The SET-PARAMS synthesizer method, form the client to the server, tells the synthesizer resource to set and modify synthesizer context parameters like speech language.
Many of the parameters in the SET-PARAMS method can also be used in another method like the SPEAK method. If the server accepts these parameters, it will respond with a Status-Code of 200.
The following list describes the headers that can be used in conjunction with SET-PARAMS and GET-PARAMS for the synthesizer resource.

Note that for voice parameter selections and prosody options, LumenVox maintains default settings in the client_property.conf settings file as well as supporting SSML, which includes a rich set of formatting options, which is therefore recommended wherever possible.
