A guiding device for lection reading and the relevant method is provided, which comprises a display, a microprocessor, a clock oscillator, storage, a phonetic integrated circuit, a microphone, a loudhailer, an audio output port, a control button and a volume control button. The display itself is equipped with a display driver while the phonetic integrated circuit is composed of an audio input interface, an audio output interface, a multi-section phonetic storage and an audio signal amplifier. The method of the lection reading under guidance is that: firstly, after digital compression, respectively pre-storing four groups of the lection and the audio prompts of beginning, intermediate and advanced levels, which are combined with date conditions of each week by software programming, into the multi-section phonetic storage inside the phonetic integrated circuit. Twelve different levels of the phonetic prompts are combined with the lection content to guide the user to read the lections. With the lection-reading guiding device by direct audio prompt which is simply controlled and conveniently operated, the said device and method simplify the lection reading and learning for different users.
