This paper presents new adaptive filtering techniques used in speech enhancement system. Adaptive filtering schemes are subjected to different trade-offs regarding their steady-state misadjustment, speed of convergence, and tracking performance. Fractional Least-Mean-Square (FLMS) is a new adaptive algorithm which has better performance than the conventional LMS algorithm. Normalization of LMS ...

Low-bit-rate speech coding, at rates below 4 kb/s, is needed for both communication and voice storage applications. At such low rates, full encoding of the speech waveform is not possible; therefore, low-rate coders rely instead on parametric models to represent only the most perceptually-relevant aspects of speech. While there are a number of different approaches for this modeling, all can be ...

PURPOSE To study the effect of noise on speech rate judgment and signal-to-noise ratio threshold (SNR50) at different speech rates (slow, preferred, and fast). RESEARCH DESIGN Speech rate judgment and SNR50 tasks were completed in a normal-hearing condition and a simulated hearing-loss condition. STUDY SAMPLE Twenty-four female and six male young, normal-hearing participants. RESULTS Spee...

Function words in casual speech can be made to disappear by slowing the surrounding speech rate [1]. The current study explored the domain generality of this disappearing word effect, asking whether function words can be made to disappear by manipulating temporal properties of nonspeech context. Stimuli were short word sequences (e.g., minor or child) appended to precursors that were either spe...
