Setting media (MIME) types

Nuance configurations use MIME types to define media types.

Speech Server supports file extension rules that determine the MIME type of a request if a client application does not supply a type. These rules may be specified via the Management Station using parameters of the form:

server.inet.extensionRule.extension VXIString mime-type

Where the extension varies. You can add rules for additional types, but note that Speech Server does not understand all possible MIME types.

Set the following MIME type associations on your web server.

• To set associations on Apache, edit the file ApacheRoot/conf/mime.types.
• To set associations on Tomcat, add each association to the "Default MIME Type Mappings" section of the file TomcatRoot/conf/web.xml.

For Nuance Recognizer, add the following associations:

Extension	MIME type
gram	application/x-swi-grammar
grxml	application/srgs+xml

For Vocalizer, add the following associations:

Extension	MIME type
alaw	audio/x-alaw-basic
bdc	application/edct-bin-dictionary
dcb	application/edct-bin-dictionary
dct	application/edct-text-dictionary
html	text/html
L16	audio/L16;rate=8000
mulaw	audio/basic
sdc	application/sdct-bin-dictionary
ssml	application/synthesis+ssml (preferred by Nuance) application/ssml+xml (allowed)
tdc	application/edct-text-dictionary
type	Specifies the scope when loading a dictionary for text normalization. The value of scope is any text normalization type or arbitrary string representing. When the application specifies the scope (with the TN escape sequence) in spoken text, Vocalizer activates any dictionaries loaded with that scope. This example defines two scopes for a dictionary: application/type=sms,biking
ulaw	audio/basic
wav	audio/x-wav
xml	text/srgs+xml
