textgrid

A small library which can parse TextGrid into json and json into TextGrid

Getting Started

On the server

Install the module with: npm install textgrid --save

var textgrid = require('textgrid');
textgrid.init(); // "init"

In the browser

Install the module with: bower install textgrid --save or,

Download the production version or the development version.

In your web app:

<script src="bower_components/textgrid/dist/textgrid.min.js"></script>
<script>
  var textgridAsJson = TextGrid.textgridToIGT(originalTextGridAsText);
</script>

In your code, you can attach textgrid's methods to any object.

<script>
var exports = Bocoup.utils;
</script>
<script src="bower_components/textgrid/dist/textgrid.min.js"></script>
<script>
var textgridAsJson = Bocoup.utils.textgridToIGT(originalTextGridAsText); // "init"
</script>

An example of what you can do with the result.

var textgrid = TextGrid.textgridToIGT(text);
if (textgrid.isIGTNestedOrAlignedOrBySpeaker.probablyAligned) {
	for (itemIndex in textgrid.intervalsByXmin) {
		if (!textgrid.intervalsByXmin.hasOwnProperty(itemIndex)) {
			continue;
		}
		if (textgrid.intervalsByXmin[itemIndex]) {
			row = {};
			for (intervalIndex = 0; intervalIndex < textgrid.intervalsByXmin[itemIndex].length; intervalIndex++) {
				interval = textgrid.intervalsByXmin[itemIndex][intervalIndex];
				row.startTime = row.startTime ? row.startTime : interval.xmin;
				row.endTime = row.endTime ? row.endTime : interval.xmax;
				row.utterance = row.utterance ? row.utterance : interval.text.trim();
				row.modality = "spoken";
				row.tier = interval.tierName;
				row.speakers = interval.speaker;
				row.audioFileName = interval.fileName || audioFileName;
				row.CheckedWithConsultant = interval.speaker;
				consultants.push(row.speakers);
				row[interval.tierName] = interval.text;
				header.push(interval.tierName);
			}
			matrix.push(row);
		}
	}
} else {
	for (itemIndex in textgrid.intervalsByXmin) {
		if (!textgrid.intervalsByXmin.hasOwnProperty(itemIndex)) {
			continue;
		}
		if (textgrid.intervalsByXmin[itemIndex]) {
			for (intervalIndex = 0; intervalIndex < textgrid.intervalsByXmin[itemIndex].length; intervalIndex++) {
				row = {};
				interval = textgrid.intervalsByXmin[itemIndex][intervalIndex];
				row.startTime = row.startTime ? row.startTime : interval.xmin;
				row.endTime = row.endTime ? row.endTime : interval.xmax;
				row.utterance = row.utterance ? row.utterance : interval.text.trim();
				row.modality = "spoken";
				row.tier = interval.tierName;
				row.speakers = interval.speaker;
				row.audioFileName = interval.fileName || audioFileName;
				row.CheckedWithConsultant = interval.speaker;
				consultants.push(row.speakers);
				row[interval.tierName] = interval.text;
				header.push(interval.tierName);
				matrix.push(row);
			}
		}
	}
}
