A design of speaker-independent medium-size phrase recognition systemLai, Zhao-Hua 12 September 2002 (has links)
There are a lot of difficulties that have to be overcome in the speaker-independent (S.I.) phrase recognition system . And the feasibility of accurate ,real-time and robust system pose of the greatest challenges in the system.
In this thesis ,the speaker-independent phase recognition system is based on Hidden Markov Model (HMM). HMM has been proved to be of great value in many applications, notably in speech recognition. HMM is a stochastic approach which characterizes many of the variability in speech signal. It applys the state-of-the-art approach to Automatic Speech Recognition .

A Design of Speech Recognition System for Chinese NamesChen, Yu-Te 11 August 2003 (has links)
A design of speech recognition system for Chinese names has been established in this thesis. By identifying surname first, that is an unique feature of the Chinese names, the classification accuracy and computational time of the system can be greatly improved.
This research is primarily based on hidden Markov model (HMM), a technique that is widely used in speech recognition. HMM is a doubly stochastic process describing the ways of pronumciation by recording the state transitions according to the time-varing properties of the speech signal. The results of the HMM are compared with those of the segmental probability model (SPM) to figure out better option in recognizing base-syllables. Under the conditions of equal segments, SPM not only suits Mandarin base-syllable structure, but also achieves the goal of simplifying system since it does not need to find the best transformation of the utterance.
A speaker-independent 3000 Chinese names recognition system has been implemented based on the Mandarin microphone database recorded in the laboratory environment.

To Translate and Adapt a text with Long Sentences : With Focus on ReadabilityNyqvist, Anna January 2012 (has links)
When translating from English into Swedish long sentences may be a problem. In this paper an academic text with long sentences and an abstract content is translated and adapted for a larger target reader group. The strategies used in this process of translation and adaptation to make the text more readable are analysed regarding changes in sentence structure, noun phrases and connectors. The terminology of Vinay and Darbelnet’s theoretical model for translation strategies is used to describe some of the changes found. Transposition, such as changes from nouns to verbs and modulation, such as changing from abstract to concrete are frequently used strategies in the process of making the translation adapted for new readers. Furthermore, long sentences have been broken into two or more shorter ones and in this process the importance of connectors has increased to keep the information together. To see the effects of the changes LIX and the ratio between number of nouns and verbs have been used. The LIX value decreased from 64 till 56 for the whole text and the noun verb ratio decreased in all the sentences analysed.

Verb-stranding VP ellipsis : a cross-linguistic studyGoldberg, Lotus Madelyn January 2005 (has links)
This thesis presents a study of a construction which I refer to as Verb-Stranding VP Ellipsis. The construction is studied here, specifically, in two distinct senses. First, in chapter two, diagnostics are proposed by which the VP Ellipsis ("VPE") construction can be identified—irrespective of whether the main verb involved is null or overt. It is proposed that these diagnostics can be used to rule out the possibility that the data at issue are cases of other types of null anaphora, such as null arguments, Stripping, Gapping, and Null Complement Anaphora. It emerges from this section of the thesis that Modern Hebrew, Modern Irish, and Swahili have V-Stranding VPE data which form a natural class with English's Aux-Stranding VPE, while Japanese, Korean, Italian, and Spanish do not. The second focus is the question of how V-Stranding VPE should be generated. Chapters 3 and 4 argue in favor of an analysis involving PF Deletion of a VP out of which the main verb has raised, and against an LF Copying treatment. These arguments, in part, involve the Verbal Identity Requirement on VP Ellipsis, a novel generalization involving strict identity in root and derivational morphology between the antecedent- and target clause main Vs of the construction. Within the previously known requirement that elided phrases express semantically Given information, I argue that this generalization results from the fact that the head of an elided phrase must itself express Given information—whether or not the head surfaces as phonologically null. / Dans cette étude, on considère en detail une construction que j'appelle « L'élision d'une expression verbale sans l'élision du verbe principal » (anglais « V-Stranding VP Ellipsis »). Cette construction est étudiée ici, spécifiquement, dans deux sens distincts. Dans le chapitre 2, on propose des diagnostics grace auxquels on peut identifier la construction « élision d'une expression verbale » (« EEV », anglais « VP Ellipsis »), que le verbe principal dans l'expression verbale soit manifeste ou élidé. On soutient que ces diagnostics peuvent être utilisés pour éliminer la possibilité que les données pertinentes soient des exemples d'autres types d'anaphore nulle, tels que argument du verbe nul, le « Stripping », le « Gapping », et le « Null Complement Anaphora ». Ainsi, on propose dans cette section que l'EEV sans l'élision du verbe dans les grammaires de l'hebreu, de l'irlaindais et du swahili forme une classe naturelle avec l'EEV avec l'élision du verbe en anglais. On soutient aussi que cette construction n'existent pas en japonais, en coréen, en espagnol, ou en italienne. Ensuite, on considère la question de comment génerer les exemples d'EEV sans l'élision du verbe. Dans les chapitres 3 et 4, on propose une analyse qui utilise la suppression d'une expression verbale au niveau de la Forme Phonologique (« la suppression FP », anglais « PF Deletion ») aprês le placement du verbe principal a une position en dehors de l'expression verbale, et on presente une explication de la raison pour laquelle une analyse qui utilise des copies de la Forme Logique (« copie FL », anglais « LF Copying ») n'est pas viable. Ceci implique, en partie, la Condition d'Identite Verbale, une généralisation proposé ici pour la premiêre fois, impliquant une identité stricte de la racine et dans la morphologie dérivationnelle entre les verbes principaux des propositions antécedentes et des propositions ciblés. Dans le cadre de la condition connue selon laquelle les syntagmes élidés expriment une information sémantique donnée (anglais « Given »), j e soutiens que la condition d'identité verbale resulte du fait que la tete d'un syntagme élidé doit elle-meme exprimer l'information donnée sémantiquement—que la téte soit phonologiquement manifeste ou nulle.

"You know, I know" : functions, uses, and acquisition of the Japanese noda predicateRenovich, Sachiko Omoto 11 1900 (has links)
In the Japanese language, there are various modal elements, which mark speakers'
subjective attitudes toward propositions. One of the most common modals is the noda
predicate, which possesses the dual function of either asserting the truth of the position or
relaying the speaker's desire for information sharing. Japanese Native Speakers (JNSs) use
noda frequently in conversation; however, Japanese Language Learners (JLLs) often face
difficulty in learning noda because of its wide variety in function and use. To determine the
nature of noda use, this study examines conversational data from role-plays and a case study
of two JLLs. The main aims of this thesis are 1) to review research on noda and to provide a
cohesive and concise explanation of its functions and 2) to examine the use and acquisition
of noda by JLLs.
Following Noda's (1997) categorization, noda can be divided broadly into two types:
scope and mood. Noda of scope exhibits the speaker's assertion that the proposition is true,
while noda of mood marks the speaker's strong desire for information to be shared by
speaker and hearer. This study proposes a framework with which to understand the functions
of noda, and classifies information which is speaker-oriented (+ Speaker/- Hearer knowledge),
hearer-oriented (-Speaker/+ Hearer), and shared (+ Speaker/+ Hearer). JLLs first tend to use
noda with speaker-oriented information, and later acquire functions related to hearer-oriented
and shared information.
In the study of role-plays, JLLs with higher oral proficiency levels as rated by the
ACTFL-OPI (Oral Proficiency Interview) used a higher frequency of noda. Both the JLLs
and JNSs used noda primarily to provide and seek explanations. The intermediate-level JLLs
underused noda in providing supplemental explanations. Other uses of noda in the role-plays
included emphasizing information, seeking validity, and back-channeling. The two JLLs in
the case study did not notice the use of noda during conversations with the JNS, but began to
use noda more frequently during practice conversations upon receiving explicit instructions
on the use of noda. While the post-test did not demonstrate increased use of noda due to the
limited time of this study, there are clear indications for pedagogy. First, because the
functions of noda are varied and numerous, Japanese language textbooks and classrooms
should not be limited in providing only the 'explanation' function of noda. Second, the
frequent use of noda in Japanese conversation suggests that it should be an area of focus in
oral practice. Finally, JLLs need to develop skills in both comprehension and production of
noda to improve their Japanese discourse.

A theory of lexical functors : light heads in the lexicon and the syntaxSuzuki, Takeru 11 1900 (has links)
This thesis advances a specific model of 1-syntax, based on Hale
and Keyser (1993, 1994) and Dechaine (1996) as a point of departure,
and also proposes a general theory of the relation between the lexicon
and the syntax. One of the essential proposals that I make is the
F\mctionalization Principle, which permits a lexical head to project a
functional projection if and only if the meaning of the head is
represented by 1-syntactic structure without any extra semantic features.
I refer to this type of head as a light head. The Functionalization
Principle leads us to a principled account of various lexical and
functional uses of lexical items such as a passive morpheme -en and
have.
Examples that support my analysis range from adjectival and
verbal passives (e.g. Mary is very pleased and The glass was broken by
BUI), to constructions of alienable and inalienable possession (e.g. John
has Jive bucks and John has blue eyes), to causative/experiential
constructions (e.g. John had his students walk out of class), and to perfect
constructions (e.g. Lucie has advised the prime minister). Furthermore,
the analysis of possessive have is extended to possessive nominals (e.g.
John's cat and John's eyes).
I also examine the implications of the theories of 1-syntax and 1-
functors for Case. I propose that 1-syntactic structure partly determines
inherent Case whereas the 1-functor checks what I call l-Junctor Case
through the Spec-head relation. Furthermore, I show that these analyses of inherent Case and 1-functors account for essential properties of
possessive D (a genitive marker -*s), some Hindi marked subject
constructions and Japanese experiential transitive constructions.

Object noun phrase dislocation in Mandarin ChineseQu, Yanfeng 05 1900 (has links)
This dissertation studies leftward dislocation of object Noun Phrases in Mandarin Chinese
within the framework of Government and Binding theory. Although the canonical word order
in Chinese is S(ubject)-V(erb)-O(bject), it also exhibits OSV and SOV word orders. After an
introduction in Ch. 1, I discuss OSV constructions in Ch.2. I argue that the S-initial object NP
is moved there, since its association with a gap in the canonical object position obeys the
subjacency condition. Based on several diagnostic tests, I propose that Chinese has two kinds
of short-distance NP fronting: one is A’-movement and the other is A-movement. Adopting the
Split Infl Hypothesis, I postulate a fully articulated clause structure for Chinese. In particular,
I propose that the fronted NP in A-movement lands in [Spec AgrOP] as a kind of overt raising,
while the one in A’-movement further leaves that spec position and is CP-adjoined. I also
examine long-distance NP fronting, showing that it is invariably A’-movement.
In Ch. 3, I investigate object shift, which yields SOV constructions. I argue that this
syntactic process represents a type of A-movement, not A’-movement as concluded in previous
studies. Specifically, I propose that the subject NP and the object NP in this construction overtly
raise to [Spec AgrSP] and [Spec AgrOP] respectively.
In Ch.4, I examine the interactions between an object wh-NP and dou, the adverb of
universal quantification. I propose that wh-phrases, like indefinites, can be either
presuppositional or existential. If they are within VP (i.e. remain postverbal), they are subject
to existential closure and get an existential/interrogative reading. If, however, they are outside
VP (i.e. shifted to the left of dou), they define the range of the quantifier dou and obtain the
presuppositional/universal reading. The conclusion is that there is a strict correlation between
the S-structure positions of the wh-phrase and its interpretations. The exhaustive list reading of
the in-situ wh-object associated with the interrogative reading is derived from the fact that it is
in the scope of dou at S-structure.
In Ch. 5, I summarize the major findings of this dissertation and raise several issues for
future research.

Linking arguments to phrase structure : a study of passives, psych verbs, and ditransitive verbs in JapaneseMatsuoka, Mikinari. January 2001 (has links)
This thesis investigates the question of how the arguments of a given verb are linked to positions in a phrase structure. Through a study of passives, psych verbs, and ditransitive verbs in Japanese, it provides empirical support for the hypothesis that arguments having particular thematic roles are associated with particular syntactic positions systematically. / Chapter 2 deals with passives, in particular, two types of passive constructions, direct and indirect passives. Following some previous works, it is argued that the subject of a direct passive is generated in the same position as an object of the corresponding active verb, having the same thematic role, whereas the subject of an indirect passive is projected as an argument of a separate predicate. Several pieces of evidence for this hypothesis which are not given in the literature are provided here. / Chapter 3 is concerned with psych verbs, focusing on those that participate in a causative alternation. It is proposed that causative counterparts of these verbs can have two different structures that are parallel to the two types of passives discussed in Chapter 2. The subject of one type is generated in the same position as the object of the noncausative counterpart, having the same thematic role, whereas the subject of the other type is projected as an argument of a separate predicate. / Chapter 4 takes up ditransitive verbs, specifically, those that have inchoative counterparts, which do not project the subject of the ditransitive construction. There are two types of such verbs: one promotes the accusative argument of the ditransitive construction, rather than the dative one, to the subject of the inchoative counterpart, while the other chooses the dative argument over the accusative one for the subject of the inchoative counterpart. It is argued that this reflects the difference in the base-generated position of the dative argument between the two types of verbs. Moreover, the dative arguments of the two are distinguished in terms of thematic role. / This research is meant to contribute toward having a further understanding of how the participants of an event are expressed in grammatical forms.
