Boost your Alexa by making it respond as ChatGPT.
This repository contains a tutorial on how to create a simple Alexa skill that uses the OpenAI API to generate responses from the ChatGPT model.
Log in to your Amazon Developer account and navigate to the Alexa Developer Console.
Click on "Create Skill" and name the skill "Chat". Choose the primary locale according to your language.
Choose "Other" and "Custom" for the model.
Choose "Alexa-hosted (Python)" for the backend resources.
You now have two options:
- Click on "Import Skill", paste the link of this repository (https://github.com/k4l1sh/alexa-gpt.git), click "Import" and go directly to step 12
Or if you want to import the skill manually
- Select "Start from Scratch", click "Create Skill" and go to step 6
In the "Build" section, navigate to the "JSON Editor" tab.
Replace the existing JSON content with the provided JSON content:
{
"interactionModel": {
"languageModel": {
"invocationName": "chat",
"intents": [
{
"name": "GptQueryIntent",
"slots": [
{
"name": "query",
"type": "AMAZON.Person"
}
],
"samples": [
"{query}"
]
},
{
"name": "AMAZON.CancelIntent",
"samples": []
},
{
"name": "AMAZON.HelpIntent",
"samples": []
},
{
"name": "AMAZON.StopIntent",
"samples": []
},
{
"name": "AMAZON.NavigateHomeIntent",
"samples": []
}
],
"types": []
}
}
}
Save the model and click on "Build Model".
Go to "Code" section and add "openai" to requirements.txt. Your requirements.txt should look like this:
ask-sdk-core==1.11.0
boto3==1.9.216
requests>=2.20.0
Create an OpenAI API key by signing up and clicking in "+ Create new secret key" in the API keys page.
Replace your lambda_functions.py file with the provided lambda_function.py.

Put your OpenAI API key that you got from your OpenAI account
Save and deploy. Go to "Test" section and enable "Skill testing" in "Development".
You are now ready to use your Alexa in ChatGPT mode. You should see results like this:
Please note that running this skill will incur costs for using both AWS Lambda and the OpenAI API. Make sure you understand the pricing structure and monitor your usage to avoid unexpected charges.
