sequences.tiers.SequenceTier(tier=SequenceList(), entry_class=None)A sequence tier
Given a praatio IntervalTier or list of Intervals, creates entry_class instances for every interval.
In addition to the attributes and methods described below, the attributes and methods from TierMixins and WithinMixins are also available.
Parameters

|---|---|---|---|
| tier | list[Interval] | list[SequenceInterval] | IntervalTier | Self |
A list of interval entries. Defaults to SequenceList(). |
SequenceList() |
| entry_class | Type[SequenceInterval] | The sequence class for this tier. Defaults to SequenceInterval. | None |
