大耳朵。 亚马逊Dot是这家美国零售巨头推出的两款智能扬声器中尺寸较小的一款。尽管Alexa助理功能再测试中表现出色,但这台设备的功耗和数据安全都难以让人完全满意。

In review: Amazon Echo Dot
In review: Amazon Echo Dot

亚马逊Echo Dot是这家美国公司带来的实惠型家庭助理设备,归功于Alexa智能助理这台设备魅力十足。我们认为它的主要优势在于智能家电控制,用户将不再需要电源开关或智能手机操作。不过,语音控制有时也会十分尴尬,它需要设备提供适当的设置。

这款产品的其他功能也十分吸引人;不过将它放入一个已经完整的音响系统却十分困难。另外,希望用Echo听音乐的用户最好考虑尺寸更大的一款扬声器。在测试中,简单的管理操作,定时器和闹钟功能,以及语音书播放等功能都可以顺利使用。

亚马逊的Echo Dot和Alexa组成了一个强力的团队,不过它还需要在数据安全方面有所改进。

我们对亚马逊的Echo Dot最为不满的方面是数据安全。我们希望亚马逊在数据加密方面提供更多的信息,同时保证较高的数据保护标准。

亚马逊Echo Dot在这家零售巨头的产品线中占据了一个独特的位置。尽管它对于日常生活带来的额外价值并不是极大,但只需简单的一些更新,它将会为用户带来出色的娱乐性和对于智能家庭设备的便捷操控。
