1 Introduction

DA-GUI is a Web GUI that runs on top of a Flask Web Server.

For user interaction, it uses Amazon Polly for speech synthesis and Google Web API for speech recognition.

This implementation is in Icelandic. The code and comments are in English.

Acts like an echo bot, the server responses with the user's query.

2 Setup

Make sure to have Python 3.6 or newer installed.

2.1 Get virtualenv

$ pip3 install virtualenv

2.2 Create a virtual enviroment

Make sure to create a Python3 instead of Python2 enviroment by refrencing its binaries.

$ which python3
/usr/bin/python3

You can use any name you want, we will use "venv".

$ virtualenv -p /usr/bin/python3  venv

2.3 Activate enviroment

$ . venv/bin/activate

Now you have activated your virual enviroment and your teminal should display its name as so:

$(venv)

2.4 Install requried packages

$(venv) pip3 install -r requirements.txt  

2.5 Configuring the AWS CLI

Guide: Quickly Configuring the AWS CLI

$ aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-west-2
Default output format [None]: json

Tips

The standard aws configure adds a default profile instead of adminuser, so if you try to run server.py immediately after configuring AWS CLI you might get a botocore.exceptions.ProfileNotFound: The config profile (adminuser) could not be found error.

To fix this, you have to add an adminuser profile to your config file. On Linux or macOS, this is usually located at ~/.aws/config. On Windows, this is C:\Users\USERNAME \.aws\config

Simply add the following at the bottom of the file.

[profile adminuser]
region = INSERT REGION
output = INSERT JSON
aws_access_key_id = INSERT ACCESS KEY ID
aws_secret_access_key = INSERT SECRET ACCESS KEY

You can simply use the same values as those under the default user.

2.6 Run The Application

$(venv) python3 server.py

You’ll see output similar to this:

Serving Flask app "server"
Environment: development
Debug mode: on
Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Open the link in your Chrome browser.
