# Synthesizing an SSML-enhanced document
<a name="example-ssml-synthesize-document"></a>

For longer input text, you may find it easier to save your SSML content to a file and simply specify the file name in the `synthesize-speech` command. For example you could save the following to a file called `example.xml`:

```
<?xml version="1.0"?>
<speak version="1.1" 
       xmlns="http://www.w3.org/2001/10/synthesis"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xsi:schemaLocation="http://www.w3.org/2001/10/synthesis http://www.w3.org/TR/speech-synthesis11/synthesis.xsd"
       xml:lang="en-US">Hello World</speak>
```

The `xml:lang` attribute specifies `en-US` (US English) as the language of the input text. For information about how the language of the input text and the language of the chosen voice affect the `SynthesizeSpeech` operation, see [Specifying another language for specific words](lang-tag.md). 

**To run an SSML-enhanced file**

1. Save the SSML to a file (for example, `example.xml`).

1. Run the following `synthesize-speech` command from the path where the XML file is stored and specify the SSML file as input by substituting `file:\\example.xml` for the input text. Because this command points to a file instead of containing the actual input text, you don't use quotation marks.
**Note**  
The following Amazon CLI example is formatted for Unix, Linux, and macOS. For Windows, replace the backslash (\\) Unix continuation character at the end of each line with a caret (^).

   ```
   aws polly synthesize-speech \
   --text-type ssml \
   --text file://example.xml \
   --output-format mp3 \
   --voice-id Joanna \
   speech.mp3
   ```

1. To hear the synthesized speech, play the resulting `speech.mp3` file using any audio player.
