An unwanted signal, known as noise, is added to speech and degrades the quality of signal. There are many speech enhancement techniques used for noise suppression such as spectral subtraction, wiener filtering, decision directed method etc. In this paper, we study some speech enhancement techniques, and proposed a hybrid filter using decision directed method and wiener filtering and then analyzed the intensity and pitch of noisy and enhanced speech in Praat tool, also compute the mean square error. Using hybrid filter, gets the better results and minimized the MSE of the signal.

Pitch-based speech perturbation measures using a novel GCI detection algorithm: application to pathological voice classification
Classical pitch-based perturbation measures, such as Jitter and Shimmer, are generally based on detection algorithms of pitch marks which assume the existence of a periodic pitch pattern and/or rely on the linear source-filter speech model. While these assumptions can hold for normal speech, they are generally not valid for pathological speech. The latter can indeed present strong aperiodicity,...
متن کاملProsody Toolkit: Integrating HTK, Praat and WEKA
A major hurdle in computational speech analysis is the effective integration of available tools originally developed for purposes unrelated to each other. We present a Python-based tool to enable an efficient and organized processing workflow incorporating automatic speech recognition using HTK, phonemelevel prosodic feature extraction in Praat and machine learning in WEKA. Our system is extens...

We provide a user-friendly automatic phonetic alignment tool for continuous speech, named EasyAlign. It is developed as a plug-in of Praat, the popular speech analysis software, and it is freely available. Its main advantage is that one can easily align speech from an orthographic transcription. It requires a few minor manual steps and the result is a multi-level annotation within a TextGrid co...

متن کاملVocale - A Semi-Automatic Annotation Tool for Prosodic Research
Large annotated speech corpora are a critical component of research in prosody. The classification of languages according to their speech rhythm, for example, requires a great number of annotated sentences by different speakers in different languages. We have developed Vocale, a tool for the semiautomatic annotation of vocalic and consonantal parts of speech because in recent models these units...
