The author demonstrates voice control of a domestic vacuum-robot using an Arduino and Raspberry Pi. It’s an old saying that computers aren’t really smart, because they only do what we tell them to do. But now you can actually tell your Raspberry Pi to do something smart — to take control of connected devices in your home — using only your voice. It’s not hard — you can do it easily using some open source software and a Raspberry Pi. Just add an Arduino with an infrared (IR) LED and you can tell your Roomba what to do, too. Shall We Say a Game?
This project is made possible by years of research by scores of scientists, engineers, and linguists around the world working to enable real-time voice recognition that can run on modest hardware — the sort of advances that have brought us Siri on Apple devices and the voice recognition capabilities built into Google’s Android. Specifically, I’ll show you how to use an open source speech recognition toolkit from the at Carnegie Mellon University called, designed for use in embedded systems. This amazing library allows us to delegate the heavy lifting of turning sound into text, so we can focus on implementing higher-level logic to turn the text into meaningful actions, like commanding the lighting systems in your home and even your Roomba vacuum cleaner. It also allows us, as Makers, to get under the hood and experiment with aspects of a speech recognition engine that are usually reserved for those implementing the engines or studying them in academia. Preparing the Pi. For about $35, the Raspberry Pi, a credit-card-sized computer, has enough power to translate your spoken commands into computer commands for home automation and robotics.
Before you can use the Raspberry Pi for speech recognition, you need to make sure you’re able to record sound from your USB microphone. The Raspbian distribution is configured to use the Advanced Linux Sound Architecture (ALSA) for sound.
Despite its name this framework is quite mature and will work with many software packages and sound cards without alteration or configuration difficulties. For the specific case of the Pi there are a few tweaks we need to make to ensure that the USB card is preferred over the built-in audio.
First plug in your USB headset and power on the Pi. Once everything has finished loading, you can check that your USB audio is detected and ready to use by running the aplay -L command. This should display the name of your card such as in our example: Logitech H570e Stereo, USB Audio. If your USB sound card appears in this list then you can move on to making it the default for the system. To do this, use your favorite text editor to edit the alsa-base.conf file like so: sudo nano /etc/modprobe.d/alsa-base.conf.

A Philips Hue “bridge” for home automation Both the systems come with a networked “hub” or “bridge” which performs the work required to allow devices on the network, such as smartphones with the respective apps installed, to communicate commands to the lights. It turns out, both of these systems also have HTTP-based APIs which we can utilize for our example voice-controlled system. And both companies have developer programs that you can join to take full advantage of the APIs: » » For those who like to earn their knowledge a little more “guerrilla style” there are plenty of resources online that explain the basics of communicating with the hubs from both of these manufacturers.
Many tinkerers with published web articles on the subject learned their secrets through the age-old skills of careful inspection, network analysis, and reverse engineering. These skills are invaluable as a Maker and these systems both offer plenty of experience for those willing to work for it. The example project has a minimal set of Python commands that can be used to communicate with both the older Insteon 2242-222 Hub and the current Philips Hue bridge to get you started.
I Command Thee Robot. By including the IRremote library in your Arduino code, you can send raw infrared (IR) signals to command a Roomba. Once the IR hardware has been connected to the appropriate pins and the sketch compiled and uploaded through the Arduino IDE, you’re able to send commands over the serial connection that will be translated into something the Roomba can understand. Binary truly is becoming the universal language! All Together Now So there you have it, a complete system to control Insteon lights, Philips Hue lights, and an iRobot Roomba with nothing but the sound of your voice! Raspberry Pi (in black enclosure) + Arduino + infrared LED = complete hardware for yelling orders at your lights and robots.
This wouldn’t be possible without the generous contribution of the many open source projects we have used. This example project is also released as open source so that you can refer to it when implementing your own voice control projects on the Raspberry Pi and remix parts of it for your next project.
We can’t wait to see what you come up with — please tell us what you make in the comments below. Parts.

Everyone needs money but is there any safe and authentic way to do it online.

There are some credible sources but they require huge effort but little output I also struggled for almost 2 years to find something that I can do than this came into my knowledge I am doing this online work for two years. In start it was slow but with little time I settled in this.It is the nicest way to earn more and more money at home.$40h – $90hhow?
Part time or full time,I’ve been bringing in $82h It sounds unbelievable but you wont forgive yourself if you don’t check it out. Hello, I am very fascinated with this creation. I was wondering if you could email me what I should buy(I have nothing). I also wanted to know if this would work connected to my Dell Inspiron with Windows 7. And is there a way I can command the raspberry pi to tell the Arduino to turn on an LED and TURN off an LED of specific colors, and if you could email me how that would work.
I am learning how to program the 2 devices from nothing and I need to build this by February. Email: Thank you very much, Koosha Baf.
