Introduction

Gender classification through sound is a complex challenge in the field of sound recognition. In this study, researchers develop applications that can distinguish male and female sounds using Artificial Neural Networks (ANN) types of back propagation. The process begins by taking analog sound signals and converting them into digital signals using Adobe Audition software. Next, this signal is processed using the Linear Predictive Coding (LPC) method to get the LPC coefficient. This coefficient is then processed further with Fast Fourier Transform (FFT) and Chirp Z Transform (CZT) to produce better signals. The output of the CZT is then processed using a JST Back Propagation to classify gender based on sound. In this study, the training data consisted of 25 male votes and 25 female votes, while testing data included 5 male votes and 5 female votes, which resulted in an accuracy of 90%.

Analysis of the Gender Classification Process

The sound recognition process for gender classification involves several important stages to ensure high accuracy. First, the conversion of analog signal to digital is very crucial, because only with digital signals further analysis can be done. This process allows sound processing to eliminate noise and isolate relevant frequencies. The use of the LPC method is one of the common techniques in voice processing because it is able to predict the characteristics of sound signals well. With LPC, we can get a coefficient that describes the sound spectrum which can then be used to detect differences between male and female voices.

After that, further processing using FFT and CZT is important to improve sound signal quality. FFT helps in signal transformation from time to the frequency domain, while CZT provides better capabilities in analyzing signals on certain frequencies that may be more relevant in gender identification. At the end of this process, the neural network of artificial back propagation plays an important role in gender classification based on sound. By training the model using a balanced data between male and female sounds, the model can learn and identify the patterns that distinguish the two types of sounds. The result showing 90% accuracy indicates that this approach has a great potential to be applied in a broader sound recognition application.

Benefits and Applications

Gender classification through sound has a variety of useful applications. For example, in a security system, this technology can be used for sound verification based on sound. In the field of marketing, sound analysis can help in understanding the audience preference based on gender. In addition, in voice assistant technology, the ability to recognize the gender of users can improve user experience by providing a more personal response. Thus, this research not only presents technology solutions for gender classification through sound, but also opens opportunities for further development in the field of more accurate and efficient sound recognition. With advanced technological advances, it is hoped that this application will grow and provide benefits to the wider community.
