Transcend Theory: This app is designed to generate random words. What the app does: The idea behind this app is to see if random formations of letters can create words and sounds of meaning. When you press the play button letters from an alphabet list will begin a random formation process at various lengths and intervals. These formations will be used to generate vocal sounds. Text transcriptions of these sounds can be used by turning on the Transcribe feature. The Filter feature of the app can be used to trim and "clean up" these audio clips to produce a more easily understandable interpretation. The result of this process will produce random words and vocal sounds. Settings: In the settings you will find a voice speed slider that can be used to speed up or slow down the voice sounds being produced. The reverb audio effect can be used to create a more spacious sound. A text log will store any text transcriptions you receive. The filter strength option of Low, Medium, and High will determine the amount of the audio segments that can be removed before regenerating a new audio clip. For entertainment purposes only.
