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.
