The Guided Visual Pitch Tracking (GVPT) is a Windows Presentation Foundation (WPF) application developed in C# to support voice task experiments in behavioral science, with a focus on precise real-time pitch detection and tracking. The software offers five distinct voice pitch tasks, each designed to evaluate different aspects of pitch control, including pitch sustainability, elevation, lowering, and continuous modulation. These tasks can be delivered through three guidance methods: no guidance, guidance at every pitch point, or guidance at key pitch-changing points, providing researchers with flexible options to tailor the experiment. Additionally, GVPT facilitates the recording of voice data at customizable sampling rates (44,100 Hz, 48,000 Hz, 88,200 Hz, and 96,000 Hz), producing datasets for thorough post-experiment analysis.
