Why do you need a distributed system, i.e., a Thin Client?
A thick client has speech recognition and synthesis on the device. As resources available on a device shrink or the application requirements increase (larger application grammars) then the performance of the system becomes unacceptable. When that threshold is reached then it is economically feasible to distribute the speech over the network.
Grammar Size and Complexity
R Resources: memory and MIPS on the client device
G Size and Complexity of application grammars
R/G = 1 Resources are adequate to perform “real time”
recognition and synthesis.
