Dedicated hardware/software voice-to-text system

A text preparation system, comprising:

• a first and a second CPU, a random access memory (RAM), an audio coder-decoder (CODEC) module, a Universal Serial Bus (USB) module, a persistent memory and a display module interconnected by a bus system;
• one or more USB interfaces, a video output interface, a microphone input, a power input connection, and a pointer input device, all implemented on outside surfaces of a physical framework, and all communicating with elements connected to the bus system;
• a video display coupled to the display module connected to the bus system;
• a first voice-to-text software executed exclusively by the first CPU, which is dedicated to only the first voice-to-text software, selecting from a first lexicon comprising words and phrases in response to voice input by a user and entering the words and phrases in a document as machine-readable text;
• and
• a second voice-to-text software executed by the second CPU and operating as a correction application, selecting characters comprising letters and punctuation marks from a second lexicon;
• wherein voice commands enable the user to initiate the first and the second voice-to-text software and associated lexicons alternately, the second software and lexicon providing a corrections mode for errors made by the first voice-to-text software.
