Make changes in the skill code, deploy it, and test it on the device.

Modify the SSML in the skill, save it, and check Amazon CloudWatch for errors.

Edit the SSML in the skill and use the Alexa Simulator tab on the Test page of the developer console.

Use the Voice & Tone tab on the Test page in the developer console.

Manually extend the timeout so that users can input all the numbers.

The Lambda function is not executing fast enough. Double the currently specified Lambda memory

allocation in the Lambda basic settings section.

The default Lambda function timeout setting is too short and the Lambda function times out before the

response from the external API can be processed and a reply can be sent back to Amazon AlexA. Increase

the Lambda timeout limit.

There are too many concurrent Lambda functions running, causing the existing Lambda function to block

and then time out before a response can be returned to Amazon AlexA. Increase the Lambda function

reserve concurrency value to 30, then verify that the function can complete its work within 10 seconds.

There is a bug in the Lambda function code preventing the external API from being called. Enable Lambda

debugging and error handling and check Amazon CloudWatch Logs for the error, then modify the code

accordingly.

Use Amazon CloudFront to deliver content and cache the audio files across different geographical regions.

Migrate the sound files from Amazon S3 into Amazon Redshift to speed up the read operations.

Use Elastic Load Balancing to handle the traffic generated by the increasing number of users.

Enable cross-region replication on the Amazon S3 bucket policy to improve the skill’s performance.

Intents can have one built-in slot type only

All sample utterances within an intent should have both slots

SearchQuery is combined with another intent slot in an utterance.

“Dialog” is a reserved keyword in the Alexa Interaction Model schemA.

Ensure that the session ID provided by the request to Lambda is not already in use.

Rotate the Lambda ARN regularly to prevent others from using the service.

Retrieve the Application ID property from the request JSON and validate it against the Lambda

environment variables.

Provide the Lambda trigger with the Application ID so that it validates on the ask trigger.

Add AMAZON.FallbackIntent and respond with a message about baseball in the handler

Create a custom intent related to baseball, and when matched, provide a relevant response

Add more sample utterances related to baseball in the HowToPlayBasketball intent

Create a new custom baseball slot and add a slot-filling utterance to the HowToPlayBasketball intent.

Set shouldEndSession to false in the response object to prevent the skill from exiting.

Handle the SessionEndedRequest request type and persist the user’s session to a database.

Return false from the SessionEndedRequest handler so the session does not exist.

Return a reprompt in the response object from the SessionEndedRequest handler.
