Recognizer SET-PARAMS
The SET-PARAMS recognizer method, form the client to the server, tells the recognizer resource to set and modify recognizer context parameters like recognizer characteristics.
Many of the parameters in the SET-PARAMS method can also be used in another method like the RECOGNIZE 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 recognizer resource.
