Heating up the conversation, getting loud, intense, guttural, and very charged comes when you speak with your intention from the lower chakras. You can really start cooking if you put your intention on the orange chakra; and you're an unstoppable ball of screaming energy when you focus on the root chakra. Then if you draw your energy back up to the heart, throat, mind's eye, or crown, you speak, respectively with more and more slow, serene, more highly-calculated, "higher source" area.

In communicating through voice, you draw from all chakras, independently, at different times.

Each chakra has the equal amount of deliberateness, sincerity, and intention, but drawing from different chakras to communicate will vary the cadence, speed, tonal inflection, and vigorousness of body language and hand gesturesde. Depending on the listener or audience, some chakras will be more poignant, convincing, and communicate the message more clearly. For example, with an easily distracted youthful teen, the wild, rockstar-like, deep guttural, quick-movement animation from the root chakra will instantly draw their intention. However, to an elderly person, or very sensitive and wise person, such an explosive interaction would frighten them or cause them to deactivate as a listener. In the case of an older and/or calmer person communicating from the throat and above chakras would be the most effective circuitry.

Experiment with different chakra schematics, but then develop an ability to assess which chakra locus of communication derives the most effective message beforehand. Being able to study a person like the lion and then commit with curious intensity like the shark to whatever chakra communicational level is appropriate at that time is your key to being not just an effective, but a synergistic, compelling, alluring, and captivating communicator.
