Speech Bubbles large illuminated speech-bubble structures in public park at night. Development render.
Speak into a microphone. Your words inflate a balloon. They shimmer with colour. The sounds of your speech replay in the room, woven into a musical score โ a celebration of voice, diversity, and the languages that connect us.
The Concept
Speech Bubbles was commissioned for the MKIAC (Milton Keynes International Arts Collective) yearly festival "Art in the Park." The installation responds to a central idea: that voice is the most intimate and universal material we have, and that every voice โ in any language, with any accent โ deserves to be held, amplified, and celebrated.
Audience members are invited to share their voice into a microphone. Their spoken or sung words trigger the inflation of balloons, which shimmer and shift colour in response to the sound. The room fills with the accumulated sounds of everyone who has spoken, layered and woven into a musical composition that evolves with each new voice.
The Commission
The piece was created to celebrate the rich tapestry of diversity and language present at the festival. Though the festival was ultimately cancelled before the installation could premiere publicly, the work was completed and stands as a fully realised piece ready for future exhibition.
The installation is designed to scale โ from intimate gallery settings to outdoor festival environments โ with the balloon density and audio complexity adapting to the space and the number of participants.
Technical System
The system captures voice input, analyses its characteristics, and triggers corresponding physical and audio responses in real time.
Audio Processing Chain
- Directional microphone array for clean voice capture in noisy environments
- Real-time audio analysis: volume, pitch, and spectral character
- Variable delay and layering โ voices accumulate and are replayed in the space
- Musical score that responds and adapts to the character of incoming voices
Balloon Inflation System
- Custom pneumatic system controlled by audio analysis data
- RGB LED arrays inside balloon chambers for colour response
- Inflation rate modulated by voice volume and duration
- Colour shifts mapped to pitch and tonal quality
- Automatic deflation cycle to reset for new participants
Voice as Material
Catherine's musical score was designed as a scaffold โ a harmonic and rhythmic environment that catches voices and makes them beautiful regardless of their character. A whisper becomes intimate; a shout becomes celebratory; a song becomes something that fills the room. The piece doesn't judge voices, it elevates them.
The accumulated voices at the end of an exhibition session create a kind of polyphonic portrait of everyone who has participated โ an audio archive of the event's community.
