Modelling the effects of speech rate variation for automatic speech recognition
In automatic speech recognition it is a widely observed phenomenon that variations in speech rate cause severe degradations of the speech recognition performance. This is due to the fact that standard stochastic based speech recognition systems specialise on average speech rate. Although many …

The effects of speech rate, message repetition, and information placement on synthesized speech intelligibility
Recent improvements in speech technology have made synthetic speech a viable I/O alternative. However, little research has focused on optimizing the various speech parameters which influence system performance. This study examined the effects of speech rate, message repetition, and the placement of …

The Effects of Different Auditory Feedback Conditions on Speech Rate and Self-Perceptions of Speech
… auditory feedback. Dependent variabes were rate and self-perceptions of speech. Research hypotheses were: 1) any manipulation of auditory feedback affects rate and self-perceptions of speech in non-stutterers, 2) amplified phase-lagged fundamental frequency feedback affects rate and …

Speech Rate, Pause, and Linguistic Variation: an Examination through the Sociolinguistic Archive and Analysis Project
<p>Recordings of speech play a central role in the diverse subdisciplines of linguistics. The reliance on speech recordings is especially profound in sociolinguistics, where scholars have developed a range of techniques for eliciting and analyzing natural talk. Despite the focus on naturalistic …

From prosodic structure to acoustic saliency: an fMRI investigation of speech rate, clarity, and emphasis
Acoustic variability in fluent speech can arise at many stages in speech production planning and execution. For example, at the phonological encoding stage, the grouping of phonemes into syllables determines which segments are coarticulated and, by consequence, segment-level acoustic variation. …

Effects of voice coding and speech rate on a synthetic speech display in a telephone information system
Despite the lack of formal guidelines, synthetic speech displays are used in a growing variety of applications. Telephone information systems permitting human-computer interaction from remote locations are an especially popular implementation of computer-generated speech. Currently, human factors …

The effects of lexical stress, intonational pitch accent, and speech rate on vowel quality in Catalan and Spanish
… duration is further investigated by manipulating speech rate. The results show that in both languages vowels produced at faster rate are shorter and less peripheral than those produced at normal rate. Interestingly, the effects of stress differ in these languages. For Catalan, unstressed vowels …

Acoustic and perceptual analyses of politeness in Japanese speech
… acoustic cues for politeness in Japanese speech, fO and temporal aspects of polite and casual utterances of two question sentences spoken by six male native speakers were acoustically analysed. The analysis showed that fO movement of the final part of utterances and speech rate of …

An Exploratory Study of Effects of Lecture's Acoustic Features on L1 Chinese Listeners' Listening Comprehension of Online L2 English Lectures
This study explored the effects of lecture speech rate and duration on L1 Chinese listeners' listening comprehension of online L2 English lectures on free-recall and cued-recall questions. There are many factors that may affect a Chinese listener's listening comprehension of online English …

The effect of bilingualism on vocal parameters related to vocal fatigue among Spanish-English bilingual speakers
… It is well-known that language fluency affects speech production; however, there is little information on how it affects voice production. The goal of the current study was to identify the task and acoustic measures that could be applied to future research investigating vocal production in …

The effects of five discrete variables on human performance in a telephone information system
… information system. The five variables were: speech rate (120 or 240 words per minute), length of input time-out (two or ten seconds), feedback (available or not available), wallet guide - a graphical representation of the information (available or not available), and the database structure …

Assessing human performance trade-offs of a telephone-based information system
… The four factors manipulated were: synthesized speech rate, time available for user input, subject age, and background music level. Subjects searched a fictitious department store database for 16 specific store items and transcribed 16 information messages which were spoken by a computer speech …

Spanish pragmatic markers' usage patterns in second language and heritage speakers
… 2) to examine how the variables of proficiency, speech rate, language use, and participation in immersion programs affect their use of pragmatic markers. Based on previous research, I hypothesized that heritage speakers would outperform L2 learners of Spanish, therefore, they would use pragmatic …

A Study of Temporal Variables in English and Korean: Cross-Linguistic, Development, and Native/nonnative Analyses
… included were primary temporal variables (speech rate, articulation rate, pause-time ratio, mean length of runs, and mean length of pauses), secondary temporal variables (repeats, false starts, parenthetical remarks, drawls, unfilled pauses, and filled pauses), and temporal cycles. …

Measuring fluency: Temporal variables and pausing patterns in L2 English speech
… variables and pausing patterns in L2 English speech to investigate fluency as a measurable component of oral proficiency. Fluency can be defined as ‘speed and smoothness of oral delivery’. We can measure the speed of oral delivery through calculating temporal variables such as speech rate and …

Development of Guidelines for In-Vehicle Information Presentation: Text vs. Speech
… There are numerous systems that can be incorporated into vehicles and various ways in which the information can and should be presented to the driver. The way the information is presented to the drivers is extremely important in terms of increasing safety and decreasing driver distraction. The …

Weakening of Intervocalic /P, T, K/ in Two Spanish Dialects: Toward the Quantification of Lenition Processes
… by which the imperfect relationship between speech style and speech rate may be better understood, the consideration of the abruptness and degree of changes in relative intensity values in a vowel---stop consonant---vowel sequence as a potential metric by which stop lenition may be …

Factors influencing the efficacy of delayed auditory feedback in treating dysarthria associated with Parkinson's disease
… disease patients exhibit a high prevalence of speech deficits including excessive speech rate, reduced intelligibility, and disfluencies. The present study examined the effects of delayed auditory feedback (DAF) as a rate control intervention for dysarthric speakers with Parkinson's disease. …
