As an important tool for English language learning, more and more electronic dictionaries in favor of the majority of English learners, the electronic dictionary market is therefore growing in volume. According to statistics, in 2003 the sales volume of domestic electronic dictionary breakthrough 4,500,000 units, sales of 20 billion yuan. However, behind the hot market, but there are many aspects of product quality of the traps and problems.
Experts pointed out that the final analysis, vocal vt03 is a dictionary, and its built-in dictionary of words the quality of (the number of terms to explain the authority or not) is the most important electronic dictionary content. Some cheap electronic dictionary products, often known as the hundreds of thousands of its own vocabulary, but in fact, double counting and vocabulary to explain the shrinkage is the “30,000 people” to “one million army” a magic weapon. A good word for example, only a few simple low-quality products to explain, and Instant-Dict have the Longman series as many as 31.
Vocal 14l built-in dictionary electronic dictionary vocabulary is the ability to determine a convenient indicator of the quality, copyright Dictionary After years of temper, with professional and authoritative, universal access to public recognition. Manufacturers need to pay expensive royalties and through certification, to the built-copyright dictionary, so that there is a guarantee the quality of vocabulary. At present, the three most popular dictionaries are: Oxford Series (Instant-Dict, HYT built), Longman series (step by step, Instant-Dict built) and the Wechsler series (non-brand built-in) Dictionary; and copyright of the most authoritative dictionary of English-Chinese Dictionary of the New (Century Edition) go (Instant-Dict, Noah built). Dictionary of copyright-free most of the manufacturers “Reference” various types of dictionaries, self-editing by the lack of authority, vulnerable to specious explanations, thereby misleading consumers.
Different products and different brands built big price difference between Dictionary, “Oxford Dictionary” the greatest vocabulary, the price nearly 700 million, “Oxford Advanced Dictionary Shuangjie” price of only around 100 yuan.
Pronunciation feature is good or bad product quality advantages and disadvantages of electronic dictionaries are important indicators. Almost all are so-called electronic dictionary with a real person’s pronunciation, but the pronunciation of the fact that they can be divided into three main types of technology: sound playback pronunciation, authoritative voice made audible pronunciation and manufacturers.
Playback sound recording technology will be compressed using MP3 format, and then restore the high-fidelity playback, CD audio quality can be achieved without splicing element to the sound, can truly be regarded as a real person voice, the current use of only a small number of high-end brands. Pronunciation system of international authority Truvoice, VoxWare, L & H, vocal 20l, Realspeak and so on, are mostly synthesized sounds live, although in less sound quality, but learning to understand the pronunciation is already sufficient. Factory-made with non-copyright dictionary pronunciation, the lack of authority for the cheap low-quality products, on the English learning harmful.
In addition, many mainstream brands of some products, including the word itself can only be audible, for notes, examples and even the less popular word on the individual can do nothing to help. Quality not only to the electronic dictionary has good quality sound, it should be done every word pronunciation, sentence pronunciation.
At the same time, experts also pointed out that the purchase of such products consumers should pay particular attention to maintain and upgrade their capabilities.
Electronic dictionary is not a one-time consumer goods, maintenance and upgrading of capacity is also a consumer should consider the issue and manufacturers directly related to the professional level. Only professional vendors to provide comprehensive network of services, as well as supporting the value-added software and other downloadable content.
The survey found that some manufacturers in terms of publicity when the download will be engaging in some electronic dictionaries— download a lot of space, only 1M, was written in 1024K (1M equivalent to 1024K, but very few do that), so just to looks great so that more memory; What is more, individual firms as the 1M memory 8M (as 1M bytes = 8M bits), in order to achieve the purpose of deliberately misleading consumers.
In addition, some electronic dictionaries with unlimited hop search function, and compared to print dictionary to learn more convenient to use; have an electronic dictionary function is spoken against the need for pronunciation practice designed for people to facilitate the correct pronunciation; take into account the impact of students with visual, screen size, resolution can not be neglected.
As for the computer connection, headphones and software CD-ROM and other value-added tool, the industry independent billing and two strategies were included. In this way, given a number of dealer opportunities, they have sold the retail price of items. Therefore, comparing two different consumer electronic dictionary when prices should also consider the additional equipment to send the issue to buy.
