What feature would you like added?
Right now, it is only possible to fuse intervals leftwards or rightwards, but impossible to split an interval. Thinking about how the SequenceInterval.split() could work:
Splitting
On timestamps
interval.split(at_times = [2.31, 2.35])
This should add new interval boundaries at the given times (with the interval's start and end time implicit). This example would result in 3 intervals.
On percentage time
interval.split(at_proportion = [0.2, 0.7]
This would place boundaries at 20% and 70% of the duration of the interval, resulting in 3 intervals.
On the subset
interval.split(on_subset = True)
This should, perhaps, be the default behavior. This would split the interval into sub-intervals based on the timestamps of its subset intervals.
Labelling
Explicit labels
interval.split(
at_proportion = [0.2, 0.7],
labels = ["a", "b", "c"]
)
Label Fun
def label_sequential(label, sequence_len):
label_rep = label * sequence_len
labels = [
f"{lab}-{num}"
for lab, num in zip(label_rep, range(sequence_len))
]
return labels
def label_rep(label, sequence_len):
label_rep = label * sequence_len
return label_rep
def label_blank(label, sequence_len):
label_rep = "" * sequence_len
return label_rep
interval.split(
at_proportion = [0.2, 0.7],
label_fun = sequential_number
)What would the use case be for this feature?
When creating new-sub-interval tiers based in analytical landmarks. E.g.
- Splitting an initial phrase interval into sub-phrases based on the presence of silences in the aligned word-tier.
- Splitting a word interval into morphemic components, based on timing in the phone tier.
- Splitting a phone interval into onset, target, offset components, based on acoustic measurements.
