A system for composing an audio-visual presentation over a communications network includes a composer system having a computer processor and associated memory and a telephone device, the composer system having a presentation containing at least one visual slide stored in the memory, and a host system including a computer processor and associated memory. The composer system: A. establishes a connection between the computer processor and the host system over a communications network and uploads the presentation to the host system over the communications network; and B. establishes a connection between the telephone device and the host system and records an audio narration clip for each of the at least one visual slide. The host system synchronizes each audio narration clip with its associated visual slide and stores the resulting audio-visual presentation in the memory of the host system.
