lexicon Element PLS (Microsoft.Speech)

Specifies the highest level container for an XML-format lexicon document.

Syntax

<lexicon
   version = "1.0"
   xmlns = "http://www.w3.org/2001/06/grammar"
   alphabet = “ipa” | “x-microsoft-sapi” | “x-microsoft-ups”
   xml:lang = “(language code-country/region code)”
</lexicon >

Attributes

Attribute	Description
alphabet	Required. Specifies the default pronunciation alphabet to be used within the PLS document. The only acceptable values are ipa or x-microsoft-sapi or x-microsoft-ups. These values are case-sensitive and must be entered in lower case.
version	Required. Specifies the version number of the Pronunciation Lexicon Specification (PLS) Version 1.0 used. The only accepted value is 1.0.
xml:base	Optional. Specifies a lexicon document's base Uniform Resource Identifier (URI). The value for xml:base is used to resolve relative URIs in a lexicon document. Currently, only the contents of the metadata element can potentially use relative URIs.
xml:lang	Required. Declares the single language for the content of the containing lexicon document. The value can contain only a lower-case, two-letter language code, (such as "en" for English or "it" for Italian) or may optionally include an upper-case, country/region or other variation in addition to the language code. Examples with a county-region code include es-US for Spanish as spoken in the US, or fr-CA for French as spoken in Canada.
xmlns	Required. Specifies the XML namespace for W3C pronunciation lexicon. The XML namespace is “http://www.w3.org/2005/01/pronunciation-lexicon”.

Remarks

The pronunciation alphabet specified in the alphabet attribute may be overridden for a specific lexeme using the alphabet attribute of the phoneme Element PLS (Microsoft.Speech). You can also specify a phonetic alphabet programmatically for a speech recognition grammar, using the PhoneticAlphabet property.

See Phonetic Alphabet Reference (Microsoft.Speech) for more information about the phonetic alphabets that Microsoft Speech supports.

For a given language code declared in the xml:lang attribute, a speech engine that supports that language code must be installed for the lexicon to be loaded successfully.

If the xml:lang attribute specifies only a language code, and not a country/region code, (such as xml:lang="en"), then any installed speech engine that expresses support for that generic, region-independent language will be able to load the lexicon.

Example

The following example illustrates the use of the alphabet attribute of the phoneme element to specify a pronunciation using a different phonetic alphabet than the one specified by the alphabet attribute in the lexicon element, for a single instance of the word “hello”.

<lexicon version="1.0"
