The application is a software program that enables users to play and control music on a speaker device through voice commands. The application is designed to provide a simple and intuitive interface that allows users to play music and control playback on Spotify.

    The technologies, which are used:

• Java 17
• Porcupine Wake Word (https://picovoice.ai/docs/porcupine/)
• Rhino Speech-to-Intent (https://picovoice.ai/docs/rhino/)
• Cheetah Speech-to-Text (https://picovoice.ai/docs/cheetah/)
• Spotify API Library (https://github.com/spotify-web-api-java/spotify-web-api-java)

0. Keep in mind that before next steps you should have Spotify client installed on your system, in case your system is Raspberry pi you should have raspotify installed (https://github.com/dtcooper/raspotify)

1. Clone the repository

   git clone https://github.com/ABckh/Smart-Speaker.git
   

2. Go inside cloned repository

   cd Smart-Speaker/
   

3. Open example.properties, and you should replace everything which is in curly brackets:
   

     3.1   Replace {your_picovoice_access_key}, to do so:
           3.1.1.   Go to the Picovoice Console website: https://console.picovoice.ai/
           3.1.2.   If you don't have an account, click on the "Sign Up" button and create a new account. If you already have an account, log in.
           3.1.3.   Once you are logged in, you should see 'AccessKey' copy it and replace {your_picovoice_access_key} with your access key.
   

   picovoiceAccessKey={your_picovoice_access_key}
   

     3.2   Replace {your_platform} with one of the options: linux, mac, raspberry-pi

   rhinoContextPath=src/main/resources/rhino_contexts/Play-music-{your_platform}.rhn
   

     3.3 Replace {your_spotify_client_id} and {your_spotify_client_secret} with Spotify client id and Spotify client secret, to do so:

           3.3.5.   Once you have filled in the details, click on the "Create" button.
           3.3.6.   You will now see the details of your app, including the Client ID and the Client Secret. Copy these values and paste them.
   

   spotifyClientId={your_spotify_client_id}
   

   spotifyClientSecret={your_spotify_client_secret}
   

     3.4   Replace {your_spotify_device_id} with your Spotify device ID, to do so:

           3.4.4.   In the 'Response' copy id of the device needed and paste it to the example.properties file
   

   spotifyDeviceId={your_raspotify_device_id}
   

     3.5   Replace {your_spotify_refresh_token} with Spotify refresh token, to do so:
           3.5.1.   Go to the Spotify Web API Authorization Guide website: https://developer.spotify.com/documentation/general/guides/authorization-guide/
           3.5.2.   Follow the steps to obtain an Authorization Code.
           3.5.3.   Once you have obtained the Authorization Code, use it to make a POST request to the Spotify Accounts service to obtain a Refresh Token.
           3.5.4.   The Refresh Token should be returned in the response. Copy this value and paste it in example.properties
   

   spotifyRefreshToken={your_spotify_refresh_token}
   

4. Rename example.properties to config.properties

   mv example.properties config.properties
   

5. Install all the dependencies

   mvn clean install
   mvn compile 
   

6. Run the program:

   mvn exec:java
   

After everything is installed and the program is running, you can try it! The instruction how to use is written below!

1. Activate Picovoice: To activate Siri, simply say "Picovoice", after that you will see this message in the console:

Wake word is detected!

2. Give a command. All the possible commands are listed in Commands section.

3. That's it! Smart speaker will execute your command and print a messasge about it!

Important thing about commands: slash symbol (/) means or, also everything which is in brackets is optional to say and the programm will understand the context without them!
For example:
(please) pause/stop (music)
This command means that you can say either pause or stop and you can not say please and music at all!

  (please) pause/stop (music)
