EVM Systems

TI's development and emulation systems support the writing and debugging of assembly language programs for speech processors. Each consists of emulation hardware, an assembler and EVM interface programs for DOS-based computers.

WinSDS System

The WinSDS is a speech development system (SDS) which runs on a 486 or Pentium™ class computer running Windows version 3.11 or Windows 95. It provides rapid and convenient collection and analysis of speech, with numeric and graphical editing all with menu driven windows which can be accessed by mouse or keyboard. It also allows a speech editor to evaluate various levels of compression to achieve the best possible quality while using the least memory. The system consists of a proprietary DSP coprocessor board with an editing software package.

System Emulator Boards

TI offers several system emulator boards (MSD50C1x, SEB60C20) to help you develop systems using TI speech synthesizer chips. Each is a single board system that includes a target cable, switches for mask options, sockets for EPROMs, and a special speech synthesizer chip. Instead of internal ROM, these chips have data and address lines to interface with external memory systems (EPROMs).

Once a program is developed on the EMU system and burned into EPROM, the programmed EPROMs can be installed in the emulator board sockets and the target cable plugged directly into the target system's speech synthesizer chip socket. The emulator board then emulates the behavior of the factory programmed speech synthesizer chip. This creates a compact unit for demonstration, field testing, and program verification without expense and lead time of mask generation.

Microprocessor Code Development

Since microprocessor code is specific to the application, users often prefer to generate and test it. However, TI stands ready to help with code development or to provide lists of capable third parties. TI also supplies synthesis software and other algorithms which may be incorporated into the customer's TSP50C0x/TSP50C1x/MSP50C3x program.

Vocabulary Development

Custom speech may be developed to fit the specific needs of the final product. TI has developed broad expertise in both the aesthetic and technical area of custom speech development.

In close cooperation with our customers, we can select speakers, develop scripts, and record the speech on digital tape. Our analysts can process the speech and edit it to achieve pleasant, realistic energy levels and pitch. Then we can compress the speech data into LPC format ready for use in your system.

TI also can provide a list of side companies qualified to help with custom speech development and engineering support.
