The idea behind the Vocal-Emotion Lamp is rather simple: to use a small affordable computer that can continually recognize emotion from the human voice and then visualize the result of the analysis, effortlessly and enjoyably. The implementation of this idea uses the small and inexpensive Raspberry Pi computer, extended with a far-field microphone expansion board. The software that performs […]

Raspberry Pi – Translator
Recently, I described how to perform speech recognition on a Raspberry Pi, using the on device sphinxbase / pocketsphinx open source speech recognition toolkit. This approach works reasonably well, but with high accuracy, only for a relatively small dictionary of words. Like the article showed, pocketsphinx works great on a Raspberry Pi to do keyword […]
Raspberry Pi 2 – Speech Recognition on device
This is a lengthy post and very dry, but it provides detailed instructions for how to build and install SphinxBase and PocketSphinx and how to generate a pronunciation dictionary and a language model, all so that speech recognition can be run directly on the Raspberry Pi, without network access. Don’t expect it to be as […]
Extended list of 8-bit AVR Micro-Controllers, easily programmable with the Arduino IDE
A couple days back, I wrote about ‘The $3 Arduino‘, how to leave the Arduino board behind and program an ATmega168 Micro-Controller directly, still using the Arduino IDE but with the AVRMSPII programmer. Of course, the ATmega168 isn’t the only MC available for something like that. In fact, I have quite a few 8-bit AVR […]
The $3 Arduino
Buying and using an official Arduino Board like the standard Arduino Uno is the perfect way to get started with the Arduino language, common electronic components, or your own embedded prototyping project. However, once you have mastered the initial challenges and have built some projects, the Arduino Board can get in the way. For instance, […]
