Abstract interface for Prompting functionality. Prompts are handled as a series of audio segments, where segments may be paths to on-disk audio files or text, URIs to remote audio or text, in-memory binary audio, in-memory text for playback via a Text-to-Speech engine, or in-memory text for playback using concatenative audio routines (123 played as "1.ulaw 2.ulaw 3.ulaw").

The Prompt interface the handles prefetching, caching, and streaming audio as required to provide good response times and low CPU and network overhead.

There is one prompt interface per thread/line.
