At any time you say "Hey Siri" the device hears you, has Apple spied on us?

Personally, I depend heavily on Siri, and I talk to her a lot to quickly implement orders for me, such as: Siri, ask my wife, or Siri. Send a message to my mother, Siri, turn off the TV, and other commands. I even asked Siri to call “my love” and in front of my wife I joke, Siri, who am I? Siri replies, "You are my love," of course, may God have mercy on her. My wife does not accept this kind of banter 😊

But hey, didn't you notice anything? You talk, and Siri hears you and answers, doesn't this mean that the device's microphone is on all the time, so is it possible for Apple to spy on us? What about the device's battery? Doesn't opening the microphone all the time mean the battery is consumed? All these questions need to be answered immediately, now that I doubt Siri and do not expect this betrayal from her after all this time.

How does the "Hey Siri" instant reply system work?

First, you must know, as an educated person who follows Apple, that Apple has blogs in several areas, such as your iPhone Islam, and the answer to this question is found in A blog in the field of machine learningOf course, it is a blog for professionals, but let us simplify the answer to this question, how does the instant reply system work, "Hey Siri" ...

The microphone actually works all the time, but it does not work in the same way that you record your voice or speak on a phone call, otherwise it would have consumed the battery of your device immediately, but the task of the microphone is to convert the sound into waves only and momentarily these waves are not accurate like a normal audio recording so as not to consume Rather, these waves are sent to a processor that works with (Deep Neural Network) technology, and the sound wave segments are matched with the word “Hey Siri” and at this time the probability that this word is identical is given. For example, if you say "Ha Siri," the percentage is 55% matching, and Apple will behave according to this probability.

You should know that Siri is asleep all the time and do not wake up and understand your words unless you press the Siri recall button or the word "Hey Siri" is matched as we explained above, and here it is activated and the microphone works with its full efficiency, but without that, the device's microphone does not record nor understand your speech at all or A conversation from it can be reconfigured and all this is done on your device, and its only purpose is to convert the sound into waves that are divided into sections and give a positive or negative result to match the word "Hey Siri"

Conclusion: Yes, the microphone works all the time in the event that the "Hey Siri" feature is activated, but it works in the mode of converting sound into intermittent waves, and there is no fear that you will be spied on because these waves do not represent understandable speech.

What about battery consumption?

The microphone is constantly on, and there is always a matching of sound waves, shouldn't this be consuming a lot of power from the device? Yes, but Apple is doing these operations with great intelligence. The comparison is done quickly and a few waves are compared, but if a match is suspected, more sound waves are compared to make sure of the match, then the matter is done on the energy saving stages, and thus the battery consumption is greatly reduced because the device hears sounds all the time and it is unreasonable That the word “Ya Siri” is compared completely each time. If the word “Ya” is not detected, then there is no need to try to match the sound wave that follows it, which is supposed to be “Siri,” so that the process of matching “Ya” never takes a lot of energy. It is very small and does not compare to the power your device consumes for background processes that happen all the time, such as receiving notifications, updating applications and data, searching for the network, and more.

More than this, this matching process takes place according to your device, its memory capacity and its energy level, and the matching process decreases as the resources become less, so sometimes you may say, Siri, and not hear you unless you repeat it. The reason is that at low power Apple provides this energy to keep your device as long as possible. Therefore, the first "Ya Siri" is nothing but a process of awakening the certainty of the word that follows it.

Also in these processes, Apple uses a very low-power processor, which is a processor that works all the time and is called "AOP" or "Always On Processor". This processor is part of the processor that detects movement and calculates it in the health application. This processor works all the time and consumes very little energy compared to the device processor. the main.

ConclusionThere is no fear of energy consumption due to the "Ya Siri" service. The whole process is done according to the amount of energy available in your device and on a processor that works all the time in the main and does not consume much energy.

We know that the article contains information that may be difficult for some, but the answer has been clear, and the explanation is clearly given to those who wish to explain, and for scientists and specialists you can review the source for more detail, even the mathematical equations used in matching.
