Abstract:

The stage of extracting the features of the speech file is one of the most important stages of building a system for identifying a person through the use of his voice. Accordingly, the choice of the method of extracting speech features is an important process because of its subsequent negative or positive effects on the speech recognition system. In this paper research we will analyze the most popular methods of speech signal features extraction: LPC, Kmeans clustering, WPT decomposition and MLBP methods. These methods will be implemented and tested using various speech files. The amplitude an

Abstract:

AbstractThis article presents an overview of the single-channel dereverberation methods suitable for distant speech recognition (DSR) application. The dereverberation methods are mainly classified based on the domain of enhancement of speech signal captured by a distant microphone. Many single-channel speech enhancement methods focus on either denoising or dereverberating the distorted speech signal. There are very few methods that consider both noise and reverberation effects. Such methods are discussed under a multistage approach in this article. The article concludes with a hypothesis that

Abstract:

Although the behavioral pure-tone threshold audiogram is considered the gold standard for quantifying hearing loss, assessment of speech understanding, especially in noise, is more relevant to quality of life but is only partly related to the audiogram. Metrics of speech understanding in noise are therefore an attractive target for assessing hearing over time. However, speech-in-noise assessments have more potential sources of variability than pure-tone threshold measures, making it a challenge to obtain results reliable enough to detect small changes in performance.

Abstract:

Classification of electroencephalography (EEG) signals corresponding to imagined speech production is important for the development of a direct-speech brain–computer interface (DS-BCI). Deep learning (DL) has been utilized with great success across several domains. However, it remains an open question whether DL methods provide significant advances over traditional machine learning (ML) approaches for classification of imagined speech. Furthermore, hyperparameter (HP) optimization has been neglected in DL-EEG studies, resulting in the significance of its effects remaining uncertain. In this st

In language evolution research, the use of computational and experimental methods to investigate the emergence of structure in language is exploding. In this review, we look exclusively at work exploring the emergence of structure in speech, on both a categorical level (what drives the emergence of an inventory of individual speech sounds), and a combinatorial level (how these individual speech sounds emerge and are reused as part of larger structures). We show that computational and experimental methods for investigating population-level processes can be effectively used to explore and measur

This paper aims to promote ‘disfluency awareness’ especially in the field of phonetics –which has much to offer in the way of increasing our understanding of these phenomena. Two broad claims are made, based on analyses of disfluencies in different corpora of spontaneous American English speech. First, an Ecology Claim suggests that disfluencies are related to aspects of the speaking environments in which they arise. The claim is supported by eviden

Background: Stuttering is an organic process utterance condition. This utterance condition is broken by prolongation of sounds and repetitions of part words and phrases. Speech constitution strategies facilitate the client to use a new way of oral communication in stutters. Objective: to determine the effects of prolongation of speech and syllable time speech on reduction of severity of stuttering in stuttering patients. Methods This Randomized clinical trial study design was conducted in National Institute of Rehabilitation Medicine Islamabad. A total of n=30 participants of both gender havin

Abstract:

In order to investigate how to recognize English words and speech corpus, an English vocabulary and English speech recognition model based on deep learning algorithm was proposed. Through recommending key technical problems and solutions based on deep learning algorithm, how to realize the recognition of English vocabulary and speech corpus was investigated. In the research, the accuracy of the method on the English vocabulary and speech corpus recognition based on the deep learning algorithm increased 79% over the previous methods. Combined with the principle of the deep automatic encoder and

Abstract:

Due to the increased customer demand for various applications in various fields, service robots are becoming very popular. Human Robot Interaction (HRI) is very essential for the good performance of the home service robot. A robot can be controlled by many methods and here the robot is controlled by voice commands which are given orally. The robot must be able to perform various tasks such as speech source localization, source separation and classification etc. The robot must be capable to identify the source accurately. The speech recognizer and a speaker classifier are used to improve the pe

<strong>Background</strong> The development of automatic tools based on acoustic analysis allows to overcome the limitations of perceptual assessment for patients with head and neck cancer. The aim of this study is to provide a systematic review of literature describing the effects of oral and oropharyngeal cancer on speech intelligibility using acoustic analysis. <strong>Methods</strong> Two databases (PubMed and Embase) were surveyed. The selection process, according to the preferred reporting items for systematic reviews and meta‐analyses (PRISMA) statement, led to a final set of 22 article

Abstract:

Speech recognition plays an important role in the field of human-computer interaction through the use of acoustic sensors, but speech recognition is technically difficult, has complex overall logic, relies heavily on neural network algorithms, and has extremely high technical requirements. In speech recognition, feature extraction is the first step in speech recognition for recovering and extracting speech features. Existing methods, such as Meier spectral coefficients (MFCC) and spectrograms, lose a large amount of acoustic information and lack biological interpretability. Then, for example,

Materials and Methods: Speech evaluations were performed on 23 patients with fixed labial appliances. Evaluations were performed immediately prior to appliance insertion, immediately following insertion, and 1 and 2 months post insertion. Baseline dental/skeletal variables were correlated with the ability to accommodate the presence of the appliances. Results: Appliance effects were variable: 44% of the subjects were unaffected, 39% were temporarily affected but adapted within 2 months,

Abstract:

Detecting and interpreting individual acoustic cues to identify features that distinguish among speech sounds is thought to play a key role in automatic speech processing, modeling human speech perception, detecting and diagnosing speech disabilities (and tracking the effects of treatment for those disabilities), and studying cross-language differences. The individual acoustic cues form a bridge between transcription using phonemic symbols (phonemes) and raw acoustic measurements from the signal and allow the analysis to capture systematic language-related differences in how words are pronounc

Objective To investigate the effects of breathy voice sources on ratings of hypernasality using synthesized speech. Methods Speech samples were obtained from children with cleft palates who demonstrated varying degrees of hypernasality and from a child with a voice disorder. Sources with 6 degrees of breathiness were created: a breathy source and five synthesized sources with lowered harmonics-to-noise ratio (HNR) values by the addition of impulses. These sources and each original (clear) source were combined with three kinds of filters: mild, moderate, and severely hypernasal. Consequently, 2
