The program will analyse your system and come up with a recommended Speech Model and Vocabulary, but it is possible to over-ride this to a certain extent. The other option refers to the Mobile option, where you create a speech file for transcribing material recorded onto a tape recorder. This option will not be dealt with in this Guide. The next window provides instructions on how to position the microphone for the best results. The recommended position is to the side of the mouth, about a thumb width away from the mouth.
Microphone position is crucial to good recognition accuracy.
If the mic is placed in front of the mouth, it will pick up breaths, and try to interpret them as words. That you didn't actually include in your dictation. If it's too far away from the mouth, the signal to noise ratio will be too low, again affecting recognition accuracy. This is where the program adjusts the volume settings on the sound card to suit each voice. When you click the button, the text goes black, and you simply read the text until the program beeps to tell you it is finished adjusting the volume settings.
