Hey Athena

Overview

Your personal voice assistant. Written in Python.

"Hey Athena" is a 100% open-source, modular voice assistant framework. We aim to do everything that Siri, Cortana, and Echo can do - and more.

Usage Examples:

Say "Athena" (wait for double beep) then...

• "Play some music"
• "Text [Joe] [Wow, Hey Athena is so cool!]"
• "Tweet [Hello world!]" (IFTTT key required)
• "Define [artificial intelligence]"
• "Show me pictures of [Taj Mahal]"
• "Open facebook.com"

Write a simple "module" to control your house with your voice. See documentation: https://heyathena.com/docs/

Don't like the name "Athena"? Change it to anything you want, like "Joe" or "Swagger Bot".

Module Ideas

• Smart-Home Control
  • Power Outlets (Hook)
  • Thermostat (Nest)
• IFTTT Recipes (use Maker channel to trigger)
• Grades/Homework Assignments (see Canvas)
• Cooking Recipe Assistant (hands-free)
• Facebook, Twitter, GMail
• Timer/Stopwatch
• Calendar
• Games (Zork, etc.)
• Robot Movement

If you create a module, submit a pull request! We'd love to add it to the repository. You can also email it to [email protected]

Roadmap

Hey Athena is just getting started. We plan to build an open-source community built around a quality voice assistance framework. Here are some features you can expect to see in the future:

• Bigger Community: we are working on building a bigger open-source community
• Passive Modules: useful for voice/text notifications (e.g. - "You have an important unread email from Professor Valvano")
• Module Database: developers will be able to easily create and submit modules for other people to use
• Machine Learning: we are looking into libraries like Scikit to help Athena learn how to respond better
• Natural Language Processing (NLP): we are constantly working on improving NLP techniques with services like wit.ai

HTTP RESTful API

We are currently developing a cloud-hosted RESTful API (JSON) service. Users will be able to send HTTP requests and receive a voice/text JSON response.

Current: https://heyathena.com/api?q=test

Future: HTTP GET https://heyathena.com/api/{api_key}/q=list%20bitcoin%20price

Response: {"success": true, "response": "359.7", "intent": "bitcoin"}

How can I make my own Athena?

• Download and install Hey Athena using the directions below
• Write your own modules so Athena can respond to different commands
• Install Hey Athena on a Raspberry Pi to turn your house into a smart-home with voice control

Installation

For installation notes, please use: https://heyathena.com/docs/intro/install.html

How can I help?

• Write modules and contribute them by submitting a pull request to this repository
• Find errors and post issues
• If you modify the framework software, submit a pull request
• Give feedback and help us build a community!

Core Dependencies

• Python 3
• Pocketsphinx (SWIG required in your PATH during installation)
• SpeechRecognition
• Pyglet (AVBin required)
• PyAudio
• gTTS
• PyYAML
• Selenium

Active Modules

An active module is simply a collection of tasks. Tasks look for patterns in user text input (generally through "regular expressions"). If a pattern is matched, the task executes its action. Note: module priority is taken into account first, then task priority.

"""
File Name: hello_world.py
Finds and returns the latest bitcoin price

Usage Examples:
- "What is the price of bitcoin?"
- "How much is a bitcoin worth?"
    """

    from athena.classes.module import Module
    from athena.classes.task import ActiveTask
    from athena.api_library import bitcoin_api

    class GetValueTask(ActiveTask):

            def __init__(self):
                    # Matches any statement with the word "bitcoin"
                    super().__init__(words=['bitcoin'])

            # This default match method can be overridden
            # def match(self, text):
            #    # "text" is the STT translated input string
            #    # Return True if the text matches any word or pattern
            #    return self.match_any(text)

            def action(self, text):
                     # If 'bitcoin' was found in text, speak the bitcoin price
                    bitcoin_price = str(bitcoin_api.get_data('last'))
                    self.speak(bitcoin_price)

    # This is a bare-minimum module
    class Bitcoin(Module):

            def __init__(self):
                    tasks = [GetValueTask()]
                    super().__init__('bitcoin', tasks, priority=2)

Passive Modules

(soon-to-be implemented)

• Passive modules will be collections of scheduled/event-triggered tasks
• Useful for notifications (e.g. - Twitter, Facebook, GMail updates)

Athena APIs

An "Api" object is simply a separate library of functions for "Modules" to use. Athena stores a library of "Api" objects during runtime. Moreover, "Api" objects make it easy to load user configuration data at runtime. This is useful if your modules require username/password authentication (e.g. - logging into Spotify)
