The World Wide Web Consortium (W3C) created Speech Synthesis Markup Language ([SSML](https://www.w3.org/TR/speech-synthesis11/)) as an XML-based markup language to assist in generating natural-sounding synthesized speech. The Plivo Speak XML element supports the generation of SSML-based speech, powered by [Amazon Polly](https://aws.amazon.com/polly/). It supports 27 languages and more than 40 voices, and allows developers to  control pronunciation, pitch, and volume. Here‘s how SSML appears within Plivo Speak XML elements: ```xml theme={null} Go Green, Go Plivo //Basic Text-to-Speech Go Green, Go Plivo //Text-to-Speech using SSML ``` To synthesize SSML speech on Plivo, specify one of the [Amazon Polly voices](https://plivo.com/docs/voice/concepts/ssml.md#ssml-voices) in the `voice` attribute of Plivo’s \ XML tag. Note that Polly voices must be namespaced with a `Polly` prefix. For example: ```xml theme={null} Go Green, Go Plivo ``` ## SSML tags You can use these SSML tags within Plivo XML. | SSML Tag | Action | Description | | - | - | - | | \ | [Add a pause](https://docs.aws.amazon.com/polly/latest/dg/supportedtags.html#break-tag) | Use this tag to include a pause in the speech. | | \ | [Emphasize words](https://docs.aws.amazon.com/polly/latest/dg/supportedtags.html#emphasis-tag) | Use this tag to change the rate and voice of the speech. | | \ | [Specify another language for specific words](https://docs.aws.amazon.com/polly/latest/dg/supportedtags.html#lang-tag) | Use this tag to set the natural language of the text. | | \

We expect to eventually charge for text-to-speech on the basis of the number of characters synthesized. ## SSML support in Plivo Server SDKs SSML tags are supported in all of our [Server SDKs](https://plivo.com/docs/sdk/server/). ## Example This example use the [Joey](https://d1.awsstatic.com/product-marketing/Polly/voices/joey.3abd7f17e6dae6c9248cacd7eb0ec910c691c4f4.mp3) voice for US English (en-US).
