Amazon upgraded the Generative engine behind Polly, its managed text-to-speech service, saying the new version produces more expressive and accurate speech at low latency. The upgrade adds 14 voices across 9 locales, including the first generally available Generative voices in Hindi and Finnish, bringing the catalog to 57 generative voices across 11 languages and 25 locales. Amazon says it is a drop-in change: voice names and API calls are unchanged, so existing applications keep working without code changes, and the upgrade happens in place for applications already using Generative voices. Region availability expands to AWS GovCloud (US-West), for a total of 11 AWS Regions. Amazon says the improved voice quality and accuracy come at the same pay-as-you-go price, with no cost increase, no new SKU and no changes to existing integrations, and cached static prompts can be replayed at no additional cost. The engine supports the SynthesizeSpeech API and the Bi-Di Streaming API StartSpeechSynthesisStream for real-time streaming, which Amazon says suits voice agents and game characters.
