Alexa virtual device

Alexa Device

This project allows to launch Alexa on any Linux devices, even on embedded devices like Raspberry Pi (with usb headset).

Running

• Follow this manual to create your own device and security profile - https://github.com/alexa/avs-device-sdk/wiki/Create-Security-Profile
  Add http://alexa.local:3000/authresponse to Allowed Return URLs and http://alexa.local:3000 to Allowed Origins Note this step can be skipped if you already have device profile credentials.
• Install dependencies

sudo apt install python3-pip git ffmpeg swig libportaudio2 portaudio19-dev libpulse-dev
sudo pip3 install requests 'git+https://github.com/moaxey/python-zeroconf' pocketsphinx pyaudio

Note 'libpulse-dev' should be installed only for PulseAudio based devices. 'pyaduio', 'libportaudio2' and 'portaudio19-dev' should be installed on other devices, for example alsa capable.

• Make sure your system has PulseAudio support.
• Run

python3 alexa.py

• Open http://alexa.local:3000 in web browser on local device or device in the same network. Note app provides mDNS advertisement of local domain alexa.local. This is very helpful for using with monitorless devices.
• Fill device credentials which was created in step 1, click 'log in'. Note Voice detection threshold is float value for adjusting voice detection. The less value, the easier to trigger. You may need to adjust it for your mic and voice.
• Fill your amazon credentials.
• Now you can speak with Alexa. App uses voice activation. Say 'Alexa' and phrase that you want to say to her. App makes beep in speakers when it hear 'Alexa' keyword and start recording.

Snap package ( https://www.ubuntu.com/desktop/snappy )

App can be built as snap package. Install pulseaudio snap before installing this:

sudo snap install --devmode pulseaudio

Now build and install:

cd snap
snacraft
sudo snap install --devmode alexa_1.0_amd64.snap

Note if you modified snap to used for alsa based devices, then additionally call this line sudo snap connect alexa:alsa :alsa.

alexadevice's Issues

alexa snap fails to establish listening port

Using alexa (beta) 1.1 from 'data-art' on Ubuntu 17.04 x86_64.

Using these snap install instructions, I received an info message during install, and saw no listening port 3000 subsequent to the install. I'm quite new at snap usage, so this may be an error on my part.

Allowed Return URLs and Allowed-Origins must use HTTPS protocol

It is not possible to "Add http://alexa.local:3000/authresponse to the Allowed Return URLs and http://alexa.local:3000 to the Allowed-Origins."

http protocol is not accepted, it must be https.

please stop using snap

Snap pollutes the user's environment and is generally unacceptable for a packaging solution.
I can defend this in the chance it is not already painfully obvious.

Please use rpm's and deb's.
