  In this paper we present the design and development of the Transhuman
Ansambl, a novel interactive singing-voice interface which senses its
environment and responds to vocal input with vocalisations using human voice.
Designed for live performance with a human performer and as a standalone sound
installation, the ansambl consists of sixteen bespoke virtual singers arranged
in a circle. When performing live, the virtual singers listen to the human
performer and respond to their singing by reading pitch, intonation and volume
cues. In a standalone sound installation mode, singers use ultrasonic distance
sensors to sense audience presence. Developed as part of the 1st author's
practice-based PhD and artistic practice as a live performer, this work employs
the singing-voice to explore voice interactions in HCI beyond language, and
innovative ways of live performing. How is technology supporting the effect of
intimacy produced through voice? Does the act of surrounding the audience with
responsive virtual singers challenge the traditional roles of
performer-listener? To answer these questions, we draw upon the 1st author's
experience with the system, and the interdisciplinary field of voice studies
that consider the voice as the sound medium independent of language, capable of
enacting a reciprocal connection between bodies.
