A computerized system and method for modifying a pre-existing hypnotic script into a custom-made script for use in self-sedation by a user is disclosed. In one sense, the system can collect an input from a user specifying a desired time length and automatically adjust the playback length to accommodate the user by snippet selection and replacement from a collection of snippets stored in a memory. Snippet selection may be based on a variety of factors, which include a user's particular style preferences determined through an indirect analysis.
