Abstract

The utility model discloses an automatic answering conversation learning machine. The machine comprises a microprocessor, a flash memory, a conversation selection key circuit, a display circuit and a voice digital-to-analog conversion circuit which are connected with the microprocessor, a power amplifying circuit which is connected with the digital-to-analog conversion circuit, a speaker which is connected with the power amplifying circuit, and a liquid crystal display (LCD) circuit, wherein an automatic answering conversation practice program is built in the memory. During use, the automatic answering conversation learning machine is turned on to ensure that the program which is built in the memory runs and a learner can select a conversation topic on an LCD screen through a key and begins a conversation with the machine. Every time the machine 'says' a sentence through a voice processing and amplifying system, the learner can select different sentences to answer through the key; the machine processes a selection signal of the learner and then finds out the corresponding sentence to answer; and the process is repeated in the way. The automatic answering conversation learning machine is favorable for practicing to use a conversational language and training language sense.

Description

Auto answer session learning machine

Technical field

The utility model relates to a kind of language conversation learning device, particularly relates to a kind of auto answer session learning machine.

Background technology

Exercise statement pronunciation, existing language conversation learning tool comprises language repeater and electronic dictionary.Language repeater can recording, playback, pronunciation relatively wait.Electronic dictionary contains the session recording, supplies the learner to listen and note, and it also can add above-mentioned language repeater function wherein.All there is a fatal weakness in above-mentioned learning tool, is exactly the means that a kind of auto answer session is not provided, and makes the learner really to participate in session wherein; Only be to hear the note note, and key is to be not only the exercise pronunciation, and; To understand from the content implication, grasp and use vocabulary and sentence, in the actual life; Because the urgency levels of litigant's identity, environment of living in difference, thing are not equal, and same problem is had different reactions.And the language learner is exactly the thought and sentiment that will learn under different situations, to express oneself.Existing language learner can't reach these requirements.

Summary of the invention

To above-mentioned deficiency; The utility model provides a kind of auto answer session learning machine; Make the learner can participate in session, in each dialogue, can select to use statement, and machine is according to learner's different choice; Different replying arranged again, thereby whole session constitutes a complete learning process.

For achieving the above object, the utility model adopts following technical scheme:

The utility model auto answer session learning machine comprises: a microprocessor, and what be connected with microprocessor has storer, a session selection key circuit; Display circuit, the sound D/A converting circuit, what be connected with said D/A converting circuit has a power amplification circuit; What be connected with said power amplification circuit has a loudspeaker; Said memory built-in has auto answer session exerciser, makes the learner can select the session topic, and; In each session of session paragraph, the learner can carry out session by case statement.

In the utility model auto answer session learning machine, said session selection key circuit comprises the session selector button, is connected with control circuit with said session selector button, and said control circuit links to each other with said microprocessor.

In the utility model auto answer session learning machine, also comprise the LCD display circuit.

Owing to adopt technique scheme, the utlity model has following technique effect: during use, open the utility model auto answer session learning machine, the program run of said FLASH memory built-in.The learner can select session topic and machine to begin session on LCD display through button.When machine " was said " in short through acoustic processing and amplification system, the learner can select different replying through button; And machine is handled for learner's selection signal, finds out corresponding statement again and replys, so back and forth.Like this; The learner can personally understand the content implication of each each sentence of vocabulary; Understand the linking of hereinafter in the session, and the variation of understanding content and emotion in the session, so the learner can physical experience be in " with people's dialogue " to oneself; This practises using conversational language and cultivates feel for the language for the learner, and very big benefit is arranged.
