Speech Development Cycle

7.3 Speech Development Cycle

A sample speech development cycle is shown in Figure 7–5. Some of the components, such as speech recording, speech analysis, speech editing, and speech evaluation, require different hardware and software. TI provides a speech development tool, called the SDS6000, which allows the user to perform speech analysis using various algorithms, speech editing for certain algorithms, and to evaluate synthesis results through playback of encoded speech. Design of the software and hardware, development of software, and prototype construction are all customer-dependent aspects of the speech development cycle.

7.4 Device Production Sequence

For the speech development group at TI to accept a custom device program, the customer must submit a new product release form (NPRF). This form describes the custom features of the device (e.g., customer information, prototype and production qualities, symbolization, etc.). Section 1 is completed by the customer and Section 2B is completed by the customer for package sales. Section 2A is completed by TI personnel. A copy of the NPRF can be found in section 7.6. Copies can be downloaded at www.ti.com/sc/speech.
