Of course, it's true.
Lu Chuan rubbed his hands together, completing the voiceprint identification for four voices in one go was no easy task.
Moreover, this was Lu Chuan's first time conducting a voiceprint analysis.
He was somewhat inexperienced, and many details needed repeated analysis and deliberation.
For example, the second male voice showed signs of a long-term habit of eating peppers.
Although the second male voice had an accent from the southern Zhezhou, in reality, Zhezhou doesn't particularly have a strong habit of eating spicy food.
"Chili peppers are a stimulating food, and long-term consumption can cause some irritation to the vocal cords, leading to significant changes in a certain frequency of the voice."
The voiceprint analysis report produced by Lu Chuan didn't just contain conclusions; every conclusion process was detailed.
"Generally, people without special training won't reach extreme frequencies in their voice range."
