<dd>This attribute will set the language of the speech synthesis for the request, using a valid <a href="http://www.ietf.org/rfc/bcp/bcp47.txt">BCP 47</a> language tag.
If unset it remains unset for getting in script, but will default to use the <a href="http://www.w3.org/TR/html5/elements.html#the-lang-and-xml:lang-attributes">lang</a> of the html document root element and associated hierachy.

<dd>The serviceURI attribute specifies the location of the speech synthesis service that the web application wishes to use.
If this attribute is unset at the time of the play method call, then the user agent <em class="rfc2119" title="should">must</em> use the user agent default speech service.
Note that the serviceURI is a generic URI and can thus point to local services either through use of a URN with meaning to the User Agent or by specifying a URL that the User Agent recognizes as a local service.
Additionally, the User Agent default can be local or remote and can incorporate end user choices via interfaces provided by the User Agent such as browser configuration parameters.</dd>
