Kaylee
======

Kaylee is a somewhat fancy speech recognizer that will run commands and
perform other functions when a user speaks loosely preset sentences. It
is based on `Blather <https://gitlab.com/jezra/blather>`__ by
`Jezra <http://www.jezra.net/>`__, but adds a lot of features that go
beyond the original purpose of Blather.

Requirements
------------

1. Python 3 (tested with 3.5, may work with older versions)
2. pocketsphinx 5prealpha
3. gstreamer-1.0 (and what ever plugin has pocketsphinx support)
4. gstreamer-1.0 base plugins (required for ALSA)
5. python-gobject (required for GStreamer and the GTK-based UI)
6. python-requests (required for automatic language updating)

**Note:** it may also be required to install
``pocketsphinx-hmm-en-hub4wsj``

Usage
-----

1. Copy options.json.tmp to ~/.config/kaylee/options.json and fill the
   "commands" section of the file with sentences to speak and commands
   to run.
2. Run kaylee.py. This will generate
   ~/.local/share/kaylee/sentences.corpus based on sentences in the
   "commands" section of options.json, then use the `Sphinx Knowledge
   Base Tool <http://www.speech.cs.cmu.edu/tools/lmtool.html>`__ to
   create and save a new language model and dictionary.

   -  For GTK UI, run kaylee.py -i g
   -  To start a UI in 'continuous' listen mode, use the -c flag
   -  To use a microphone other than the system default, use the -m flag

3. Start talking!

**Note:** default values for command-line arguments may be specified in
the options.json file.

Examples
~~~~~~~~

-  To run Kaylee with the GTK UI, starting in continuous listen mode:
   ``./kaylee.py -i g -c``

-  To run Kaylee with no UI and using a USB microphone recognized as
   device 2: ``./kaylee.py -m 2``

-  To have Kaylee pass each word of the matched sentence as a separate
   argument to the executed command: ``./kaylee.py -p``

-  To run a command when a valid sentence has been detected:
   ``./kaylee.py --valid-sentence-command=/path/to/command``

-  To run a command when a invalid sentence has been detected:
   ``./kaylee.py --invalid-sentence-command=/path/to/command``

Finding the Device Number of a USB microphone
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are a few ways to find the device number of a USB microphone.

-  ``cat /proc/asound/cards``
-  ``arecord -l``
