Week 7
We worked on coding for our speech recognition program, using MATLAB. Additional toolboxes, specifically the signal processing toolbox, needed to be downloaded for use with MATLAB.
We continued using a source that can be found in week 3's post (the third source). Several MATLAB source files are given. The source file for testing the incoming voice commands calls the matching function, which in turn calls the extracting function. The extracting function returns a vector for the input. The training function also calls for extraction. However, the main source file of the word recognition programs is for speech. It calls the other functions (recording, training, extracting, testing, and matching) and keeps track of the vocabulary that is trained into the program.
While running these source files in their original form, some errors occurred with loading data into the MATLAB workspace. Adjustments in the code have to be made to suit our needs. This includes having code to tell the computer what to do once it recognizes a word. The original program only recognizes and classifies what the user has said.
