Abstract
An accurate speech recognition system capable of rapidly processing greater varieties of words and operable in many different devices, but without the computational power and memory requirements, high power consumption, complex operating system, high costs, and weight of traditional systems. The utilization of individual letter utterances to transmit words allows voice information transfer for both person-to-person and person-to-machine communication for mobile phones, PDAs, and other communication devices. This invention is an apparatus and method for a speech recognition system comprising a microphone, front-end signal processor for generating parametric representations of speech input signals, a pronunciation database, a letter similarity comparator for comparing the parametric representation of the input signals with the parametric representations of letter pronunciations, and generating a sequence of associations between the input speech and the letters in the pronunciation database, a vocabulary database, a word similarity comparator for comparing an aggregated plurality of the letters with the words in the vocabulary database and generating a sequence of associations between them, and a display for displaying the selected letters and words for confirmation.
