Word and Phone Intervals

The tier repeats the Orthography words and places an internal media interval after each word. When first created, word boundaries are distributed across the record's media segment. Editing Orthography updates the words while retaining existing timings when the word count permits; if the count changes, timings are redistributed across the segment.

Changing a word interval also updates the record media segment to span the word intervals. If Phone intervals is present, its timings are adjusted with the changed word boundaries.

The tier repeats timed elements from IPA Actual, adds an internal media interval after each phone, and uses a slash between words. It requires Word intervals so phones can be assigned to word boundaries.

Editing IPA Actual updates the phone labels. Existing intervals are retained when the number of timed elements in a word is unchanged; otherwise Phon redistributes them evenly within the word interval. Changing a Word interval scales its aligned phone intervals to the new word boundary.

In Speech Analysis, open the menu for a session interval tier and select Import into Word intervals... or Import into Phone Intervals.... The import dialog supplies conversion options and can apply the import to all records or a selected record range.

The TextGrid import wizard can also map TextGrid tiers to these targets. Importing Phone intervals creates Word intervals first when needed.
