The various embodiments of the present invention provide a portable device for self-curing and treatment of speech disorders, wherein the device comprises a voice input means such as a microphone, a manual input means that allows the user to input or select the mode of operation through the keypad, a power inlet source. A microcontroller is implanted inside the device and configured to receive the user’s voice input through the microphone, alter the received input voice based on the user selected operation modes and various pre-programmed and built-in algorithms and produce an altered audio signal. An audio output means such as a speaker connector port is configured to send the altered audio signal from the microcontroller to the user through a speaker connector means. The device also comprises a visual display means such as an LCD which is configured to display various parameters such as of speech, loudness w.r.t. noise level, rate of speech, correlation with delay etc.
