Get Interval Statistics for All Intervals (Batch) — get_textgrid_interval

Compute statistics (start, end, duration, label) for all intervals in a tier in a single call, instead of a manual loop. Returns a data frame ready for analysis.

Usage

get_textgrid_interval_stats(textgrid, tier)

Arguments

textgrid: A TextGrid object
tier: Tier number (1-based) or tier name

Value

Data frame with columns: - `index`: Interval index (1-based) - `label`: Interval label - `start`: Start time (seconds) - `end`: End time (seconds) - `duration`: Duration (seconds)

Examples

tg <- TextGrid$create(0, 1, "words")
tg$insert_boundary(1, 0.5)
tg$set_interval_text(1, 2, "hello")
stats <- get_textgrid_interval_stats(tg, tier = 1)

# Analysis with base R
voiced <- stats[stats$label == "hello", ]
mean(voiced$duration)
#> [1] 0.5
