Echo, Amazon's answer to Siri, is a speaker that listens to you

On Thursday, Amazon announced the Echo: a personal assistant in the form of a speaker. The $199 Amazon Echo can play music, take dictation, tell jokes, and read news summaries.

A home-theater speaker that鈥檚 also a personal assistant? It seems like an unlikely combination, but that鈥檚 what Amazon is offering in the , a 9-inch-tall, tube-shaped device that plays music, responds to voice commands, and (of course) allows you to add items to your Amazon shopping cart.

The Echo, which sells for $199 (or $99 for Amazon Prime members), is more or less Amazon鈥檚 response to Siri. It鈥檚 always on, but is only activated when you say a 鈥渨ake word鈥 (the shows a family using the word 鈥淎lexa,鈥 but doesn鈥檛 make it clear whether you can pick your own wake word). The Echo is connected to the Internet, so it can read news reports, look up bits of information, or stream music from Spotify or Pandora.

The Echo has seven microphones and incorporates Amazon鈥檚 far-field technology, meaning that you shouldn鈥檛 have to raise your voice to interact with it. It also has noise-filtering built in, so you can interact with the Echo even while it鈥檚 playing music. The company also says the Echo will learn your speech patterns and vocabulary over time, so it should get more helpful the longer you use it.

The promo video makes the Echo seem very pleasant: Alexa鈥檚 voice has a fairly realistic cadence, and it can respond to a wide range of queries (including playing specific music playlists and even telling jokes). It also has a 2.5-inch woofer for bass and a 2-inch tweeter for high pitches, which should make for good-quality audio.

The Echo uses the same cloud backend as other Amazon Fire devices, which is probably an indication that the company is confident in its voice-search technology and wants to put it to use in more devices. The company is releasing a companion app, as well, to allow users to interact with the Echo on their phones. There鈥檚 no standalone Echo app, however, which seems like a missed opportunity: if the cloud service works well, more people would likely be interested in using it on their phones than in having to pay nearly $200 for a separate device that must be plugged into the wall.

In any case, Amazon is taking a very careful approach to the Echo鈥檚 launch: customers must apply for an invitation to buy one, and only limited numbers of devices will be shipped out at first. This may be a way for the company to gauge customer interest and make sure that the Echo鈥檚 real-world performance measures up to its promise.
