What is the smart speaker?


Called yet connected it's first, a high tech product, then it's a speaker connected directly to the internet through the High Tech product - smart speaker - cheap   This connection allows you to benefit from an integrated voice assistant.

Initially, the original main function was music streaming but it was not interesting. Today several functions have been added to give a plus and leave a simple speaker.

Several manufacturers make sound quality their first goal, while for these qualities come last.

An intelligent speaker (often portable speaker) will allow you to listen to music in two ways:

- By Bluetooth from a smartphone or tablet,
- By streaming from apps.

Several forms and models exist, the wireless or portable speaker, the compact speaker, the multiroom speaker, the small speaker or the large speaker.

How it works ?

Speakers use applications called skills. And by adding these skills to Amazon Alexa parent apps for Amazon Echo, etc., Google Assistant for Google, etc. and Siri for Apple, previously downloaded, you can access the desired functions.

Thanks to these skills, we will be able to add interactive features to the speaker: radio, games, traffic, newspapers, etc..

For the field of home automation, it is necessary to activate the skill on the speaker and the appropriate application on a smartphone.

What to expect ?

The possibilities of use are numerous. The most common are:

- listen to music in multiroom,
- make calls,
- listen to the news,
- ask questions,
- schedule alarms and timers,
- check weather and sports results,
- manage lists of things to do,
- schedule your purchases or make a reservation,
- pilot the house by having the necessary kit,
- lock the doors,
- centralize control of home systems,
- etc.

The driving is usually done by voice.

Invasion of privacy


Here we take extracts from the article of the CNIL France (National Commission for Information Technology and Liberties) of 12/20/2018.

Operating steps

The operating principle of a smart speaker goes through 5 stages:

- Step 1: The user gives an order using a keyword,

- Step 2: The key word pronounced "awakens" the speaker. Some speakers use voice biometry, that is, to have the user record samples of their voice for one reason or another. These data are collected without the consent of the user.

- Step 3: The user provides his request. There are two possibilities:

   . Requests are saved locally,

   . Requests are sent to the cloud, i.e. to servers that keep a request history and the corresponding data (date, time, etc.),

- Step 4: The speaker response sentences are first transcribed into text and then synthesized on the speaker,

- Step 5: The speaker is on standby.


Vigilant point

Three essential points must be respected so as not to harm his privacy. These 3 points of vigilance are:

- First point: The confidentiality of the exchanges

   If the speaker detects one of the pre-recorded keywords, it can activate and record the conversation, even if it is in standby. To remedy this:

A speaker equipped with a microphone activation and deactivation button should be preferred.,

. You have to mute the microphone or switch off the device when you don't want to be listened to,

. You have to warn everyone around you at home,

. Above all, we must supervise children's interactions.

- Second point: The monetization of the ultimate

   The enclosure is at the center of home life. Home living habits are discovered in the presence of the enclosure. The advice provided by the commission is:

. You have to connect services that are really useful for you,

. You have to be vigilant about everything that is said in front of the camera.

- Third point: The absence of a screen

   The absence of a screen does not allow to have a preview on all the recorded data. The advice recommended in this case is:

. Always go to the "dashboard" to delete the history of conversations.
