Pronuntiatio was the discipline of delivering speeches in Western classical rhetoric.

It is the one of five canons of classical rhetoric (the others being inventio, dispositio, elocutio, and memoria) that concern the crafting and delivery of speeches.

As with memoria, the canon that dealt with the memorization of speeches, pronuntiatio was not extensively written about in Classical texts on rhetoric. Its importance declined even more, once the written word became the focus of rhetoric, although after the eighteenth century it again saw more interest. In public speaking today, it may be somewhat over-emphasized, but that is probably more because other parts of rhetoric are downplayed.

Rhetoricians laid down guidelines on the use of the voice and gestures (actio) in the delivery of oratory. There were instructions on the proper modulation of the voice (volume and pitch), as well as the phrasing, pace, and emphasis of speech. Also covered were the physical aspects of oration: stance, gestures, posture, and facial expressions. There was also the concept of exercitatio (or practice exercises) that enabled speakers to both memorize their speeches and to practice their delivery.

This excerpt from Quintilian's Institutio oratoria provides an example of the types of advice provided by rhetoricians:

"The head, being the chief member of the body, has a corresponding importance in delivery, serving not merely to produce graceful effect, but to illustrate our meaning as well. To secure grace it is essential that the head should be carried naturally and erect. For a droop suggests humility, while if it be thrown back it seems to express arrogance, if inclined to one side it gives an impression of languor, while if it is held too stiffly and rigidly it appears to indicate a rude and savage temper." (Institutio oratoria, XI iii 68-69, translated by H. E. Butler, Loeb Classical Library, 1922)

While the content, structure, and style of oration were (and continue to be) the most important elements of oratory, there is no doubt that effective delivery enhances its persuasive power, and that poor delivery detracts greatly from its intended effect.
