@pietrop/serialize-stt-words v1.0.0

serialize-stt-words

A module to serialize and deserialize words from STT in dpe format into arrays of each attribute.

eg with euristics if mock8hours.json is 8 hours and 9.6MB

This is the breakdown of file size for each attribute saved seperately.

 58K paragraphEndTimes.json
 59K paragraphStartTimes.json
 93K speakersLit.json
637K textList.json
637K wordEndTimes.json
653K wordStartTimes.json

Well within the 1MB firebase document limit.

Setup

git clone git@github.com:pietrop/serialize-stt-words.git

cd serialize-stt-words

npm install

Usage

{
    "words": [
        {
            "text": "Hello",
            "start": 0,
            "end": 0.88
        },
        ....
    ],
  "paragraphs": [
        {
            "speaker": "SPEAKER_B",
            "start": 0,
            "end": 1.24
        },
    ...
   ]
}

Returns arrays of

npm install @pietrop/serialize-stt-words

const { serializeTranscript } = require('@pietrop/serialize-stt-words');
const { wordStartTimes, wordEndTimes, textList, paragraphStartTimes, paragraphEndTimes, speakersLit } = serializeTranscript(transcript);

{
    "wordStartTimes": [
        0,
        0.9,
        1.13,
        ...
    ],
  "wordEndTimes": [
        0.88,
        1.12,
        ...
    ],
    "textList": [
        "Media",
        "will",
        ...
    ],
    "paragraphStartTimes": [
        0,
        1.25,
        ...
    ],
    "paragraphEndTimes": [
        1.24,
        4,
        ...
    ],
    "speakersLit": [
        "SPEAKER_B",
        "SPEAKER_A",
        ...
    ]
}

The idea being that you could save each separate in a db and recombine later.

const { deserializeTranscript } = require('@pietrop/serialize-stt-words');
const desRes = deserializeTranscript({ wordStartTimes, wordEndTimes, textList, paragraphStartTimes, paragraphEndTimes, speakersLit });
