The programs can be used to create text documents, such as letters or memos and can also be used with e-mail, databases and many other applications. Some voice recognition systems are very sophisticated and offer many options, others are less expensive with less power but may do the trick. To choose a voice recognition system that will help you or your child with your specific needs you will need to understand the different classifications of the various systems. Systems with adaptive voice files get better with use. The user corrects the software until it learns those sounds.
Most systems now are adaptive.
Speaker Dependent vs. Speaker Independent - A dependent system must learn each user's voice in order to operate effectively. Recognition improves after many hours of use as the software learns your voice. An independent system is one that works for everyone with no individual training necessary. Discrete vs. Continuous - Discrete speech means the speaker needs to have a small pause between words. Currently there is a rush for the method of continuous speech voice recognition.
