Polly - Support long text

The speech generation service has been enhanced to support longer text inputs, ensuring smoother and more natural audio output.

What’s new

• Speech requests can now exceed the previous character limit
• Longer text is automatically broken into natural-sounding sections
• The final result is still delivered as a single audio file

Impact

• Longer messages can be converted into speech without being cut off
• Audio playback remains seamless, with no pauses or interruptions
• No changes are required on the front end or in existing integrations

Allow Application Keys to Be Assigned to Long-Lived Tokens (LLT)

You can now choose which application an access token belongs to when creating long-lived tokens.

Previously, long-lived tokens were always linked to the default application, which could cause issues when using them across different apps. This update gives you more flexibility and ensures tokens are correctly associated with the application they’re intended for.

What’s new

• Better control over how tokens are used in different applications
• Fewer access and permission issues in production environments
• No change if you’re already using the default setup

No action is required unless you want to take advantage of this new option.

Session is deleted when a request uses a different application key (Error 114)

We’ve fixed an issue where a session could be ended unexpectedly if a request was made using the wrong application key.

Now, if this happens, you’ll simply see an error message and your session will remain active. This prevents sessions from being closed accidentally and improves overall reliability.

No action is required from users.

New metrics charts for webhooks

Webhook monitoring has been enhanced with visual metrics to make performance and activity easier to understand at a glance.

• Each webhook now includes its own metrics chart
• Activity data are displayed in a clear, visual format
• No configuration is required to access the new charts

Impact

• Faster insight into webhook behaviour and reliability
• Easier troubleshooting
• No changes to existing webhooks
