PollyEngine

type PollyEngine = "neural" | "generative" | "long-form" | "standard";

Defined in: src/providers/tts/polly/PollyTTS.ts:42

Amazon Polly synthesis engines.

Remarks

• 'neural' — Neural TTS voices, high quality (default)
• 'generative' — Most human-like, generative voices
• 'long-form' — Optimized for long-form content (articles, training)
• 'standard' — Legacy concatenative voices, lowest cost

Each voice supports a subset of engines — see the Polly voice list.
