She discovers some gaps in the default text-to-speech languages that CXone offers. Anne learns that with Cloud TTS Hub, she can choose a TTS provider that offers the languages she requires. She likes that the TTS providers offer a wide range of voices to choose from.

SSML Support

Cloud TTS Hub supports the use of Speech Synthesis Markup Language (SSML). SSML is an XML-based markup language that allows you to specify many aspects of how text is synthesized into speech. You can use it to fine-tune pronunciation, rate of speech, voice pitch, volume, and more.

To use SSML, text input must be:

  • Valid XML
  • Valid SSML
  • Contained within a set of <speak> </speak> tags

  • Marked up with tags that each have only one attribute (this includes the <speak> tag)

    <speak xml:lang="en-US">

    <voice name="en-US-JennyNeural"> Good morning Chris! </voice>

    <voice name="en-US-ChristopherNeural"> Good morning to you too, Jenny! </voice>

    </speak>

For example: 

<speak xml:lang="en-US">

Here are <say-as interpret-as="characters">SSML</say-as> samples.

I can pause <break time="3s"/>.

I can say cardinal numbers. This number is <say-as interpret-as="cardinal">1135</say-as>.

Or I can say ordinal numbers. You are <say-as interpret-as="ordinal">1135</say-as> in line.

I can even say numbers as digits. The digits are <say-as interpret-as="characters">1135</say-as>.

I can also substitute phrases, like the <sub alias="World Wide Web Consortium">W3C</sub>.

</speak>

You need to use the supported markup language from the TTS provider in your TTS scripts. Other TTS markup may not work. Refer to the Google TTS documentation for information about any SSML variations or requirements specific to Google.
