Stemmetje is a singing vocal robotic instrument created by composer Troy Rogers. The instrument is capable of producing various voice-like utterances. Stemmetje consists of two automatically tuned Helmholtz resonators covering the range of the lowest human vocal formants, with a linear actuator positioning the aperture of each resonator and modulating its center frequency. The instrument is a hybrid, mixed signal system that operates as a robotic formant synthesis organ. Stemmetje excels at overtone singing, sublingual robot poetry, yodeling, data sonification, improvisation, rhythmic machine vocalese, and more.
