AWS Polly InvalidVoiceIdException

The specified voice ID is not valid.

Understanding AWS Polly

AWS Polly is a cloud service that converts text into lifelike speech, allowing developers to create applications that can talk. It is part of Amazon Web Services and is widely used for creating voice-enabled applications. Polly supports a variety of languages and offers numerous voice options to suit different needs.

Recognizing the Symptom: InvalidVoiceIdException

When working with AWS Polly, you might encounter the InvalidVoiceIdException. This error typically occurs when the application attempts to use a voice ID that is not recognized by AWS Polly. The symptom is an error message indicating that the specified voice ID is invalid.

Details About the InvalidVoiceIdException

The InvalidVoiceIdException is an error code that signifies the use of an incorrect or unsupported voice ID in your AWS Polly request. This can happen if the voice ID is misspelled, deprecated, or not available in the region you are operating in. For a list of valid voice IDs, refer to the AWS Polly Voice List.

Steps to Fix the InvalidVoiceIdException

Step 1: Verify the Voice ID

Ensure that the voice ID you are using is correct and available. You can find a list of supported voices in the AWS Polly documentation. Double-check for any typos or case sensitivity issues.

Step 2: Check Regional Availability

Some voices may not be available in all AWS regions. Verify that the voice ID is supported in the region where your application is deployed. You can check regional availability in the AWS Regional Services List.

Step 3: Update Your Code

If you find that the voice ID is incorrect, update your application code to use a valid voice ID. Here is an example of how to specify a voice ID in a request:

{
"Text": "Hello, world!",
"VoiceId": "Joanna",
"OutputFormat": "mp3"
}

Step 4: Test Your Application

After making the necessary changes, test your application to ensure that the error is resolved. If the issue persists, consider reaching out to AWS Support for further assistance.

Conclusion

By following these steps, you should be able to resolve the InvalidVoiceIdException and ensure that your AWS Polly application functions smoothly. Always keep your voice IDs updated and verify their availability in your region to prevent similar issues in the future.
