C'est quoi l'enceinte connectée ou intelligente ?


Meilleure, enceinte intelligente et pas chère  Appelée aussi bien enceinte connectée qu'enceinte intelligente, locution chère à beaucoup. C'est d'abord, un produit High Tech , ensuite c'est un haut-parleur connecté directement à internet par l’intermédiaire du Wi-Fi. Cette connexion permet de bénéficier d’un assistant vocal intégré.

Au départ, la fonction principale initiale était la diffusion de musique comme pour une enceinte Bluetooth mais ce n'était pas intéressant. Aujourd’hui plusieurs fonctions se sont ajoutées pour donner la meilleure utilisation et sortir d'une simple enceinte.

Plusieurs fabricants font de la qualité sonore leur premier objectif alors que pour ces qualités viennent en dernier.

Une Enceinte connectée (souvent enceinte portable), à l'instar de l'enceinte Bluetooth va permettre d’écouter de la musique de deux façons :

- Par Bluetooth depuis un smartphone ou une tablette,
- Par streaming depuis des applications.

Plusieurs formes et modèles existent, l'enceinte sans fil ou portable, l'enceinte compacte, l'enceinte multiroom, la petite enceinte ou la grande.


Comment ça marche ?

Les enceintes sans fil utilisent des applications appelées skills. Et en ajoutant ces skills aux applications mères Amazon Alexa pour Amazon, etc., Assistant Google pour Google, etc. et Siri pour Apple, préalablement téléchargées, on peut accéder aux fonctions désirées.

Grace à ces skills, on va pouvoir ajouter des fonctionnalités interactives à l’enceinte : radio, jeux, trafic, journaux, etc.

Pour le domaine de la domotique, il est nécessaire d’activer la skill sur l’enceinte ainsi que l’application appropriée sur un smartphone.


A quoi s'attendre ?

Il y a de nombreuses utilisations. Celles qui sont les plus fréquentes sont les suivantes :

- écouter de la musique en multiroom,
- passer des appels,
- écouter les nouvelles,
- poser des questions,
- programmer des alarmes et des minuteurs,
- vérifier la météo et les résultats sportifs,
- gérer les listes de choses à faire,
- programmer ses achats ou faire une réservation,
- piloter la maison en s'équipant du nécessaire connecté,
- verrouiller les portes,
- centraliser le contrôle des systèmes à la maison,
- etc.

Le pilotage se fait généralement à la voix.

The Max

It is a premium speaker, smart and connected . Personalization is central to Google's concerns in this device. This is how, in a household of several people, she can distinguish voices and is not mistaken when someone asks her to do something for him.


The inexpensive Mini

It's the little brother of the first Google Home. It takes the form of a small pebble running under Google Assistant, Google's artificial intelligence.

Other types


Here are some of the smart speakers that are currently on the market: We can't speak of a better speaker . There are always improvements.

- Sony LF-S50G,
- Onkyo smart speaker P3 and V3,
- Panasonic SC-GA10,
- JBL Link20,
- Libratone Zipp,
- Harman Kardon Allure and Invoke,
- LG ThinQ.

And then there is one speaker that emerges from all the others. It's the Sonos one. It is certainly one of the best models on the market. It has sound power with impeccable audio quality and stereo sound.

This compact Wi-Fi speaker from Sonos is sold in France but does not yet have all the new features: Alexa, Google Assistant, AirPlay 2 for the French language.

- Equipped with multiple microphones.

La commande vocale n'est pas prise en charge dans plusieurs pays. En plus, les skills sont ajoutés au fur et à mesure. D'un autrecôté, il faut savoir qu'il existe des kits de fixation murale et des supports adaptés mais qui sont énormément chers sur le site de l'enceinte.


Kardon Harman Citation One

- Weight 2 kg,

- Get answers to your questions,
- Listen to music (300 broadcasting services),
- Control your home automation .


Comparison


The factors which push you to buy such or such speaker are:

- The quality of the voice assistants and the compatible applications,
- The quality of the sound, the sound system and the amplification of the top -speaker or speakers,
- The design, the hands-free kit,
- An inexpensive speaker, at the lowest price.

In 2017, the 'Amazon's Alexa took first place in sales with 70% of the market while Google Home came in second with 23% of sales.

Since the start of 2018, another speaker is talked about, it is the Sony LF-S50G which has an irreproachable sound quality and other unprecedented functions.

The quality speakers, the best connected speakers, portable or not, are built around a Hifi amplifier of a few watts. They use 802.11b / g / n wifi or ac and the 2.4 Ghz and 5 Ghz frequency bands. They are sold with their hands-free kit.

All of them currently use state-of-the-art Alexa and Google voice assistants (OK Google, Bose Surround).

And finally, plug in its Hi-fi speaker is a plus. It allows you to create sound in the home by dialoguing thanks to its integrated assistant.


Invasion of privacy


We take here extracts from the article of the CNIL France (National Commission for Computing and Liberties) of 20/12/2018.


Etapes de fonctionement

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

- Step 1:
The user gives a command using a keyword,

- Step 2:
The keyword pronounced "wakes up" the speaker. Some speakers use voice biometrics, which means having the user record samples of their voice for one reason or another. These data are collected without the user's consent.

- Step 3:
The user provides his request. There are two possibilities:
. The requests are saved locally,
. The requests are sent to the cloud, that is to say to servers which keep a history of requests as well as the corresponding data (date, time, etc.),

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

- Step 5:
The loudspeaker is on standby.


Vigilant point

Three essential points must be observed in order not to harm your privacy. These 3 points of vigilance are:

- First point: Confidentiality of exchanges

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

. You should prefer a speaker equipped with a microphone activation and deactivation button,
. You have to mute the microphone or turn off the device when you don't want to be listened to,
. You must warn everyone around you at home,
. It is especially necessary to supervise the interactions of the children.

- Second point: The monetization of the ultimate

The enclosure is at the center of the life at home. Home life habits are discovered in the presence of the enclosure. The advice given by the committee is:

. You have to connect services that are really useful for you,
. You have to be vigilant for everything that is said in front of the device.

- Third point: The absence of a screen

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

. You must always go to the "dashboard" to delete the conversation history.
