Here is a quick prototype of the short time energy function in GNU Octave for a the speech sample “Mister Meryk”. The plot below shows the average magnitude of the phrase using a window size of 320 samples, calculated every 80 samples. Average magnitude function. Here is the code that I used to generate the [...] Signal processing algorithms are usually prototyped and tested using high level math tools such as MATLAB or Mathcad. These tools use a high level language that closely models actual mathematical equations. Tools like these include many built in math functions and utilities to plot results. MATLAB even has add-on packages that can [...] |
