This paper presents two new algorithms for robust speech pause detection (SPD) in noise. Our approach was to formulate SPD into a statistical decision theory problem for the optimal detection of noise-only segments, using the framework of model-based speech enhancement (MBSE). The advantages of this approach are that it performs well in high noise conditions, all necessary information is availa...

The requirements of real-time signal processing dictate that the audio must be completely processed before subsequent segment may received. This is done in order to achieve those requirements. highlights how important it create methods are not just quick but also accurate. I describe many ways for signals real time within scope this thesis. publications being presented cover a wide range issues...

Age affects hearing and cognitive abilities. Older people, with and without hearing impairment (HI), exhibit difficulties in hearing speech in noise. Older individuals show greater difficulty in segregating target speech from distracting background noise, especially if the noise is competing speech with meaningful contents, so called informational maskers. Working memory capacity (WMC) has prov...

OBJECTIVES In order to understand the communicative abilities of hearing impaired children in noisy situations and their communication problems, this study was undertaken to examine speech recognition at different background noise levels, and to compare how context cues in noisy situations affect speech recognition. METHODS Thirty-four children with severe/profound hearing impairment were enr...

Differences in understanding speech in noise among hearing-impaired individuals cannot be explained entirely by hearing thresholds alone, suggesting the contribution of other factors beyond standard auditory ones as derived from the audiogram. This paper reports two analyses addressing individual differences in the explanation of unaided speech-in-noise performance among n = 438 elderly hearing...

OBJECTIVES New signal processing technologies have recently become available for Baha® sound processors. These technologies have led to an increase in power and to the implementation of directional microphones. For any new technology, it is important to evaluate the degree of benefit under different listening situations. METHODS Twenty wearers of the Baha osseointegrated hearing system partic...

A robust feature extraction technique for phoneme recognition is proposed which is based on deriving modulation frequency components from the speech signal. The modulation frequency components are computed from syllable-length segments of sub-band temporal envelopes estimated using frequency domain linear prediction. Although the baseline features provide good performance in clean conditions, t...

The disorders of voice and speech in Parkinson’s disease (PD) result from involvements in several subsystems including respiration, phonation, articulation, and prosody. We investigated the feasibility of acoustic measures for the identification of voice and speech disorders in PD, using a quick vocal test consisting of sustained phonation, diadochokinetic task, and running speech. Various trad...

OBJECTIVES Repeated testing of speech perception is unavoidable in evaluating the benefits of hearing aids and auditory rehabilitation, but procedural and content learning due to repeated test administration can masquerade as a general improvement in speech perception. A previous study of the speech reception threshold (SRT) in quiet reported procedural learning that was sufficiently large to c...
