Yumi Kubo

Chief Executive Officer / Founder

Yumi is the mother of two children. Her son, Wataru, was diagnosed with autism at the age of one. She carried around a binder full of icons when he was young, which eventually grew to 20 pounds. She also bought a conventional communication device with medical insurance, but it was not good fit for her son (and he would never use it). When the iPhone emerged on the market, she decided to purchase an app. Nobody around her was make it work including his speech therapist, and Spectrum Visions' co-founder/CTO (, who has Ph.D. in Rocket Science from Stanford). This motivated her to create the Voice4u application in the summer of 2009. Her vision is to create a communication app that is used by autistic individuals themselves as well as people helping them. Voice4u has also proved valuable for people who have suffered strokes or have other types of speech disabilities. Anyone can use it, and it is possible to add up to a 1,000 new cards. She believes that economic and emotional burdens for families with autistic or physically disabled members should be lessened. She loves running 5-K races, and kids' smiles.
