It is important to note that presidential speech-making has evolved, starting from limited avenues in the early republic to the rise of mass media and communication technology.
From the provided information, it is clear that presidents use speeches as vital tools to celebrate, express national emotion, engage in policy discourse, and persuade the populace. The impact and frequency of these speeches vary by administration, subject, and historical context. Therefore, identifying the president giving the most Oval Office speeches would require specific record-keeping that is not referenced directly in the provided sources.
