Focusing on...the voice...? In Potions class? What on earth could this lesson be about? Thought Heather. It was a rather...odd...topic to discuss in this class. After all, the voice isn't really the first thing that would come to mind in a class such as this. However, it would be a lot different in a class like Charms or Transfiguration even, as those could have some potential spell revolving around it. Whether it was through amplification or nullifying the resonance of our vocal folds, there were spells in both of those fields in one form or another that could deal with the complex process of speech patterns.

Thinking about it, the question posed was a rather simple one, as there were several ways to change the voice, both magical and nonmagical. Raising her hand, signet ring sparkling in the light, Heather stated with confidence "Professor, there are many different ways in which we can change our vocal patterns. Magically one could cast Sonorus, which would amplify the voice. Or, to soften it the caster could use Quietus." She took a brief pause before speaking again with the reasoning behind why someone would want to do either of these. "A person would want to amplify their voice if they were in a large area such as an arena. And then on the other hand, if you wanted to do the opposite, to try and not be heard other than by the person next to you, you would cast the counter charm to Sonorus."
