transcript-model
JSON schema and JavaScript model classes for dealing with time-aligned transcripts of speech.
Usage
Install in your project
$ npm install --save transcript-model
Then
const { Transcript } = require("transcript-model");
// Define some transcript JSON
const json = {
speakers: [
{ name: "Alice" },
{ name: "Bob" }
],
segments: [
{
speaker: 0,
words: [
{ start: 0.05, end: 0.64, text: "Hello" },
{ start: 0.70, end: 1.10, text: "Bob!" }
]
},
{
speaker: 1,
words: [
{ start: 1.53, end: 1.88, text: "Hi" },
{ start: 1.92, end: 2.33, text: "Alice." }
]
}
]
}
// Instantiate a Transcript object
const transcript = Transcript.fromJson(json);
// Do something with it
console.log(
transcript.segments.map(segment => (
transcript.speakers.get(segment.speaker).name
+ ': '
+ segment.words.map(word => word.text).join(' ')
))
.join('\n')
);
// Serialise as JSON
console.log(transcript.toJson());
Try it out on RunKit.
