About INNVOX
INNVOX makes voice training tools for people who rely on their voice every day: singers, teachers, speakers, and creators.
Who We Are
INNVOX is a voice training brand of 旋梯科技（深圳）有限公司, a company based in Shenzhen, China and established on September 1, 2026. We design the INNVOX adjustable-resistance voice training whistle, sell it directly on innvox.ai, and build the INNVOX training app.
Our Story
Voice teachers often recommend semi-occluded vocal tract (SOVT) exercises, such as humming through a straw, to warm up before demanding voice work. In real life the straw gets forgotten, bent, or thrown away, and its resistance changes every time you switch to a new one.
We started INNVOX to turn that exercise into a small tool you can keep with you. One pocket-sized whistle with a red slider lets you find a resistance that feels right and come back to the same setting tomorrow, whether you are about to sing, teach, present, or go live.
What We Make
- INNVOX SOVT voice training whistle: adjustable resistance, BPA-free food-grade plastic, 8.9 × 3 cm, reusable.
- INNVOX training app: guides short voice routines and gives feedback on pitch, volume, and stability. The analysis runs on your phone.
What You Can Count On
- Short, repeatable routines: a few focused minutes before a class, a show, or a call.
- Honest claims: INNVOX is a vocal training product, not a medical device.
- Buying with confidence: secure PayPal checkout, free tracked shipping, and 30-day returns.
- Real people answering: we reply to every email within 2 business days.
