Description

The combined intelligent language playback device

Technical field

The utility model relates to a kind of language repeater, relates in particular to a kind of novel combined type intelligent language language repeater.

Background technology

Learn a language, foreign language especially, at present the effective ways of promoting be with the sentence be unit listen to repeatedly, with reading imitation and writing from memory.Normally cartridge player and the semiconductor voice storage of 10 seconds-hundreds of seconds durations of existing various language playback device, the combination of playback circuitry.During use, with the model speech reproduction in the tape a bit of in the storage of its semiconductor voice, the playback circuitry for the repeat playing multipass, and must not play every all over the tape that all unrolls, thereby increase than the efficient that learns a language with common tape player.

But existing various language playback devices still have common shortcoming:

1. volume is big, and power consumption is many, and most of users all rely on electric main work, thereby can not be portable, and inconvenience will be used for study scamble time.

But though the voice repeat playing multipass of 2. its semiconductor voice storage of typing, playback circuitry, and must not play the tape that all unrolls for every time, must start tape duplication once more if will listen to next section; If will listen to the last period, the tape search that must unroll duplicates behind the location again.And used storer is volatile memory (RAM), after the power failure wherein voice promptly lose, start next time is if want to review same content, the tape search that also will unroll duplicates behind the location again, so efficient is still not high enough, cause boredom easily, and acoustic tape and wear and tear in machines are very fast.

3. facts have proved, be that unit carefully listens to repeatedly, imitates with the sentence be to improve to listen, say the ability most effectual way, and general tin of extensive reading poor effect of big section, during so existing language repeater uses, generally once only duplicate one, two words, semiconductor speech memory greater than one, two word durations can not be fully utilized, and increases cost on foot.Partition sentence automatically is deposited unless this storage, playback circuitry possess, freedom is searched for positioning function by the sentence forward/backward.

Summary of the invention
