Python-Listen

Version 0.0.2

This project is still only in the early stages, but it aims to present an intuitive interface for background listening and speech to text using CMUSphinx's gstreamer plugin on Linux.

• See /source/sphinxwrap.py for module
• See /source/sphinxwrap.pyc for precompiled module
• See /source/basic demo.py for a demo

This module has only been tested on Ubuntu, but may work on other Linux distributions.

To import the module:

  import sphinxwrap

To create an instance of the listener use:

  sphinxwrap.backgroundListener(<OPTIONAL: audio source, defaults to "alsasrc">)

To add a particular word to listen for use the add method:

  .add(<a word of type str>, <event callback>)
  # returns True is successful
  # raises ValueError if the word is not of type str
  # rasies ValueError if the callback cannot be called

To stop listening for a particular word use the remove method:

  .remove(<a word of type str>)
  # returns True is successful, False otherwise
  # raises ValueError if the word is not of type str

To start listening call the startListening method:

  .startListening()

To stop listening call the stopListening method:

  .stopListening()
