AWS has made the Amazon Polly Generative engine update generally available for production use. It adds 14 voices across nine language variants. Generative voices for Hindi and Finnish are generally available for the first time. According to AWS, the update delivers more natural and expressive speech, more accurate pronunciation and low latency.

Existing generative voices are updated automatically. Voice names and API calls remain the same, and according to AWS, no code changes are needed. The company also states that there is no price increase or new billable item. Static speech output can be stored and replayed without additional charges.

The new voices are accessible through AWS Management Console, AWS CLI and AWS SDKs. The availability of a selected voice in a specific region can be checked by calling DescribeVoices. Audio samples are available to assess changes in quality.

What changed

Why it matters

The expanded language selection allows the same text-to-speech workflow to be used for more language variants in media, educational materials or customer service. Existing applications require no changes to their integration; the promised pronunciation improvements can be assessed using specific texts.
