Back to the 911 call: Below is a link to a very good article from the FBI Law Enforcement Bulletin entitled
911 Homicide Calls and Statement Analysis: Is the Caller the Killer?

In this article they look at key elements in 911 calls to determine deception. They performed a study of 911 calls where the outcome of the case is known.
According to the article, the strongest indication of guilt is when extraneous information is given instead of relevant facts. The second strongest indication of guilt is self-interruption by the caller and changes in the direction of the topic.
Although Misty was the primary caller in the 911 call, forget her for now. She has so many deceptive indicators that it's hardly worth discussing.
So, if you look at Ron and his voice modulation, he certainly seems to have the loud volume, fast speed, varied pitch and emotional tones. I only question whether they were real or whether he was intentionally throwing his voice to a high pitch. It simply didn't sound genuine to me, but that's only a matter of opinion. Since his voice modulation is so controversial, take a look at what Ron actually said.
Here is what Ron said when he talked to the 911 dispatcher:
"I just got home from work, my five-year-old daughter is gone - I need someone here now."
It looks to me like his first order of business was establishing an alibi. This was extraneous information.
Then his next statement is:
"If I find whoever has my daughter before you all do, I'm killing them... I don't care - I will spend the rest of my life in prison... you can put that on the recording... I don't care."
This is absolutely too much information and not relevant to helping the dispatcher with the task at hand. It also sort of changes the direction of the topic doesn't it? I mean, the topic is finding his daughter, not about what he is going to do to someone and whether he cares if he goes to prison.
Ron is then asked about a description of the pajamas she was wearing and his response was:
"I don't f%$ know!"
The level of cooperation is clearly very low. He's not even trying to respond to the dispatcher's inquiries. Later in the call he even says,
"F her date of birth."
You then have another outburst by Ronald about killing someone and going to prison and so on it goes.
What is very lacking in the 911 call is Ron's lack of cooperation, non-response to the dispatcher inquiries, resisting full cooperation, anger and threats. In the transcript of the 911 call, I don't see any accurate, concise, clear or relevant information he gave to the dispatcher about HaLeigh. None.
Something else that is seriously lacking in this call is Ron's
fear for his daughter.
To sum up my point, it is not always how someone says something, but also what they say and what they don't say.
