This paper presents an advanced platform for commercial use of speech technology products in multimedia applications. It covers the general concept of the hardware and software design of a powerful multi DSP communication board, based on the DSP32C processor, with an upgradable modular structure and universal port - one DSP processing one telephone line, and up to 16 DSPs simultaneously running different tasks on different channels on one board. A range of speech processing modules can be accessed through each port. They include TTS, SIR, SDR and SV and are provided by different speech technology suppliers. The paper gives information about the porting process and aids understanding the integration procedures of a single speech module into a complex UNIX based open system architecture.
