Creates a combined visualization showing a spectrogram with pitch contour overlaid. This is one of the most common Praat visualizations for voice analysis.
Usage
plot_spectrogram_pitch(
spectrogram,
pitch,
from_time = NULL,
to_time = NULL,
freq_max = 5000,
pitch_color = "blue",
pitch_floor = NULL,
pitch_ceiling = NULL,
title = "Spectrogram with Pitch",
...
)Arguments
- spectrogram

Additional arguments passed to plot methods
Examples
sound <- Sound$create_tone(frequency = 220, duration = 0.5)
spectrogram <- sound$to_spectrogram()
pitch <- sound$to_pitch()
# Basic combined plot
plot_spectrogram_pitch(spectrogram, pitch)
# Customize pitch range
plot_spectrogram_pitch(spectrogram, pitch,
pitch_floor = 75, pitch_ceiling = 500,
pitch_color = "red")
