This package is the JavaScript implementation of Deepgram's WebVTT and SRT formatting. Given a transcription, this package can return a valid string to store as WebVTT or SRT caption files.
Works with ANY transcription format.
npm install @deepgram/captions
# - or -
# yarn add @deepgram/captionsimport { webvtt } from "@deepgram/captions";
const result = webvtt(deepgram_transcription_result);import { srt } from "@deepgram/captions";
const result = srt(deepgram_transcription_result);This package has been built to convert any transcription format. You only need to provide a converter class to provide the formatters with the correct data.
A generic converter would look like this:
import { chunkArray, WordBase, IConverter } from "@deepgram/captions";
export class GenericConverter implements IConverter {
constructor(public transcriptionData: any) {}
getLines(lineLength: number = 8): WordBase[][] {
const results = this.transcriptionData;
let content: WordBase[][] = [];
results.paragraphs.forEach((paragraph) => {
if (paragraph.words.length > lineLength) {
content.push(...chunkArray(paragraph.words, lineLength));
} else {
content.push(paragraph.words);
}
});
return content;
}
}It requires that getLines return the following data structure:
// const transcriptionData: WordBase[][] = [
const transcriptionData = [
[
{
word: string;
start: number;
end: number;
punctuated_word: string; // optional
}
]
]Using your converter will look like this:
import { srt } from "@deepgram/captions";
const result = srt(new GenericConverter(transcription_result));import { webvtt, AssemblyAiConverter } from "@deepgram/captions";
const result = webvtt(new AssemblyAiConverter(assembly_result));When transcribing https://dpgr.am/spacewalk.wav, and running it through our library, this is the WebVTT output.
import { webvtt } from "@deepgram/captions";
const result = webvtt(deepgram_transcription_result);
console.log(result);This is the result:
WEBVTT

Yeah. As as much as, it's worth celebrating,
00:00:04.400 --> 00:00:05.779
the first, spacewalk,
00:00:06.319 --> 00:00:07.859
with an all female team,
00:00:08.475 --> 00:00:10.715
I think many of us are looking forward
00:00:10.715 --> 00:00:13.215
to it just being normal and
00:00:13.835 --> 00:00:16.480
I think if it signifies anything, It is
00:00:16.779 --> 00:00:18.700
to honor the the women who came before
00:00:18.700 --> 00:00:21.680
us who, were skilled and qualified,
00:00:22.300 --> 00:00:24.779
and didn't get the same opportunities that we
00:00:24.779 --> 00:00:25.439
have today.
When transcribing https://dpgr.am/spacewalk.wav, and running it through our library, this is the SRT output.
import { srt } from "@deepgram/captions";
const result = srt(deepgram_transcription_result);
console.log(result);This is the result:

00:00:00,080 --> 00:00:03,220

the first, spacewalk, with an all female team,

I think many of us are looking forward
4
00:00:10,715 --> 00:00:14,235
to it just being normal and I think
5
00:00:14,235 --> 00:00:17,340
if it signifies anything, It is to honor
6
00:00:17,340 --> 00:00:19,820
the the women who came before us who,
7
00:00:20,140 --> 00:00:23,580
were skilled and qualified, and didn't get the
8
00:00:23,580 --> 00:00:25,439
same opportunities that we have today.
