Fresh hacks every day
[Ben Yeh] wrote in to tell us about this voice-controlled chess robot he built along with three others as a final project for their Georgia Tech ECE 4180 Embedded Systems Design class.
To handle the speech recognition they grabbed an EasyVR board. This is a fine solution because it prevents the need for a computer to process voice commands … Read the rest
Speech recognition is usually the purview of fairly high-powered computers chugging along at hundreds of Megahertz with megabytes of RAM. Bringing speech recognition to the low-power microcontroller you’d find in an Arduino sounds like the work of a mad scientist or Ph.D. candidate, but that’s exactly what [Arjo Chakravarty] did. He developed the μSpeech library for the Arduino to allow … Read the rest
It’s entirely possible to use a computer without the aid of a mouse or trackpad. Shift and arrow keys will get you very far, but that is entirely too taxing. [Stephen] came up with a really neat way to control a mouse with your voice, a project that is sure to find its way onto the desktops of those … Read the rest
[Youchun Zhang] and [Annie (Wei) Dai] found a way to differentiate vowel sounds using an ATmega644 as their final project for a microcontroller design class. Voice recognition is not out of the ordinary, but most of the time it uses a computer, smart phone, or specially designed hardware. This implementation uses an ATmega644, a microphone connected via an op-amp, and … Read the rest
Voice-controlled home automation doesn’t have to be wildly expensive if you have a little bit of time and some know-how to do the job yourself. [jjshortcut] wanted to control the lighting in his room without using physical switches. On his blog, he describes how he did it without spending a ton of money.
He picked up a VRBot speech … Read the rest
Last week, we posted a story about how to configure speech recognition at a beginner level. Several of the commenters expressed an interest in doing speech recognition for embedded devices. [Nickolay Shmyrev] volunteered to write some directions for those people. In this article, [Nickolay] will be taking you through the basics of setting up your embedded device with CMUsphinx… Read the rest
