Using Prompt Files

Prompt files are infopkt files that contain many individual speech

phrases in a single file. Each phrase is a partial or complete prompt

in infopkt format followed by an INFOPKT_END_OF_SPEECH infopkt

with mode value 1. The prompt file starts with an
INFOPKT_PROMPT_MAP

infopkt, which contains file offsets to each

individual phrase.

The Bfv API contains functions that open and close a Brooktrout

prompt file and play individual phrases stored in it. For example,

after an application opens a Brooktrout prompt file, it can call the

BfvPromptPlay function to play any individual phrase, or it can

call the BfvPromptPlay function multiple times to concatenate

phrases and create a complete prompt.

Using Brooktrout prompt files provides two advantages. Since all of

the prompts are stored in a single file, tracking and maintaining

prompts is easier. And because you can combine phrases to create

complete prompts, you can reduce the amount of disk space needed

for overall speech storage.
