Google Home vs. Amazon Alexa : qui est le plus malin ?<\/a><\/h4>\n\n\n\n

\u2013 Zdnet.fr 2017 \u2013<\/em><\/p>\n\n\n\n

L’Amazon Echo a \u00e9t\u00e9 le premier appareil grand public utilisant le contr\u00f4le vocal pour activer des fonctions basiques, telles que la lecture de musique ou la recherche d’informations. Il a \u00e9t\u00e9 lanc\u00e9 aux \u00c9tats-Unis en 2015. Puis, en 2016, Google a commercialis\u00e9 son appareil concurrent, Google Home (qui arrive aujourd’hui en France).<\/p>\n\n\n\n

L’agence num\u00e9rique Stone Stone de Framingham, Massachusetts, a dress\u00e9 une lise de 5000 questions pour \u00e9valuer la pertinence de Google Home et Amazon Echo avec Alexa. Les 5.000 diff\u00e9rentes questions ont \u00e9t\u00e9 compil\u00e9es pour correspondre \u00e0 des \u00e9l\u00e9ments factuels du quotidien que les utilisateurs sont naturellement susceptibles de demander \u00e0 un assistant personnel ou de rechercher sur Google. Le m\u00eame ensemble de requ\u00eates avait \u00e9t\u00e9 utilis\u00e9 dans le test Google Home versus Amazon Echo.<\/p>\n\n\n\n

Il s’agissait de savoir si les assistants r\u00e9pondaient bel et bien et d\u00e9terminer la source de la r\u00e9ponse : \u00e0 partir d’une base de donn\u00e9es (comme le Knowledge Graph de Google) ou depuis une source tierce (\u00abselon Wikipedia\u00bb, etc.). Le test a \u00e9galement \u00e9valu\u00e9 \u00e0 quelle fr\u00e9quence chaque p\u00e9riph\u00e9rique n’a pas compris la requ\u00eate ainsi que les r\u00e9ponses incorrectes.<\/p>\n\n\n\n

Le test Stone Temple n’est pas exhaustif, l’objectif est de mesurer sur la capacit\u00e9 \u00e0 fournir des r\u00e9ponses directes \u00e0 des questions d’utilisateurs sp\u00e9cifiques. Il a test\u00e9 la capacit\u00e9 de chaque appareil \u00e0 fournir des r\u00e9ponses factuelles aux questions.<\/p>\n\n\n\n

R\u00e9sultat des courses : il y a des diff\u00e9rences de taille entre les deux dispositifs. Google Home a r\u00e9pondu \u00e0 bien plus de questions que son concurrent (3383 contre 1030) et semble plus pertinent. L’appareil de Mountain View a formul\u00e9 des r\u00e9ponses correctes dans 89,5% des cas contre 86,9% pour son concurrent. Les mauvaises r\u00e9ponses sont de 2,3% chez Google contre 6,3% chez Alexa. Pr\u00e9cisions qu’une requ\u00eate peut avoir plusieurs r\u00e9ponses possibles, en outre, l’appareil peut avoir r\u00e9pondu avec une blague.<\/p>\n\n\n\n

Google Home s’appuie d’avantage sur les r\u00e9sultats issus de sites tiers (un peu moins de la moiti\u00e9 des requ\u00eates), ce qui n’est pas le cas d’Alexa : 556 r\u00e9ponses dont 527 proviennent de Wikip\u00e9dia.<\/p>\n\n\n\n

A premi\u00e8re vue, Google Home semble \u00eatre un p\u00e9riph\u00e9rique plus intelligent. Avec l’acc\u00e8s au moteur de Google, cela n’est gu\u00e8re surprenant. Pour autant, Amazon Alexa n’a pas \u00e0 rougir \u00e9tant donn\u00e9 qu’il n’utilise pas la puissance de Google.<\/p>\n\n\n\n

Quelques mois plus tard, Stone Stone a renouvel\u00e9 l’exp\u00e9rience avec la m\u00eame m\u00e9thodologie. Et les m\u00eames r\u00e9sultats. Google Home a r\u00e9pondu \u00e0 la plupart des questions \u00e0 68,1%. Et 90,6% des questions auxquelles il a r\u00e9pondu, l’ont \u00e9t\u00e9 de mani\u00e8re absolument compl\u00e8te et correcte. Amazon Alexa a obtenu 87% de r\u00e9ponses correctes. Cependant, il n’a r\u00e9pondu qu’\u00e0 20,7% des questions pos\u00e9es.<\/p>\n\n\n\n

Le test a \u00e9galement fait des comparaisons avec Siri d’Apple et Cortana de Microsoft. Cette derni\u00e8re t n’\u00e9tait pas loin derri\u00e8re – avec 56,5% de r\u00e9ponses aux questions et 81,9% de r\u00e9ponses justes. Siri d’Apple s’en tire le plus mal avec 62,2% de ses r\u00e9ponses qualifi\u00e9es de compl\u00e8tes et correctes, pour tout juste 21,7% de r\u00e9ponses. Il sera int\u00e9ressant de voir comment la course aux assistants personnels \u00e9volue \u00e0 mesure que les fournisseurs d\u00e9veloppent leurs capacit\u00e9s et enrichissent leur logiciel.<\/p>\n","protected":false},"excerpt":{"rendered":"
