Transcend Theory is a new Instrumental Trans Communication (ITC) tool developed for experimental spirit communication. It utilizes an alphabet list and digraphs to generate speech sounds believed to be influenced by spirits. The app features a Text To Speech (TTS) system to produce letter combinations, resembling a digital Ouija board for coherent messages.

The app offers a 'Play' mode for generating speech sounds, a 'Transcribe Mode' for converting sounds to text, and a 'Filter Mode' to reduce gibberish audio based on confidence scores. Users can adjust filter strength for varied message reception. Additional features include a Text Log, dark theme, reverb effect, and voice speed control.
