Amazon Alexa is a voice-controlled assistant virtuel[1] developed by Amazon. Conceived from the acquisition of Ivona in 2013, Alexa was officially introduced with the Amazon Echo in 2014. Alexa’s capabilities include setting timers, streaming music, and controlling various smart devices. It can also process voice commands to perform various tasks, such as ordering food or sending messages. Amazon has expanded Alexa’s reach, with Alexa now available in multiple languages and used in smart homes around the world. Despite its popularity, there have been concerns about vie privée[2] et security[3], particularly in terms of voice recordings. Amazon has addressed these concerns, offering users control over their recordings and ensuring that devices only stream recordings upon activation. Developers can create skills for Alexa using the Alexa Skills Kit and integrate Alexa into their devices using Amazon Voice Service.

Définitions des termes
1. assistant virtuel.
1 A Virtual Assistant, often abbreviated as VA, is a digital tool that uses artificial intelligence to perform various tasks and services. These tasks include, but are not limited to, answering queries, controlling devices, managing schedules, and more. The functionality of a VA is achieved through different interaction methods such as voice commands, text-based communication, and image recognition. Over time, continuous advancements in AI and natural language processing have significantly improved VAs, making them more sophisticated and user-friendly. Furthermore, VAs have found applications in a multitude of industries, where they are used for information retrieval, entertainment, customer support, and conversational commerce, among other things. Notable examples of VAs include Siri, Alexa, Google Assistant, and Bixby. They are integrated into various devices and operating systems, demonstrating their broad utility and reach.
2 Virtual assistants are a form of artificial intelligence (AI) that perform tasks and services for an individual, often based on commands or questions. The evolution of this technology began in the 1900s with early voice-activated devices. The application and capabilities of virtual assistants have significantly grown, ranging from managing emails to controlling home appliances. Notable examples include Siri, Alexa, Google Assistant, and Bixby. Advancements in AI and language models have revolutionized their conversation abilities, making interactions with users more human-like. However, their widespread use has also raised privacy, security, and ethical concerns. Despite this, they have economic significance and are integrated into various industries, driven by the adoption of Internet of Things (IoT). The global market for this technology is expected to exceed US$7.5 billion by 2024.
2. vie privée. La protection de la vie privée est un concept fondamental qui a évolué au cours de l'histoire et qui continue de façonner notre discours sociétal. Historiquement, il est issu de débats philosophiques, avec des figures comme Aristote et John Locke qui en ont posé les bases. La protection de la vie privée est également liée à des questions juridiques et éthiques, comme en témoignent les arrêts historiques de la Cour suprême et les révélations telles que celles d'Edward Snowden. Les progrès technologiques ont à la fois remis en question et renforcé la protection de la vie privée, en introduisant de nouvelles menaces et de nouvelles mesures de protection. Les normes de protection de la vie privée varient d'un pays à l'autre et d'une organisation internationale à l'autre. À l'ère numérique, la vie privée est confrontée à de nouveaux défis et considérations, tels que l'utilisation des médias sociaux, la culture du selfie et les services de géolocalisation. Ce concept englobe le droit d'un individu à garder ses informations personnelles secrètes et à l'abri de toute intrusion non autorisée.
Amazon Alexa (Wikipedia)

Amazon Alexa ou Alexa est un assistant virtuel technology largely based on a Polish speech synthesizer named Ivona, bought by Amazon in 2013. It was first used in the Amazon Echo smart speaker et le Echo Dot, Echo Studio and Amazon Tap speakers developed by Amazon Lab126. It is capable of natural language processing (NLP) for tasks such as voice interaction, music playback, creating to-do lists, setting alarms, streaming podcasts, playing audiobooks, providing weather, circulation, sports, other real-time information and nouvelles. Alexa can also control several smart devices as a home automation system. Alexa capabilities may be extended by installing "skills" (additional functionality developed by third-party vendors, in other settings more commonly called applications) such as weather programs and audio features. It performs these tasks using automatic speech recognition, NLP, and other forms of weak AI.
