Amazon Polly upgrades Generative engine with 14 new voices and Hindi, Finnish support

Amazon Polly has upgraded its Generative engine to provide more expressive, accurate, and low-latency speech output, adding 14 new voices across 9 locales. This upgrade is generally available in production and is a drop-in upgrade for existing generative voices, requiring no changes to voice names or API calls. New general availability includes Hindi (Arjun and Kiara) and Finnish (Suvi). The service is used for contact centers, LLM-based agentic applications, and media.
