WebJan 19, 2024 · So keeping the window this much smaller we won’t lose any phoneme while classifying. The frame (window) overlap can vary from 25% to 75% as per your need, generally, it is kept 50% for speech recognition. In our spectrogram calculation, we will keep the window duration 20ms and an overlap of 50% among the windows. WebThe spectrogram function has a matrix containing either the power spectral density (PSD) or the power spectrum of each segment as the fourth output argument. The power spectrum is equal to the PSD multiplied by the equivalent noise bandwidth (ENBW) of the window.
