our bit to curb pollution and avoid the effect of climate change, it is important to offset our carbon footprint. Above all, considering that around 50% of the CO2 emitted into the atmosphere takes 30 years to disappear; 30% last several centuries and 20% last thousands of years.

How to offset the Carbon Footprint?

The reality is that carbon dioxide, in addition to being a pollutant for the environment, is also an important nutrient for plants and trees. The problem is that the CO2 emissions generated by humans exceed the absorption capacity of the vegetation. So how do you reduce your carbon footprint? With environmental initiatives that allow the reforestation of forests, the planting of trees and, in general, that increase the vegetation on the planet.

At, we show you the Eco Rating score that is assigned to mobile phones taking into account the processes of obtaining the raw material, transport to the production plant, manufacture of the device, its packaging, transport and use. A higher score will indicate a lower carbon footprint.

Although this will not eliminate environmental pollution overnight, in the long run, as more people and organizations support these movements, we will achieve a cleaner and purer atmosphere. Now, another way to contribute to the environment through sustainable technology. But what is this about?

The sustainable technology is related to replacing polluting energy sources by renewable. For example, nowadays the use of paper is avoided and more digital sources are used. Just as a virtual meeting is implemented through digital means, instead of using a fuel-powered vehicle for a small meeting.

By buying and giving away from, people have the opportunity to offset the carbon footprint generated by the manufacture of the devices they acquire. Our initiative is to offer three environmental compensation projects to people, among which they can choose one with which they most identify.

The projects include forest conservation, reforestation or agriculture programs, so that every time you shop at, you will be helping the planet while giving something special and unique to your loved ones. This is the time to give away or buy technology knowing that you are doing what you can to reduce environmental pollution.

Innovation in Television Technology

Those of us who dedicate ourselves to innovation in television services and their relationship with the online world use the term “traditional TV” to refer to the “other” TV, the one of all life, but this qualifier is somewhat arrogant and ignores the incredible vitality of TV as we have known it for 75 years: every night, 4 billion people gather in 1.5 billion homes across the globe to watch television. Traditional TV is perhaps the most eminent icon of world popular culture of the 20th century, and if it seems certain that its future will be linked to that of the next icon of the 21st century, the Internet, the truth is that this evolution has only just begun.

Innovation in Television Technology

Ultimately, the appeal of television lies primarily in its content. What are the content exploitation models that have brought about the undeniable success of traditional TV? The television grid is thus nourished by two different sources:

That of the TV networks themselves, both public and private, that produce their own content or add that of third parties and distribute it openly or through paid services.

The world of cinema, controlled very strictly by the big Hollywood studios, which exploit the films according to a sequential model of distribution windows like the one shown in the figure.
Timeline of cinema distribution windows

According to this scheme, you can enjoy a movie at home shortly after its theatrical release by buying or renting the DVD, or wait a few more months for the movie to be distributed on a pay-TV service or, later, on free chains. Other delayed content, such as series, have also evolved into sequential exploitation models with different window configurations, initially distributed on television and later on the rental and purchase market.

Traditional TV then relies on a very closed scheme of a general selection of content and temporal control of its distribution. On the Internet, on the other hand, the personal decision as to what and when to enjoy the content prevails. It is normal then that when these two opposing worlds collide in the audiovisual field, sparks begin to fly:

Internet cinema consumption services are becoming more and more popular, with Netflix in the US as a paradigmatic example. These services allow the enjoyment of recent releases for a price more or less equivalent to the rental of a DVD and also give access to older catalogue collections for a fixed monthly fee.

If online video services undermine the enormous profitability of the DVD rental and sale market, Internet piracy represents the dreaded arrival point on the path to destroying the value of audiovisual content. Interestingly, even in the case of piracy, there are agents who obtain commercial benefits, such as mass storage providers in the network or link pages that profit from advertising added to their portals.

Some analysts predict the intensification of the so-called cord-cutting or loss of pay-TV users, due to the appearance of alternatives in the consumption of delayed content, notably the cinema. In this scenario, the value of pay-TV would be reduced to that of its live events, which are still very effectively controlled outside the online world.

Advertising, an alternative source of profit for TV networks (and the only one for which they are distributed freely) may lose value in the market due to the evidence that more and more people are distracted from TV or follow it in a way little concentrated while using her mobile devices and tablets on the couch at home The entire industry recognizes that this attention needs to be recaptured by proposing second-screen experiences, but no one yet knows how to do it effectively.

New to this continent without maps of the television of the future, perhaps the industry has been too busy analyzing business risks instead of observing user behaviour and asking what it is they want. At Telefonica Digital we have used the CDI ( Customer-Driven Innovation ) innovation methodology to analyze the problems and needs, latent or explicit, of users in the field of new TV services. What have we learned in the process? Some example user insights are:

Content discovery: People are overwhelmed not only by the vastness of content available but also by the sheer number of recommendations they receive, explicitly or implicitly. Even the most valued recommendations, such as those from trusted friends, end up being forgotten when deciding what to see. The preferred form of discovery should integrate recommendations from trusted sources when searching for content for immediate viewing.
TV and the social environment: Live television connects people with a shared reality and offers opportunities for socialization.
Video ecosystem: using a PC, tablet or smartphone is the easiest way to search for content and plan what to watch, but television is still the preferred screen to enjoy it.º

Firefox OS

More specifically the question would be why it is now technologically possible.

Firefox OS is an operating system for smart mobile phones, also called smartphones. Its main distinguishing feature is that it allows you to create applications using the same technology as that used to make web pages. It has been possible due to the technological development in recent years of both terminals and web browsers until reaching a development such that they are already capable of providing outstanding user experiences. Let’s see how we got here.

Firefox OS

The first mobile web browsers to become popular, like Opera, had very limited features. The hardware of that time was so limited that many browsers had to resort to solutions such as intermediate servers doing part of the task. They did their job decently in most cases but they were far from what one would expect.

A substantial change occurred with the arrival of the iPhone. With a terminal with much-improved capacity and a much larger screen than usual at that time, a user experience was significantly better than the existing one.

For complex applications, Apple introduced a web application development kit at the time. The idea was that applications could be developed that were downloaded from the network and ran in the web browser with the same appearance of the native applications of the phone. What happened is that this type of application never fully succeeded. The reasons were various. One important, that technological limitations made the experience not what users wanted.

The next step comes when Apple introduces its native app development kit. By then, the terminal’s processing capacity had improved over the first models. In addition, implicitly or explicitly, Apple took the technological option of substituting an “interpreted” language for a “compiled” one for the creation of applications.

“Compiled” means that the translation from the language that programmers speak to the language that machines speak is done when an application is created. “Interpreted” means that the translation is performed at the moment the mobile executes the application. This is why “interpreted” applications are slower.

Thanks to the change, new Apple applications could run faster. In other words, Apple had made decisions that solved the weak point that was the processing capacity of the terminals of that time.

A little later, Google presented its environment for creating applications on the Android operating system. In it, applications are created using the Java programming language. This language is halfway between the “interpreted” and the “compiled” languages, so it has intermediate performance between the two. Technically what you do is compile a code (this makes it fast) and then run it in a virtual machine (this makes it slow). In other words, the improvement in the capacity of the terminals made solutions other than the totally optimal ones beginning to be possible.

The Firefox OS environment that Mozilla and Telefónica Digital have created mainly is based on the use of HTML5 technology , which is what is used to create web pages. The Javascript programming language is used to program the applications. It is an interpreted language, that is, the slowest of all the types mentioned in this post. This means that it is a technology that needs a mobile phone with higher features. That is why it is the one that could be developed later.

At the present time the capacity of the terminals is more than sufficient. Partly thanks to the great effort of internal optimization of web browsers in recent years to make Javascript work faster. This has been noticed by users in the higher speed of our online applications such as email or news readers.

What remained to be done, and this is what Mozilla and Telefónica Digital have done , is to create an environment that allows a web application to access the basic capabilities of the phone. How to make calls, send messages, create connections to send data or access the calendar.

One of the main objectives in relation to the Internet is for it to “fly” within the home even if we have all connected at the same time. Important steps have already been taken with fiber where speeds of 100 Megabits per second are being offered. It is precisely in this evolution that a novelty appears: a plastic fiber.

 Fiber Optic Cable

Let’s put ourselves in the situation. Glass fiber optics are too expensive for home use and unwieldy. That is why it is usually installed from the central to the door. Inside the home, there is either copper cable or WiFi, which give good transmission quality, but needs to continue improving. The plastic fiber optic, which can be installed inside the home, allows maintaining and even increase the speed and display “extremely high definition” content. Plastic fiber is also much more manageable than glass fiber, as it can be easily bent and is not as brittle as glass.

Another advantage of the plastic optical fiber is that with this system you do not need to have an independent channel inside the home to deploy it, since it is made of non-conductive materials of electricity, of clear plastic. In fact, you can share the routing of the electricity cables and avoid the dreaded chases.

In the end, what interests us users is the economy and the simplicity of installation. Unlike fibreglass that need connectors for more than 30 euros and professional installers, plastic fiber does not need them. It is only cut and plugged in, which makes its use and installation cheaper if you are a little handyman you could almost put it on without help.

The question is obliged: and why is it not used already? Because in recent years it has been improved until it meets all the aforementioned advantages to enter the home in optimal conditions. Telefónica is currently working on a plastic fiber research project aimed at making the most of the advantages of this technology.

Fiber optic networks in the home are already a reality, an economic and future solution. This future happens to be a combination of wired and wireless technologies, coexisting to offer the end-user full connectivity.

X-ray to copper and fiber options

Today, category 5 copper is widely used for residential environments, since it can be installed without the need for specialized equipment or personnel. But this type of cable is designed for 100Mbps, so to reach 1Gbps it is recommended to use category 6 copper cable, which is no longer so easy to install and is more expensive. In addition, you need a separate pipeline within the home for deployment.

However, fiber optic networks can be deployed over existing conduits, as they are not created or affected by electromagnetic interference and are not made of electrically conductive materials. Within the fiber optic options, if price and ease of installation are taken into account, the most suitable for a residential environment is plastic fiber optic.
