Amazon Polly upgrades its Generative engine: 14 new voices across 9 locales, with the same API and the same price
A voice upgrade that takes effect without a code change. What changed, and why no code change is a reason to regression-test.
// Key points
- The upgraded Generative engine produces more natural, more accurate speech with low-latency streaming, and adds 14 voices across 9 locales, including generative voices in Hindi and Finnish for the first time.
- It's a drop-in upgrade for existing generative voices: voice names and API calls are unchanged, so existing applications keep working.
- Pricing is unchanged with no new SKU, and synthesized static prompts can be cached and replayed at no extra cost.
Builder's takeA drop-in upgrade means your production voice has already changed under you. For a voice product like AI Interview, I'd re-listen to a few fixed scripts that read out IDs, names and jargon, and keep them as an audio baseline; fixed prompts like the opening line can switch to cached replay, which is cheaper and more consistent.
