The invention discloses an AI control interaction system for a singing music fountain. The AI control interaction system comprises a wireless voice input unit, a song requesting unit, a power amplifier unit, a full-color large screen, a music input module, a multi-frequency audio signal collection controller, an AI main controller, a man-machine input interface, a digital control channel, an analogue control channel, a light audio control channel, a remote analogue-digital integrated processing function module, a remote digital-analogue control distribution board, a live voice-operated light drive array, a pump, a converter, a motor and digital quantity equipment, wherein the multi-frequency audio signal collection controller collects multiple segments of spectrum signals and transmits thespectrum signals to the AI main controller; and the AI main controller carries out spectrum analysis, communication control, analogue-digital output and light music control, processes and analyzes the spectrum signals and then separates out a digital control signal, an analogue control signal and a light color change control signal. According to the AI control interaction system, interaction of aman and the fountain can be achieved, and specific water form and light can be automatically turned on and manual editing is not needed.
