Faced with a new set of issues in a globalized world, governments at all levels are increasingly realizing that no matter how good their policies are, they will not be able to conduct and effectively implement them if their public do not understand and support them. As a result, they're seeking for new or enhanced models and techniques for better informing and involving citizens in policymaking. The relevancy of the participation given by the citizens will enhance the way of living of a certain community as they hold the power of being vocal and resilient. They should be aware, however, that reaching a compromise or consensus can be difficult at times, because the participants' readiness, as well as their openness to alternative points of view, vary greatly. However, the public dialogue serves as a democratic school, where citizens learn to fulfill their civic responsibilities via hands-on experience.
inflection: a modulation of the voice; change in pitch or tone of voice
a intonation is when your voice moves around almost melodically in connected speech, i.e. your pitch changing throughout a phrase, an example from the dictionary is:
intonation: the opening phrase in a gregorian chant, usually sung by one or two voices.
intonation: the manner of producing musical tones, specifically the relation in pitch of tones to their key or harmony.
so really it means that intonation is a sort of intentional way of pitching your voice throughout a whole phrase up and down while an inflection is bringing your voice higher and only higher through a phrase.
