Speech noise reduction algorithm
WebOne of the objectives of this book is to present in a common framework an overview of the state of the art of noise reduction algorithms in the single-channel (one microphone) case. The focus is on the most useful approaches, i.e., filtering techniques (in different domains) and spectral enhancement methods. WebRecently, Siemens introduced a noise-management system in its high-end device that includes a noise-reduction algorithm targeted at non-speech transient sounds. In brief, …

WebThis structure allows the speech cloning system to pronounce special words. In addition, the preprocessing structure was improved by introducing a novel feedforward network, trained using a smaller computational cost, improving the training efficiency. Finally, we implemented a multi-algorithm speech-denoising module for noise reduction of the ... WebMay 1, 2024 · The phase inversion method is an acoustic measurement technique that provides access to the speech and noise signals separately at the hearing aid output. This method is based on making two recordings where the phase of one signal is inverted between the measurements.
WebOct 12, 2024 · One objective way to evaluate the effect of noise reduction algorithms in hearing aids is to measure the increase in signal-to-noise-ratio (SNR). To this end, Hagerman and Olofsson presented a method where multiple recordings take place and the phase of one signal is inverted between the measurements. WebFeb 14, 2011 · In this paper, a short-time objective intelligibility measure (STOI) is presented, which shows high correlation with the intelligibility of noisy and time-frequency weighted …
WebMay 19, 2015 · This is designed to facilitate the development of noise reduction algorithms as applied to speech acquired from a variety of sources including microphone arrays. Broadly, speech is composed of voiced and unvoiced parts, for example the word six being spoken as a phonetically as the four phonemes /s/ /ih/ /k/ /s/, with the two /s/ phones … WebTo improve the signal-to-noise ratio, the speech recorded at the terminal is often passed through noise reduction algorithms with non-linear and time-variant processing. However, such algorithms may also audibly degrade the speech quality of the transmitted signal, particularly when the background noise is time-variant or non-stationary.
WebSep 1, 2015 · Whether this phenomenon is similar for the effect of a noise reduction algorithm on speech quality still needs further investigation. In order for a noise reduction algorithm to be adopted by the users, it should do two things: increasing intelligibility and at the same time keeping or improving the perceived quality. An algorithm might improve ...
