The Amazon Echo has been a big success for its decent music experience and most importantly the Alexa voice interaction service. People who loves music as well as enjoy controlling smart devices with their voices would definitely want one. But the truth is, many of us already have a speaker for music playing, and the only problem is that, it is not as smart as Echo.

The ReSpeaker from Seeed Studio was just launched on Kickstarter in August. It is a hardware module that uses existing voice recognition services like Amazon’s Alexa Voice Service, the Google Speech API, the Microsoft Cognitive Service, and Houndify to allow voice interaction with anything you want. The ReSpeaker also comes with a far-field voice capture microphone array which means it is able to hear you as well as expensive hardware like the Echo.
