Effect of reference set selection on speaker dependent speech recognition by Zongge Li( Book )

6 editions published in 1981 in English and held by 10 WorldCat member libraries worldwide

This paper describes an algorithm for compressing the spectral representation of an utterance along the time axis while keeping the main features intact. The goal of the algorithm is to save template storage space and to reduce the time required for recognition. For 8 speakers, 5 data sets each, the results indicated that we can save about 40% of the template space and 35% of the recognition time with only a slightly higher error rate. (Author)

What a software engineer needs to know : I. program vocabulary by Mary Shaw( Book )

5 editions published in 1989 in English and held by 9 WorldCat member libraries worldwide

Abstract: "Software development, like any complex task, requires a wide variety of knowledge and skills. We examine one particular kind of knowledge, the programming language vocabulary of the programmer, by gathering statistics on large bodies of code in three languages. This data shows that most of the identifiers in programs are either uses of built-in or standard library definitions or highly idiomatic uses of local variables. We interpret this result in light of general results on expertise and language acquisition. We conclude that tools to support the vocabulary component of software development are wanting, and this part of a engineer's education is at best haphazard, and we recommend ways to improve the situation."
Minimizing computational cost for dynamic programming algorithms by Alex Waibel( Book )

1 edition published in 1981 in English and held by 7 WorldCat member libraries worldwide

In this study we introduce and test several methods to reduce the computational cost in dynamic programming algorithms for isolated word recognition systems. Three methods will be discussed in detail: (1) Pruning by preset thresholds, (2) Search based on the Branch and Bound technique, (3) Branch and Bound based search with additional pruning. Compared to conventional algorithms, Method 3 could be seen to yield a speed up of approximately a factor of 5, at no loss of recognition accuracy. The branch and bound method with pruning is also ideally suited for research oriented systems, since pruning is independent of the parametrization used (eliminates the necessity for retuning thresholds). Additional features of this method, which are of importance to maintaining the flexibility and diagnosticity needed for such a system, will be discussed. (Author)
Principal component analysis with missing data and its application to object modeling by Heung-Yeung Shum( Book )

3 editions published in 1993 in English and held by 6 WorldCat member libraries worldwide

We show that object modeling from a sequence of range images is a problem of principal component analysis with missing data (PCAMD), which can be generalized as a WLS minimization problem. An efficient algorithm is devised to solve the problem of PCAMD. After we have segmented surface regions in each view and tracked over all the sequence, we construct a 3F x P normal measurement matrix of surface normals, and an F x P distance measurement matrix of normal distances to the origin for all visible P regions appeared over the whole sequence of F views, respectively. These two measurement matrices, which have many missing elements due to noise, occlusion and mismatching, enable us to formulate multiple view merging as a combination of two WLS problems
On the use of environmental, syntactic, and probabilistic constraints in vision and speech by D. Raj Reddy( Book )

2 editions published in 1969 in English and held by 6 WorldCat member libraries worldwide

In this paper the author considers both vision and speech in the hope that a unified treatment, illustrating the similarities, would lead to a better appreciation of the problems, and possibly programs which use the same superstructure. The author postulates a general perceptual system and illustrate how various existing systems either avoid or ignore some of the difficult problems that must be considered by a general perceptual system. The purpose of this paper is to point out some of the unsolved problems, and to suggest some heuristics that reflect environmental, syntactic, and probabilistic constraints useful in visual and speech perception by machine.

Harp, a low-cost 25 MIPS digital processor by S Kriz( Book )

4 editions published between 1976 and 1978 in English and Undetermined and held by 6 WorldCat member libraries worldwide

Harp is an ultra-high performance processor motivated by the low-level processing requirements of machine perception tasks. It is designed for extreme speed, low cost, easy producibility, simplicity of structure and programming, and complete diagnosability. This paper discusses the design philosophy, architecture, instruction set, and performance of Harp. (Author)

Automatic speech recognition : the development of the SPHINX system by Kai-Fu Lee( )

2 editions published in 1989 in English and held by 6 WorldCat member libraries worldwide

Speech Recognition has a long history of being one of the difficult problems in Artificial Intelligence and Computer Science. As one goes from problem solving tasks such as puzzles and chess to perceptual tasks such as speech and vision, the problem characteristics change dramatically: knowledge poor to knowledge rich; low data rates to high data rates; slow response time (minutes to hours) to instantaneous response time. These characteristics taken together increase the computational complexity of the problem by several orders of magnitude. Further, speech provides a challenging task domain which embodies many of the requirements of intelligent behavior: operate in real time; exploit vast amounts of knowledge, tolerate errorful, unexpected unknown input; use symbols and abstractions; communicate in natural language and learn from the environment. Voice input to computers offers a number of advantages. It provides a natural, fast, hands free, eyes free, location free input medium. However, there are many as yet unsolved problems that prevent routine use of speech as an input device by non-experts. These include cost, real time response, speaker independence, robustness to variations such as noise, microphone, speech rate and loudness, and the ability to handle non-grammatical speech. Satisfactory solutions to each of these problems can be expected within the next decade. Recognition of unrestricted spontaneous continuous speech appears unsolvable at present. However, by the addition of simple constraints, such as clarification dialog to resolve ambiguity, we believe it will be possible to develop systems capable of accepting very large vocabulary continuous speechdictation
Representation of three-dimensional objects by D. Raj Reddy( Book )

5 editions published in 1978 in English and held by 5 WorldCat member libraries worldwide

This paper describes a system for generation and representation of computer models of arbitrary three dimensional objects. Three representations are explored which have varying time and space tradeoffs. These representations, which are tailored for irregular 3-D objects, store every input point exactly by using a tree structuring of the object space. Their advantage over more common representations is that they make perspective and hidden-surface elimination less difficult. In addition, one of the representations simplifies the storage of dynamic objects and objects with redundant sub-parts. (Author)
Eyes and ears for computers by D. Raj Reddy( Book )

4 editions published in 1973 in English and held by 5 WorldCat member libraries worldwide

The paper presents a unified view of the research in machine perception of speech and vision in the hope that a clear appreciation of similarities and differences may lead to better information-processing models of perception. Various factors that affect the feasibility and performance of perception systems are discussed. To illustrate the current state of the art in machine perception, examples are chosen from the HEARSAY speech understanding system and the image processing portion of the SYNAPS neural modelling system. Some unsolved problems in a few key areas are presented. (Author)

Contextual analysis of phonemes of English by D. Raj Reddy( Book )

3 editions published in 1969 in English and held by 4 WorldCat member libraries worldwide

It is now well known that the acoustic characteristics of a phoneme depend on both the preceding and following phonemes. This paper provides some needed contextual and probabilistic data about trigram phonemic sequences of spoken English. Since there are approximately 40 to the 3rd power such sequences, one must discover and study only the more commonly occurring sequences. To this purpose, three types of tables are presented, viz., (a) Commonly occurring trigram sequences of the form /abc/ for every phoneme /b/. (b) Commonly occurring sequences /abc/ for every pair of phonemes /a/ and /c/. (c) Commonly occurring word boundary sequences of the form /-ab/ and /ab-/ where /-/ represents the silence phoneme. Entries of the above tables contain examples of usage and probabilities of occurrence for each such sequence. (Author)
