TD Phone

Text and call using just your eyes on a TD I-Series (TD I-13 and TD I-16) device. TD Phone is an app designed for those who cannot use their voice and have limited to no mobility in their hands, due to conditions such as ALS/MND, multiple sclerosis, muscular dystrophy and cerebral palsy. Text or call anyone, anywhere without the need for Wi-Fi, thanks to a Bluetooth connection between your TD I-Series and your Android or iPhone. Search or scroll through your imported contacts in a simple, familiar way. Never miss incoming calls or texts with an easy-to-select popup. Compose messages efficiently with word and phrase prediction. Speak out loud during a call through your TD I-Series using a synthetic voice. It’s also possible to use a custom, synthetic clone of your natural voice, with a choice from among leading voice banking providers. TD Phone is exclusively for TD I-Series (TD I-13 and TD I-16) devices.
