An AWS Lambda function of an Alexa skill for virtual counseling / journal therapy. It asks you some open ended questions for you to reflect on yourself. It saves your answers to DynamoDB, and with a complementary MagicMirror module Magic Mirror Will See You Now, your logs will be analysed and the result will be displayed on your Magic Mirror.
- alexa-sdk (installed via
npm install)
To run this skill you need to do two things:
- deploy the code in Lambda
- configure the Alexa skill to use Lambda
- Go to the AWS Console and click on the Lambda link. Note: ensure you are in us-east or you won't be able to use Alexa with Lambda.
- Click on the Create a Lambda Function or Get Started Now button.
- Choose Blank Blueprint
- Choose trigger Alexa Skills Kit, click "Next"
- Name the Lambda Function, select the runtime as Node.js
- Go to the src directory, select all files and then create a zip file, make sure the zip file does not contain the src directory itself, otherwise Lambda function will not work.
- Select Code entry type as "Upload a .ZIP file" and then upload the .zip file to the Lambda
- Keep the Handler as index.handler (this refers to the main js file in the zip).
- Create a new role for full access of DynamoDB a. Go to the IAM service from the AWS Console b. Click on Roles, then Create New Role c. Call this Role lambda-dynamo-full-access-role d. Select AWS Lambda as the Role Type d. Select policies AmazonDynamoDBFullAccess and CloudWatchFullAccess (for debug) e. Click Next, then Create Role
- Go back to the Lambda console, Choose an existing role
- Choose lambda-dynamo-full-access-role
- Leave the Advanced settings as the defaults
- Click "Next" and review the settings then click "Create Function"
- Copy the ARN from the top right to be used later in the Alexa Skill Setup
- Go to the Alexa Console and click Add a New Skill.
- Set "Mirror Mirror On The Wall" as the skill name and "on the wall" as the invocation name, this is what is used to activate your skill. For example you would say: "Alexa, on the wall, say hello". If you customized the wake word as "Mirror mirror", you can say "Mirror mirror on the wall, find Snow White".
- Select the Lambda ARN for the skill Endpoint and paste the ARN copied from above. Click Next.
- Copy the Intent Schema from the included IntentSchema.json in the speechAssets folder.
- Copy the Sample Utterances from the included SampleUtterances.txt. Click Next.
- Go back to the skill Information tab and copy the appId. Paste the appId into the index.js file for the variable APP_ID, then update the Lambda source zip file with this change and upload to Lambda again, this step makes sure the Lambda function only serves request from authorized source.
- You are now able to start testing your Alexa skill! You should be able to go to the Echo webpage and see your skill enabled.
- In order to test it, try to say some of the Sample Utterances from the Examples section below.
- Your skill is now saved and once you are finished testing you can continue to publish your skill.
User: "Alexa, will you see me now?"
Alexa: "...."
If you are running AlexaPi on Raspberry Pi, or using a wake word engine like Snowboy, you can change the wake word from "Alexa" to "Magic Mirror", then you can say:
User: "Magic Mirror, ...."
Alexa: "...."
