Making Linux Offline Voice Recognition Easier

September 25, 2021 by 10 Comments

For just about any task you care to name, a Linux-based desktop computer can get the job done using applications that rival or exceed those found on other platforms. However, that doesn’t mean it’s always easy to get it working, and speech recognition is just one of those difficult setups.

A project called Voice2JSON is trying to simplify the use of voice workflows. While it doesn’t provide the actual voice recognition, it does make it easier to get things going and then use speech in a natural way.

The software can integrate with several backends to do offline speech recognition including CMU’s pocketsphinx, Dan Povey’s Kaldi, Mozilla’s DeepSpeech 0.9, and Kyoto University’s Julius. However, the code is more than just a thin wrapper around these tools. The fast training process produces both a speech recognizer and an intent recognizer. So not only do you know there is a garage door, but you gain an understanding of the opening and closing of the garage door.

Speech Recognition For Linux Gets A Little Closer

January 17, 2018 by 33 Comments

It has become commonplace to yell out commands to a little box and have it answer you. However, voice input for the desktop has never really gone mainstream. This is particularly slow for Linux users whose options are shockingly limited, although decent speech support is baked into recent versions of Windows and OS X Yosemite and beyond.

There are four well-known open speech recognition engines: CMU Sphinx, Julius, Kaldi, and the recent release of Mozilla’s DeepSpeech (part of their Common Voice initiative). The trick for Linux users is successfully setting them up and using them in applications. [Michael Sheldon] aims to fix that — at least for DeepSpeech. He’s created an IBus plugin that lets DeepSpeech work with nearly any X application. He’s also provided PPAs that should make it easy to install for Ubuntu or related distributions.

You can see in the video below that it works, although [Michael] admits it is just a starting point. However, the great thing about Open Source is that armed with a working set up, it should be easy for others to contribute and build on the work he’s started.
