Voice recognition system
TLDR
In this article, the authors proposed a text locating system that allows a user to switch between a dictation mode, which inserts recognized words into text, and a search mode which uses them to search for new cursor locations.Abstract:
A text locating system recognizes spoken utterances, uses the recognized words as a search string, and searches text for words matching that search string. The probability that a given vocabulary word is selected as a search word is altered both by limiting the recognizable vocabulary to words in the text to the searched, and by altering the probability that individual recognizable words will be selected as a function of the number of time they occur in that text. The system performs incremental searches by adding successively recognized words to the search string and searching for the next occurrence of the string in response to each such addition. The invention can be used in a text editing system which enables a user to switch between a dictation mode, which inserts recognized words into text, and a search mode, which uses them to search for new cursor locations. Broadly speaking, the invention provides a computer system which recognizes spoken words, which has a data structure representing words; which uses that data structure for a purpose other than speech recognition; and which alters the probability that a given vocabulary word will be recognized as a function of the frequency of that word in the data structure.read more

Using context information to facilitate processing of commands in a virtual assistant
TL;DR: In this article, a virtual assistant uses context information to supplement natural language or gestural input from a user, which helps to clarify the user's intent and reduce the number of candidate interpretations of user's input, and reduces the need for the user to provide excessive clarification input.

Speech recognition system with delayed output
Hiroaki Sakoe,Seibi Chiba +1 more
TL;DR: In a speech recognition system of the type including a recognition unit responsive to a voice input and a conditioning input for recognizing the voice input to produce a recognition output, a start signal is produced whenever a voiceinput exceeds a threshold level and a pause interval detection signal isproduced.

Noise compensation arrangement
TL;DR: Adaptive speech recognition is improved by extracting an estimate of the background noise during unknown speech input, and using the noise estimate to modify the noiseless prestored reference speech signals for comparison with the input.

Speaker identification system using word recognition templates
TL;DR: In this paper, a set of signals representative of the correspondence of the identified speaker's features with the feature templates of said reference words is generated, and an unknown speaker is analyzed and the reference word sequence of the utterance is identified.
