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 […]
Streaming Your Webcam w/ Raspberry Pi
[Last updated on Feb. 2. 2013 for (2012-12-16-wheezy-raspbian) Kernel Version 3.2.27+] Three years ago, we bought two small Webcams and since we wanted to use them on Linux and OS X, we went with the UVC and Mac compatible Creative LIVE!

Using a serial connection to connect to a Raspbery Pi has many advantages. The boot process (Kernel boot messages go to the UART at 115,200 bit/s) can be monitored, without the need to hookup an HDMI-Monitor. Once booted, you can of course login through a serial terminal as well, i.e. the serial connection allows logging-in […]
