ABSTRACT

A talking voltmeter is a device that measures the value of voltage and also, as an additional feature, speaks out the value of voltage measured. A device capable of this operation and a “talking” facility is not available at a cheap cost in the market today. This device is capable of measuring a voltage upto 5V with a precision of 0.1V.

The analog input is fed into an ADC. This analog voltage is thus converted to the equivalent digital value. This is then followed by interfacing to a record and playback IC. This IC speaks out the corresponding voltage value along with the unit through the speakers.
