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 by Jezra, but adds a lot of features that go beyond the original purpose of Blather.

Requirements

  1. pocketsphinx
  2. gstreamer-1.0 (and what ever plugin has pocket sphinx support)
  3. gstreamer-1.0 base plugins (required for alsa)
  4. pygtk (only required for the Gtk based UI)
  5. pyyaml (only required for reading the options file)

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

Usage

  1. Move commands.tmp to ~/.config/blather/commands.conf and fill the file with sentences and command to run
  2. Run Blather.py, this will generate ~/.config/blather/sentences.corpus based on sentences in the ‘commands’ file
  3. Quit blather (there is a good chance it will just segfault)
  4. Go to http://www.speech.cs.cmu.edu/tools/lmtool.html and upload the sentences.corpus file
  5. Download the resulting XXXX.lm file to the ~/.config/blather/language directory and rename to file to ‘lm’
  6. Download the resulting XXXX.dic file to the ~/.config/blather/language directory and rename to file to ‘dic’
  7. Run Blather.py
    • For Gtk GUI, run Blather.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
  8. Start talking

Note: to start Blather without needing to enter command line options all the time, copy options.yaml.tmp to ~/.config/blather/options.yaml and edit accordingly.

Bonus

Once the sentences.corpus file has been created, run the language_updater.sh script to automate the process of creating and downloading language files.

Examples

  • To run blather with the GTK UI and start in continuous listen mode: ./Blather.py -i g -c

  • To run blather with no UI and using a USB microphone recognized and device 2: ./Blather.py -m 2

  • To have blather pass the matched sentence to the executing command: ./Blather.py -p

    explanation: if the commands.conf contains: good morning world : example_command.sh then 3 arguments, ‘good’, ‘morning’, and ‘world’ would get passed to example_command.sh as example_command.sh good morning world

  • To run a command when a valid sentence has been detected: ./Blather.py --valid-sentence-command=/path/to/command note: this can be set in the options.yml file

  • To run a command when a invalid sentence has been detected: ./Blather.py --invalid-sentence-command=/path/to/command note: this can be set in the options.yml file

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
