About this project

From push buttons to e-panels, the development of technology keeps improving the way we interact with our surroundings. Since the advent of voice interaction technology, our life has truly become easier in many ways.

We think we can take advantage of this technology, and achieve more with it – ReSpeaker provides an open source, modular voice interface that allows us to hack things around us, just using our voices.

Rather than a voice assistant that fulfills simple tasks only when you asked, ReSpeaker provides a hands-free way of voice interaction for you and your surroundings. 

With ReSpeaker, you are able to control, or even communicate with your toy robot, your home appliances, your plant, your office, your internet-equipped devices and many other things in your daily life.

 

 

Powered by the MT7688 Wi-Fi module and the built-in high performance microphone, ReSpeaker responds to your voice and recognize your speeches based on powerful online cognitive services like Microsoft Cognitive Service, Amazon Alexa Voice Service, Google Speech API, Wit.ai and Houndify.

Also with the on board SD card slot to extend the storage and the integrated lightweight speech recognition engine - the PocketSphinx, ReSpeaker works equally well for keywords spotting when offline. You can have a large vocabulary and audio files stored in local storage to implement the speech recognition at anytime, anywhere, even without the internet.

Setting up ReSpeaker is super easy and only takes a few minutes.

Without any App installation, you can start by connecting ReSpeaker to your WiFi network and then directly use our Web-based App to access a range of rich featured applications that ReSpeaker has provided, includes music streaming, file manager, plug-in, customized settings and more.

Voice interface has never been apart from music entertainment, so does ReSpeaker. 

ReSpeaker supports Airplay/DLNA for wireless music streaming. Just connect ReSpeaker to any ordinary speaker with an AUX cable, then you can start enjoying the music you love without pressing a single button.

Of course we want to explore more possibilities coming out from ReSpeaker, and to achieve that we believe the best way is to leverage the power of the open source community. ReSpeaker runs the OpenWrt system that is based on Linux, which makes it 100% friendly to developers. 

And provided with our detailed and easy-to-use SDK, developers are able to develop more applications using Python on Linux. ReSpeaker also supports other popular programming languages like C/C++, Arduino, JavaScript and Lua.

ReSpeaker is not limited to what it can do for now, it is always growing. We’ve developed a plug-in system that would continuously expand ReSpeaker’s features and functionalities in the future. 

Our team will keep adding more plug-ins for ReSpeaker to cover as many things as possible that people want to have voice interactions with. 

Advanced users can also develop their own plug-ins using our user-friendly Python APIs. All the plug-ins will be shared on the Web APP and free-to-download for everyone.  

In addition to the plug-in system, ReSpeaker is also extendable with plug-n-play hardware add-ons. 

The far-field MIC Array allows your ReSpeaker to be able to recognize your location and hear you from across the room even while the music is playing. 

And the Grove extension board brings even more possibilities as you can connect various Grove sensors and actuators to extend its capabilities. The two onboard expansion headers also offer I2S, I2C, AUX, USB 2.0, GPIOs and many other interfaces that you can use for more applications.

You might wondering why ReSpeaker does not have speaker. In fact it does. We've cooperated with Meow King Audio Electronic Company and develop the Meow King Drive Unit. It can be directly connected to the bottom of ReSpeaker Core to produce beautiful sound out of it.

All the add-ons are modularized and have an identical disk design same as the core board. They can be stacked to one another when they are connected through soldering-free pins and header.

To improve the voice interaction experience, we developed the ReSpeaker Mic Array based on the XVSM-2000 Smart Microphone from XMOS. The board integrates 7 PDM microphones to help enhance ReSpeaker's acoustic DSP performance to a much higher level. With the Mic Array attached onto the top of the ReSpeaker Core, the Core is now able to: 

  • Hear You From Far Away
  • Focus On Your Voice
  •  Improve Your Voice Quality

 

The exposed PCB design does not mean ReSpeaker is just for people who knows a lot about hardware or software. 

The plug-in system is designed for the community to share and download their voice interactive projects as a simple plug-in to the ReSpeaker module. It has significantly simplified the use of ReSpeaker as anyone who has a ReSpeaker can install the plug-ins they want with a single click, and after that they can run voice interaction just like any others. 

Developers can of course achieve more with the SDK we provide to develop their own voice interaction projects .

For beginners, we have step-by-step tutorials and recipes to help you getting started with your first project with ReSpeaker.

 

We are making ReSpeaker compatible with our previous project the Wio Link and the subsequent members of the Wio family the Wio Node and the Wio Core.

Wio Link is an ESP8266 based open-source Wi-Fi development board to create IoT applications by virtualizing plug-n-play Grove modules to RESTful APIs with mobile APPs.

The introduction of the Wio family has truly brought what ReSpeaker can do to a higher level. 

Simply pair your ReSpeaker to your Wio product using our Web App, then you can have a voice interaction with any of your IoT devices that is built on Wio.

For each ReSpeaker Core reward it also comes with a 8G Class 10 Micro SD Card.
