Sathe M.Tech. Student Dept. Of Electronics and Telecommunication Engineering, TPCT’s college of engineering, Osmanabad, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - Analysis Modification Synthesis (AMS) plays a key role in many audio signal processing applications, separating the audio stream into time intervals with speech activity and time intervals withoutspeech. Manyfeatureshave been introduced into the literature that reflecttheexistenceof language. Therefore, this article presents a structured overview of several established speech enhancement features targeting different characteristics of speech. Categorize features in terms of their exploitable properties. B. Evaluate performance in a background noise environment, different input SNR categories, and some dedicated functions. Our analysis shows how to select promising VAD features and find reasonable tradeoffs between performanceandcomplexity. To estimate clean speech usingtheFastFourierTransform(FFT), we emphasize the noise spectrum estimated during speech, subtract it from the noisy speech spectrum, and consider the average amplitude of the clean spectrum. and tried to develop a new method to minimize the spectrum of loud sounds. The noise reduction algorithm uses MATLAB software to semi- duplicate the noisy speech data (overlap-add processing) and use FFT to calculate the corresponding amplitudespectrum to remove noise from the noisy speech. and performed by reversing the audio in time. Reconstructed with the Inverse Fast Fourier Transform (IFFT). Key Words : Analysis Modification Synthesis (AMS), Inverse Fast Fourier Transform (IFFT), Fast Fourier Transform (FFT) etc. 1.INTRODUCTION An important goal of speech communication systems is to transmit speech signals in a way that is correctly understood by the recipient. Examples can be found in the field of telephonyandpublic addresssystems.Unfortunately, speech intelligibility can be affected by background noise. For example, poor speech intelligibility can be disruptive during a telephone conversation, but potentially dangerous in the context of a toll collection system voice alarm. as shown. At 1, background noise from either side of the communication channel can impair speech intelligibility for near-end listeners. In otherwords, noisecancomefrom both the far end and the near end. To eliminate the negative effects of far-end noise, we usually apply single-channel noise reduction algorithms (see [1] for an overview). However, speech can also be preprocessed before playback to make it more audible in the presence of near-end background noise, which is the focus of this work. There are many ways to break free from ringing signals. Telephones are increasingly used in noisy environments such as cars, airports, streets, trains and stations. Now let's pull back the noise using the spectral minimization method. The purpose of this work is to build a real-time systemthatcanreducethe background caused by audio signals. This process is called speech enhancement. In many language systems, the background lowers the language standard. It is usually difficult to remove noise without distorting the audio. Therefore, the performance of speech enhancement devices is limited between speech distortion and noise reduction. from the loud sound spectrum. In this method, the following he assumes three situations. Channels are on the market in which the sound adds to the audio signal and the sound is uncorrelated. During thiswork,weusedspectral subtraction techniques to try to reducenoisespectrum estimationerrors and improve corrupted speech. We proposed a method that was tested on a real language data framework in the MATLAB environment. Real speech signals from the speech data database were used for various experiments. We then propose a technique to reduce the difference between the estimated noise spectrum and the noise spectrum. In general, we find that systems withonlyonemedium perform under the most difficult conditions in response to varying audio data and unwanted noise, where advanced noise intelligence is not available. Usually, when the speech is polite, men consider the noise to be steady. They usually tolerate non-stationary noise during periods of speech activity, but in practice the power of speech signals decreases dramatically when the noise is non-stationary. 2.

The single we use is considered the conclusion of phantom subtraction. This guy works within the Epidemic Bureau and trusts Phantom of Aid to be mentioned when Sound Phantom and Noise Phantom are added. The action is shown in the image below and in two main parts It has been constructed. B. Noise estimation A minimum statistical noise estimate is used to estimate the background noise. where * means the convolution process and is the bias value Background spectrum estimation. Subtract noise spectrum from noisy speech Fig.1 Conventional Spectral Subtraction Figure 1 shows the conventional spectral subtraction using the overlap add method. The AMS method [6], shown in Figure 1, is an efficient method of signal amplification. AMS uses the following procedure: We first frame the input audio signal using a suitable window function, then perform his STFT of the windowed frames using some frame shifts. The third is the inverse Fourier transform, and the fourth is signal acquisition by the overlap-and-addition (OLA) method [7]. Consider an additive noise scenario like Equation (1). One equation in a row. x(n) =s(n) +N(n) (1) where x(n), s(n), and N(n) are windowed samples of noisy speech, clean speech, and spurious noise, respectively. n Discrete time index. Since speech signalsareinherentlynon- stationary, speech in AMS frames is processed over short frame durations using short-term Fourier transforms. From the STFT definition, the spectrum of noise degrades speech. Not all spectral magnitude values appear to bepositiveafter subtraction. There are several ways to remove unwanted components. An inverse Fourier transform using the phase components directly from the Fourier transform unitandan overlap-add are then performed to reconstruct the speech estimate in the time domain. The basic concept is to minimize the noise of the input noise signal. (2),(3) Unfortunately, we don't know the exact level of the noise signal, so we reduce the amplitude and leave the level of X unchanged. After subtraction, the spectral magnitude is definitely not positive. There are several waystoremovethe negative component present in the spectrum.Toconvertthe frequency-domain signal to the time-domain signal, the phase of the noisy speech signal is combined with the processed amplitude spectrum and an inverse discrete Fourier transform (IDFT) is initiated. time domain.

Conventional Spectral Subtraction Fig. 3. Short Time Fourier Transform of speech Enhancement incorporating Overlap-Add Processing 3. Experimental Evaluation There are many public or commerciallyavailablespeech and noise databases for evaluating speech enhancement algorithms. In this work, we used the language corpus database NOIZEUS [7] for our experiments. The basic premise of databases like NOIZEUS is to provideresearchers with more realistic noise recordings at various input SNRs. The speech corpus consists of 30 phonetically balanced her IEEE sentences from 6 speakers (3 male, 3 female). The experiments used corpus noise stimuli constructed by real- time noise environments at different input SNRs, such as airport, chatter, car, restaurant, station, and train background noise. Thirty sets of mean values for the NOIZEUS corpus were calculated for each treatment type, noise type, and input SNR. C. Complex objective measures Speech quality is also assessed by the Composite Objective Scale (COM). Several objective measures of composite quality are derived from multiple regression analysis. We compared the spectral behavior of representative features from time-frequency spectrogram analysis. Capturing an enhanced audio signal compared to a noisy spectrum at various input SNRs such as 0dB, 5dB, 10dB, 15dB without exploiting the temporal contextofthe audioinformationwas observed. 4. Spectrogram analysis Spectrograms, in particular, have different colors. Here red and yellow indicate two different intensity phases. The entire loud audio input signal is full of extreme intensity colors because yellow is loud, red is high in the center intensity, and black is a weak crowd with little intensity. Especially during quiet times of the resulting audio signal, the noise result can be more.

Spectrogram of pure audio signal We compared the spectral behavior of representative features from time-frequency spectrogram analysis. Capturing an enhanced audio signal compared to a noisy spectrum at various input SNRs such as 0dB, 5dB, 10dB, 15dB without exploiting the temporal context of the audio information was observed. To illustrate the proposed performance, consider the spectrogram plot in Figure 5. Spectrograms are shown for clean speech (5.5a) and noisy speech (5.5b, 5.5e) with input SNRs of 0 dB and 5 dB, respectively. Figure 5.5b shows that the low frequencies, where most of the audio energy resides, are corrected more than the high frequencies. For speech stimuli constructed with the proposed method (5.5d), a significant reduction in noise is observed at certain low frequencies compared to the Mod-SpecSub method (5.5c). Fig. 5.

CONCLUSIONS In thisarticle, we summarized and analyzedseveral spectral subtraction functionsusingdifferentnoisyenvironments.We have outlined established approaches for the purpose of classifying features according to the language extension properties used. Our analysis showed that performance was taken into consideration. We identified objectiveevaluations such as the Perceived Speech Quality Score (PESQ), Csig, Cbak, overall signal quality Covl and loss of signal context as important aspects for improving speech enhancement performance. .
