Voice & speech AI
On-device keyword spotting and acoustic modeling that detect commands with zero latency and no internet — tuned to stay reliable in noisy, real-world environments, even over the sound of a live instrument.
Digital & AI Solutions
Digital apps & AI products for daily focus & productivity.
We are a product studio: everything below is technology we design, build, and ship inside our own applications. Our architecture favors contextual, low-latency, on-device intelligence and zero-friction voice control, so software responds to people instead of interrupting them.
Core capabilities
Audio processing
Real-time capture, waveform analysis, trimming, and playback engineering for studio-quality practice and creation tools on ordinary phones and tablets.
Generative & multimodal AI
Generative AI, computer vision, and multimodal models woven into products where they remove steps — bridging human behavior and software interaction instead of adding chat windows to everything.
Cross-platform product engineering
One product vision, natively shipped on iOS and Android — interface, media pipeline, purchases, and updates engineered end to end by the studio.
Featured product: VoiceCue Recorder
Our flagship application — and the purest expression of how we build.
Hands-free recording for musicians
VoiceCue Recorder is engineered for musicians and instrument learners who cannot compromise their posture or take their hands off their instruments to work a touchscreen. It sits on the music stand and responds instantly to the voice:
- Say “BEGIN” — recording starts
- Say “DISCARD” — the take is dropped and a fresh one starts
- Say “STOP” — the take is saved automatically
Why it matters
Keyword detection runs entirely on-device using a purpose-built acoustic model. Optimized audio thresholds filter out background interference and the instrument itself, keeping trigger recognition isolated and reliable through intense practice blocks — with zero cloud dependency and zero accounts.
Around the recorder sits a complete practice toolkit: advanced metronome, chromatic tuner, hands-free sheet music reader, vocal tools, and lesson folders with one-tap submission to teachers.
VoiceCue for schools & studios →What’s next
VoiceCue is the first product under the Zelion umbrella — not the last. We are developing further voice-first multimodal AI tools for creators and learners, each held to the same standard: private by design, instant to use, and yours to own.
