SSML reference

The Speech Synthesis Markup Language (SSML) is an XML-based markup language for speech synthesis. Its essential role is to provide authors of synthesizable content a standard way to control aspects of speech such as pronunciation, volume, pitch, rate, etc. across different synthesis-capable platforms.

Note that not all of the elements and options described in the W3 SSML specification are currently supported by all SDKs. This page details which elements are available for each SDK.

Reserve characters

Avoid using SSML reserve characters in the text that is to be converted to audio. When you need to use an SSML reserve character, prevent the character from being read as code by using its escape code. The following table shows reserved SSML characters and their associated escape codes.

Markups

Audio VSDK-CSDK VSDK-BARATINOO

Audio SSML Markup is used to insert a recorded audio file. If the audio file cannot be retrieved, the element's contents are synthesized. The content is the fallback text used when the audio file is not supported.

Example:

XML
<audio src="file:laugh">
  haha
</audio>

Attribute

Description

src

The URI of a document with an appropriate MIME type. URIs may be absolute or relative to the base:uri specified in <speak> element. Audio files may be local (file://, or absolute paths) or remote (http://).

Supported audio files:

Lang VSDK-CSDK VSDK-BARATINOO

Lexicon VSDK-BARATINOO

Lexicon SSML markup is used to reference a lexicon document.

VSDK-BARATINOO

Attribute

Description

Attribute

Description

ref

The ref attribute specifies a name that references a lexicon document as assigned by the xml:id attribute of the lexicon element.

Mark VSDK-BARATINOO

The mark element specifies a named event which is triggered by the TTS engine when that location in the text is encountered in the generated audio stream. (What effect this event has is application specific, but it doesn’t affect the audion being generated)

The mark event must have a name attribute. The given name doesn’t have any meaning to the TS engine, but is included in the generated event.

Note that built-in normalization rules might, in some particular contexts such as date and currency expressions, cause adjacent words and numbers to be reordered. The TTS engine will generally try to preserve the association between marks and adjacent words in such cases, meaning that the mark events are not necessarily triggered in the exact order in which they occur in the SSML input but rather in a way that is more true to the reading order.

Example:

XML
<mark name="item1"/>First item, <mark name="item2"/>second item.

Attribute

Description

name

Marker name

vox:typeVSDK-BARATINOO

Value

Description

sync (default)

The voice synthesis engine will trigger an event when that location in the text is encountered in the generated audio stream.

wait

A wait marker allows rendering of the audio signal to be deferred until the duration of the immediately following content has been determined. The end of the content whose duration is to be determined is marked by either the end of the root <speak> element or a <mark> element, of any type, that bears the same name (case-sensitive).
For example:

XML
Text before…
<mark name="foo" vox:type="wait"/>
piece of text
<mark name="foo"/> 
Text after…

When Baratinoo processes the above markup, notification is first made by a WAITMARKER event with the name foo and the duration in samples of the rendered content piece of text. Then the signal for the piece of text is sent, and finally, notification is made by a MARKER event with the name foo, signaling the end of the marked sequence.
It is possible to set another <mark>, of any type, before the end of the deferred content is encountered.

Paragraph VSDK-CSDK VSDK-BARATINOO

Paragraph SSML markup is used to indicate a paragraph in your text.

processorchoice

The synthesis processor chooses the behavior (either changevoice, ignoretext, or ignorelang).
