An electronic competitive challenge is disclosed. A prompt is presented to a group of participants. A computer system with a speech recognition module listens for multiple, simultaneous speech utterances from the group of participants. Each speech utterance is decoded, assigned a priority or timing, and associated with one of the participants. Based on the priority or timing, the content of the utterances, and a predefined rule set, one of the participants is identified as the competitive challenge winner. The prompt may be an electronic image, and the utterances may relate to a concept associated with or reflected in the image. The image may be drawn by a human and presented in a visual sequence that tracks its original creation, or it may be an image that is automatically degraded using image processing to disguise its content.
