In one exemplary embodiment of the invention, a method is provided for arranging voice feedback to a digital wireless terminal device, which includes a voice-assisted user interface (Voice UI), wherein the terminal device gives a voice feedback corresponding to its state. The terminal device includes memory devices (PPM) for storing the voice feedbacks. In the method, the following stages take place to arrange the voice feedback in connection with the terminal device: one or more voice feedbacks are generated, the generated voice feedbacks are converted into a digital form, the digitalized voice feedbacks are edited with chosen algorithms (ACELP) in order to reduce their file size, and the edited voice feedbacks are stored in a memory (PPM) arranged in connection with the terminal device.
