from aligned_textgrid import SequenceTier, TierGroup, Word, Phone

word_tier = SequenceTier([
    Word((0,10, "the"))
])
phone_tier = SequenceTier([
    Phone((0,5,"DH")),
    Phone((5,10, "AH0"))
])

tier_group = TierGroup([word_tier, phone_tier])

dog = Word((10, 25, "dog"))
dog.append(Phone((10,15, "D")))
dog.append(Phone((15, 20, "AO1")))
dog.append(Phone((20,25, "G")))

word_tier.append(dog)
