Tools for Building Asynchronous Servers to Support Speech and Audio Applications

Distributed clientisewer models are becoming increasingly prevalent in multimedia systems and advanced user interface design. A multimedia application, for example, may play and record audio, use speech recognition input and use a window system for graphical I/O. The software architecture of such a system can be simplified if the application communicates to multiple servers (e.g., audio servers, recognition servers) that each manage different types of input and output. This paper describes tools for rapidly prototyping distributed asynchronous servers and applications, with an emphasis on supporting highly interactive user interfaces, temporal media, and multi-modal UO. The Socket Manager handles low-level connection management and device I/O by supporting a callback mechanism for connection initiation, shutdown, and for reading incoming data. The Byte Stream Manager consists of an RPC compiler and rnn-time library that supports synchronous and asynchronous calls, with both a programm...
