Choosing an Amazon Polly voice
Amazon Polly offers four voice types:
- Standard — the original voices; cheapest, and the most widely available.
- Neural — more natural; the usual choice for IVR prompts and Lex bots.
- Long-form — tuned for reading long passages such as articles.
- Generative — the most expressive and human-sounding.
Not every voice comes in every type, and availability differs by AWS Region, so check the voice in the Region you deploy to.
In Amazon Connect
- Use a Set voice block early in the flow to choose language and voice; it applies to the rest of the contact until changed.
- Set the matching Lex bot locale and voice so the bot and the flow sound the same.
- Use SSML for pauses, emphasis, phone numbers and dates — the SSML builder generates the tags.
- For recorded prompts, convert audio with the audio prompt converter.
