Abstract This paper addresses robust front-end processing for automatic speech recognition (ASR) in noise. Accurate recognition of corrupted speech requires noise robust front-end processing, eg, voice activity detection (VAD) and noise suppression (NS). Typically, VAD

Text processing for text-to-speech systems in Indian languages.

Abstract To build a natural sounding speech synthesis system, it is essential that the text processing component produce an appropriate sequence of phonemic units corresponding to an arbitrary input text. In this paper we discuss our efforts in addressing the issues of

2-d processing of speech with application to pitch estimation.
free download

ABSTRACT In this paper, we introduce a new approach to two-dimensional (2-D) processing of the one-dimensional (1-D) speech signal in the time-frequency plane. Specifically, we obtain the shortspace 2-D Fourier transform magnitude of a narrowband

Facilitation or attenuation in the development of speech mode processing Tone perception over linguistic contexts
free download

ABSTRACT-Perceptual discrimination of Thai tones was tested in three contexts: normal speech, filtered speech, and musical sounds with speakers of Central Thai; speakers of Cantonese, a tonal language of similar complexity; and speakers of English. The inter-

Privacy Preserving Techniques for Speech Processing
free download

Abstract Speech is perhaps the most private form of personal communication but current speech processing techniques are not designed to preserve the privacy of the speaker and require complete access to the speech recording. We propose to develop techniques for

Interactions in bilingual speech processing
free download

Experiment 1 investigated whether properties of specific words bilinguals produce eg, cognate status influenced interactions between native (L1) and second language (L2) phonetic systems. Analysis of voice onset times (VOTs) revealed that bilinguals were

Voice signal processing for speech synthesis
free download

Abstract-Our goal was to build a software application capable to manipulate and analyse speech signal, extract characteristic parameters needed for speech synthesis and to enhance the speech quality. This article presents speech signal parameters used in

Management of auditory processing difficulties: A perspective from speech-language pathology
free download

In recent years, central auditory processing disorder (CAPD) has become a recognized clinical entity within the field of communicative disorders. More and more children are being diagnosed with CAPD or, in other cases, are described with behaviors that are compatible

Study of the influence of noise pre-processing on the performance of a low bit rate parametric speech coder.
free download

ABSTRACT This paper describes a prospective study of the contribution of a single-sensor noise pre-processing method, prior to coding, to the performance of a parametric low bit rate speech coder in adverse conditions. The 2.4 kbits/s vocoder we use estimates four

Speech pre-processing against intentional imposture in speaker recognition.
free download

ABSTRACT Recently, some large-scale text dependent speaker verification systems have been tested. They show that less than 1% Equal Error Rate can be obtained on a test set score distribution. So far, the majority of impostor tests are performed using speakers who

Performance evaluation of front-end processing for speech recognition systems
free download

Abstract Conventional speech feature extraction front-end algorithms suffer severe performance degradation in noisy environment, especially when there is a noise level mismatch between the training and testing environments. It is necessary to search for new

Applying natural language processing techniques to speech prostheses
free download

Abstract In this paper, we discuss the application of Natural Language Processing (NLP) techniques to improving speech prostheses for people with severe motor disabilities. Many people who are unable to speak because of physical disability utilize text-to-speech

Evaluating Prosodic Processing for Incremental Speech Synthesis.
free download

Abstract Incremental speech synthesis (iSS) accepts input and produces output in consecutive chunks that only together result in a full utterance. Systems that use iSS thus have the ability to adapt their utterances while they are ongoing. However, starting to

Real time speech processing for dichotic presentation for binaural hearing aids
free download

Abstract In case of sensorineural impairment, the reduced frequency resolution in the peripheral auditory system due to spread of masking of a frequency component by adjacent frequency components degrades speech perception. Speech processing by a bank of

MSc in Speech and Language Processing Dissertation: Automatic summarising based on sentence extraction: A statistical approach
free download

Abstract The present dissertation and project describes a system for automatic summarising of texts. Instead of generating abstracts, a hard NLP task of questionable e ectiveness, the system tries to identify the most important sentences of the original text, thus producing an

An approach to describe methods Of front end processing of Speech signal
free download

Abstract Speech is the most natural way of information exchange. It provides an efficient means of man machine communication using speech interfacing. Today significant part of speech recognition research is focused on speaker independent speech recognition
