Using speech recognition for packaging design is an effective way to enhance designers’ creative inspiration. Based on speech recognition technology, this paper constructs a speech recognition model with speech pre-emphasis, Hamming window split-frame plus window, and MFCC feature parameters and evaluates and analyzes the model. Then, the package design techniques and the functions of package graphics are explained in detail, and the quantitative analysis of data from package design techniques and package graphics design is carried out using the speech recognition model. The speech recognition model can recognize sixteen package design techniques in package design techniques, and the maximum and minimum recognition rates are 33.53% and 18.6%, respectively. The speech recognition model can recognize thirteen packaging graphic design keywords in packaging graphic design, with maximum and minimum recognition rates of 40.51% and 23.88%, respectively. Based on the speech recognition model, various packaging design techniques can be effectively recognized, which is conducive to enhancing designers’ inspiration in creating product packaging and promoting more innovative product packaging graphics.
