Description

Electronic pronunciation book device

technical field

The utility model relates to a pronunciation device, in particular to an electronic pronunciation book device capable of emitting pronunciation according to the position indicated by a learner on a work surface, and belongs to the field of electronic technology.

Background technique

One of the most important aspects of language learning, especially foreign language learning, is pronunciation and listening training. In order to firmly grasp the pronunciation of the language to be learned, people must rely on a large number of repeated listening and reading exercises to achieve the corresponding learning goals.

For the convenience of learners' listening and reading exercises, many manufacturers have developed and produced electronic dictionaries that can produce sounds. In the electronic dictionary, a large number of words and sentences and their pronunciation data are stored. When students or workers need to look up words and sentences through the electronic dictionary, they can input the words through buttons or other input methods, and the electronic dictionary can output the definition and pronunciation of the words through the display screen and sound-generating parts through retrieval. . This kind of electronic dictionary basically follows the traditional dictionary look-up mode, only changes the retrieval method to electronic intelligence, and increases the pronunciation at the same time, but it still does not break away from the rigidity and rigidity of the traditional dictionary on the whole, and it lacks humanization. It is a tool for studying and working, and it is not suitable for young people's learning and use.

In addition, some manufacturers have researched and produced repeaters. The repeater is composed of a tape playback device, a sound recording device, and a microphone. During use, the learner utilizes the tape playback device to broadcast the reading or read aloud by himself, and the above-mentioned sound is transmitted to the sound recording device through the microphone and/or the internal audio circuit to achieve the purpose of recording, and the control record is installed on the repeater Buttons and circuits for the length of the sound, so that users can control the recording conveniently.

The biggest difference between a repeater and an electronic dictionary is that the tape it plays matches the corresponding textbook or other learning materials. Users can change the tape in the repeater according to different teaching materials and corresponding learning content. The disadvantage of the repeater is that the tape installed inside it records the pronunciation data sequentially. When the user is studying, he often needs to repeatedly operate the repeater to find the pronunciation of words that match the content of the textbook. Additional functions that can help the user operate, but still cannot completely free the user from operating the device. Especially when the user is a younger child, there must be an instructor to help it operate the repeater.

To sum up, only by connecting the teaching content with the sound-producing equipment in a simple and rigorous way can learners be freed from complicated machine operations, eliminate the dull and rigid learning atmosphere, and enable them to focus more on learning. middle.
