New Information Technologies

Several businesses need to convert recorded voice to text and have long been looking for ways to do it quickly and inexpensively. Transcribing medical dictation is a prhyme example.

Some years ago, when voice recognition software became commercially available, most people expected that the solution had finally arrived. Businesses looked forward to cutting down on transcription costs and everyone who hated typing looked forward to getting rid of their keyboard.

Unfortunately, the reality turned out to be rather different. Voice-to-text technology has been a big let down so far.

The fact is, voice recognition software is easily thrown off track by many different factors. If you don’t speak clearly and distinctly, it may not give you the right output. If you try using it in a noisy place, it will fail more generally than not. If you have an accent, it may not understand you. Even if you have a bad cold, you’ll find that the software may give incorrect results!

In other words, voice recognition software works reasonably well under ideal, laboratory conditions, but not in a typical home or business setting!

Healthcare professionals who attempted to use voice recognition technologies to eliminate transcription services found that they need to “train” the software to function well. That takes a long time and a lot of work. Most wound up continuing to outsource their medical transcription work.

Of course, there are many other types of situations where transcription is needed. Examples include recordings of seminars, teleconferences, interviews and classes that need to be converted to text.

In natural speech, people tend to use lots of “aahs” and “umms” as well as unnecessary phrases like “you know”. Current voice recognition technology is just not capable of filtering out such irrelevant sounds or words.

In addition, people also string together several sentences using “ands”. The software cannot break up such speech into meaningful sentences. Nor can it break up speech into meaningful paragraph units the way a transcriptionist can.

And if the recording is filled with background noise, or if more than one person is talking at the same time, the software will not function reliably and consistently.

Maybe sometime in the future someone will invent voice recognition technology that can handle all the above issues. Till then businesses will need to use transcription services, particularly for work like medical transcription, where accuracy is critical.

Information Technologies

Like other portable consumer electronic devices digital cameras use batteries as their power source. In this article we will describe different battery technologies and their cons and pros. Armed with this knowledge you will be able to take into consideration the battery used when purchasing your next camera.

A camera usually supports just one type of battery either a disposable battery or a rechargeable one. The exception is cameras that are powered by standard AA, AAA or similar batteries. In most of these cases disposable and rechargeable batteries can be used interchangeably.

There are two battery types:

* disposable batteries: can only be used once. They usually have a standard size and shape such as AA, AAA and so on. You can buy these batteries at most stores and once they are empty you simply dispose them (please help keep the environment safe and clean by disposing batteries only to special battery disposal containers).

* rechargeable batteries: can be used multiple times. Some rechargeable batteries have a standard size and shape such as AA, AAA and so on. Such standard size batteries can be used anywhere that a disposable battery can. More often than not however rechargeable batteries have a proprietary shape and are compatible with just a few specific cameras. Once a rechargeable battery is empty you can place it in a special charger that will recharge it. The time it takes to recharge a battery, the number of times it can be charged and the life time of the battery are dependant on the technology used to build the battery.

There are pros and cons to using disposable or rechargeable batteries. The main advantage to using a disposable battery is that you can always buy a few to have with you to replace the ones that are empty and you can always get one in a store close-by in case you are stuck with empty batteries. The disadvantages to using disposable batteries are the cost of buying new batteries every times your batteries are empty, the capacity (in most cases a disposable battery will not last when a good rechargeable battery). On the other hand rechargeable batteries require only one purchase. When the battery is empty you can simply place it in its charger and after an hour or so you will have a fully recharged battery. The disadvantage is that if you run out of batteries during a photo shooting session or somewhere away from home or a power supply you can not only buy another battery. The solution to that problem is to buy one extra battery and to always carry it with you fully charged.

If your camera uses standard size batteries such as AA or AAA you can have the advantages of both disposable and rechargeable batteries. You can always use disposable AA or AAA batteries with the camera but you can also get a rechargeable AA or AAA battery and use it when convenient.

Rechargeable batteries technologies:

Different technologies are used in building rechargeable batteries. Look at the battery itself to find out what technology was used in most cases it will be written on a small sticker on the battery or somewhere on its packaging. The following are the most common technologies and some of their pros and cons:

* nickel cadium: one of the oldest technologies. These batteries are inexpensive, they can be recharged fast and many times before they lose their capacity. On the downside they have a low capacity and have a “memory effect” – a “memory effect” means that the battery can not be recharged to its full capacity unless it is first fully discharged. This can be problem since in most cases you will want to make sure your battery regardless of its current state is fully charged before going on a photo shooting session. Some charges solve this problem by first discharging the battery and only then recharging it to its full capacity.

* nickel metal hybrid: this technology is an improvement of nickel cadium. These batteries capacity is much higher up to 50% more. Although it still has a “memory effect” it is less noticeable than in nickel cadium batteries. On the downside these batteries can be charged less times before losing their capacity and they also discharge faster when not in use.

* lithium ion: A new technology that solves many of the nickel technology problems. Lithium ion batteries have a higher capacity than even nickel metal. They have no “memory effect” at all (and thus regardless of their current state they can always be recharged to their fullest capacity). The downside is that they are more expensive than nickel batteries.

* lithium polymer: the latest technology. These batteries have all the advantages of lithium ion and more. They have an even higher capacity and can also be easily manufactured in any shape or form. This allows for much smaller and lighter high capacity batteries and for batteries shaped to better fit the camera design.

Summing this up when choosing a camera and considering what batteries it uses you should first make a choice between disposable and rechargeable batteries. If you choose to get a camera that uses rechargeable batteries you should try to choose a battery that uses the latest technologies like polymer or lithium unless you have some special considerations.

It Management Software

If you own a computer and are connected to the world wide web then you will almost definitely have heard of spyware software and will also be at risk. The purpose of this article is to inform readers as to the risks of spyware software and explain exactly what spyware is and what it does.
