Project description

code-climate-image circle-ci-image codecov-image gemnasium-image

Alexa client in your browser. Django app. Talk to Alexa from your desktop, phone, or tablet browser.


Dependencies

This project depends on: - django-channels. - Snowboy

Install and configure those first.

Snowboy

Snowboy detects when the wakeword “Alexa” is uttered.

You must compile Snowboy manually. Copy the compiled snowboy folder to the top level of you project. By default, the folder structure should be:

.
├── ...
├── snowboy
|   ├── snowboy-detect-swig.cc
|   ├── snowboydetect.py
|   └── resources
|       ├── alexa.umdl
|       └── common.res
└── ...

If the default folder structure does not suit your needs you can customize the wakeword detector.

Installation

pip install alexa_browser_client

Add alexa_browser_client to your settings INSTALLED_APPS.

Routing and urls

Customization

Wakeword

The default wakeword is “Alexa”. You can change this by customizing the lifecycle’s audio_detector_class:

# my_project/consumers.py

import alexa_browser_client
import command_lifecycle


class CustomAudioDetector(command_lifecycle.wakeword.SnowboyWakewordDetector):
    wakeword_library_import_path = 'dotted.import.path.to.wakeword.Detector'
    resource_file = b'path/to/resource_file.res'
    decoder_model = b'path/to/model_file.umdl'


class CustomAudioLifecycle(alexa_browser_client.AudioLifecycle):
    audio_detector_class = CustomAudioDetector


class CustomAlexaConsumer(alexa_browser_client.AlexaConsumer):
    audio_lifecycle_class = CustomAudioLifecycle

Then in your routes.py:

from my_project import consumers


channel_routing = [
    consumers.CustomAlexaConsumer.as_route(path='/'),
]

Unit test

To run the unit tests, call the following commands:

pip install -r requirements-dev.txt
./scripts/tests.sh

To test a specific file, call the following command:
