This is determined by your chord library. Each set of letters is mapped to only a single output. For example, “thing” and “night” have the same five letters. However, the default chord for night is n+i+g+h, while the chord for thing is n+i+g+h+t. Context is taken into account for some combinations, though this is not yet fully customizable. For example, chording out after with will produce “without” rather than “with out”.
