AWS account creation

When signing up for an AWS account, there is no specific fee just to register or create an account. The AWS account creation process is free, but you will need to provide payment information during the sign-up process as AWS services follow a pay-as-you-go model where you're charged only for the services you actually use.

The standard account creation process involves:

1. Going to https://portal.aws.amazon.com/billing/signup
2. Choosing between Business or Personal account type
3. Entering your personal or company information
4. Accepting the AWS Customer Agreement
5. Providing payment method information (required to proceed)
6. Verifying your phone number through a call or text message
7. Selecting an AWS Support plan
8. Completing the sign-up

Once your account is activated (which can take a few minutes but sometimes up to 24 hours), you'll have access to all AWS services including Amazon Lex.

If you're creating an account as an Amazon employee, you should check with your IT department or manager about the proper procedure, as there may be specific corporate accounts or internal processes for Amazon employees to access AWS services for work purposes. Some companies have policies regarding the use of corporate email addresses for external services, which could be relevant in your situation.
