The multimedia courseware developed using Flash offers strong interactivity, small file size, and easy online distribution, making it widely used in education and online teaching. With Flash’s ActionScript language, interactive courseware can be created, including flexible control of multimedia elements such as audio. This study proposes an adaptive voice-programming recognition method using multimedia technology and Flash. Sound signals are collected through an intelligent microphone and processed with Butterworth filtering and wavelet denoising. An improved adaptive threshold endpoint detection algorithm is applied to extract valid voice segments, followed by non-Gaussian measurement to distinguish voice features. Normalised ASD, MFCC, and other features are extracted, and blind deconvolution is used to further refine signal characteristics. An optimised KNN classifier is then employed for signal feature classification to achieve voice programming. Experimental results show that the system reaches an average accuracy of 93.32% for identifying a single student’s voice source and 83.05% for programming control tasks, under fixed equipment location and stable external conditions. Additional tests considering different locations, distances, dataset sizes, and users further confirm the feasibility, effectiveness, and robustness of the proposed voice-programming model.
