Archives for spectrogram
For visualising signals into an image, we use a spectrogram that plots the time in the x-axis and frequency in the y-axis and, for more detailed information, amplitude in the z-axis. Also, it can be on different colors where the density of colors can be considered the signal’s strength. Finally, it gives you an overview of the signal where it explains how the strength of the signal is

The actual environment of Keyword recognition is quite more complex than this demonstration. This article focuses on knowing the basic idea used behind the keyword recognition for short audio files of one second. As the convolutional networks outperform when it comes to image-based classification tasks, we are leveraging this behaviour of convolutional neural networks to the keyword recognition/classification task.

Data science deals with multiple formats of data. At the basic level, we start with the CSV and Excel files. As we dig deeper into it, every source of information can be considered as data, no matter what kind of information it is. Different kinds of data such as images, video or audio can tell…

Machine Learning has found its application across a number of domains that involve mimicking the complexities and senses of human beings. Computer Vision and Speech synthesis have been around since the late 1960s and have exponentially improved over time — especially in the last few years. Today, we will focus on Speech Synthesis which is…
