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
