Blind Helper Voice is one of the low-cost, open source BlindHelperToolkit devices designed to help blind people.
It is a voice synthesizer that can be connected to commonly used devices such as kitchen scales, bathroom scales, clinical thermometers, air quality meters and others in development.
The first was BlindHelperBraille, a low-cost Braille printer for school use made with 3D printing, followed by the easy-to-use audiobook reader, the electronic medicine dropper and the sound keychain ambient light detector, all based on Arduino.
