Class Emphasis

java.lang.Object
  org.jvoicexml.xml.XmlNode
      org.jvoicexml.xml.vxml.VoiceXmlNode
          org.jvoicexml.xml.ssml.Emphasis

All Implemented Interfaces:

XmlWritable, Node

public final class Emphasis
extends VoiceXmlNode

The emphasis element requests that the contained text be spoken with emphasis (also referred to as prominence or stress). The synthesis processor determines how to render emphasis since the nature of emphasis differs between languages, dialects or even voices.

Field Detail

TAG_NAME

public static final String TAG_NAME

Name of the tag.

Constant Field Values

ATTRIBUTE_LEVEL

public static final String ATTRIBUTE_LEVEL

The optional level attribute indicates the strength of emphasis to be applied. Defined values are "strong", "moderate", "none" and "reduced". The default level is "moderate". The meaning of "strong" and "moderate" emphasis is interpreted according to the language being spoken (languages indicate emphasis using a possible combination of pitch change, timing changes, loudness and other acoustic differences). The "reduced" level is effectively the opposite of emphasizing a word. For example, when the phrase "going to" is reduced it may be spoken as "gonna". The "none" level is used to prevent the synthesis processor from emphasizing words that it might typically emphasize. The values "none", "moderate", and "strong" are monotonically non-decreasing in strength.

ATTRIBUTE_NAMES

protected static final ArrayList<String> ATTRIBUTE_NAMES

CHILD_TAGS

private static final Set<String> CHILD_TAGS
