AssemblyAI Audio Transcript
===========================

This covers how to load audio (and video) transcripts as document objects from a file using the [AssemblyAI API](https://www.assemblyai.com/docs/api-reference/transcript).

Usage[​](#usage "Direct link to Usage")
---------------------------------------

First, you'll need to install the official AssemblyAI package:

*   npm
*   Yarn
*   pnpm

    npm install assemblyai

    yarn add assemblyai

    pnpm add assemblyai

To use the loaders you need an [AssemblyAI account](https://www.assemblyai.com/dashboard/signup) and [get your AssemblyAI API key from the dashboard](https://www.assemblyai.com/app/account).

Then, configure the API key as the `ASSEMBLYAI_API_KEY` environment variable or the `apiKey` options parameter.

    import {  AudioTranscriptLoader,  // AudioTranscriptParagraphsLoader,  // AudioTranscriptSentencesLoader} from "langchain/document_loaders/web/assemblyai";// You can also use a local file path and the loader will upload it to AssemblyAI for you.const audioUrl = "https://storage.googleapis.com/aai-docs-samples/espn.m4a";// Use `AudioTranscriptParagraphsLoader` or `AudioTranscriptSentencesLoader` for splitting the transcript into paragraphs or sentencesconst loader = new AudioTranscriptLoader(  {    audio: audioUrl,    // any other parameters as documented here: https://www.assemblyai.com/docs/api-reference/transcript#create-a-transcript  },  {    apiKey: "<ASSEMBLYAI_API_KEY>", // or set the `ASSEMBLYAI_API_KEY` env variable  });const docs = await loader.load();console.dir(docs, { depth: Infinity });

#### API Reference:

*   [AudioTranscriptLoader](https://v02.api.js.langchain.com/classes/langchain_document_loaders_web_assemblyai.AudioTranscriptLoader.html) from `langchain/document_loaders/web/assemblyai`

> **info**
> 
> *   You can use the `AudioTranscriptParagraphsLoader` or `AudioTranscriptSentencesLoader` to split the transcript into paragraphs or sentences.
> *   The `audio` parameter can be a URL, a local file path, a buffer, or a stream.
> *   The `audio` can also be a video file. See the [list of supported file types in the FAQ doc](https://www.assemblyai.com/docs/concepts/faq#:~:text=file%20types%20are%20supported).
> *   If you don't pass in the `apiKey` option, the loader will use the `ASSEMBLYAI_API_KEY` environment variable.
> *   You can add more properties in addition to `audio`. Find the full list of request parameters in the [AssemblyAI API docs](https://www.assemblyai.com/docs/api-reference/transcript#create-a-transcript).

You can also use the `AudioSubtitleLoader` to get `srt` or `vtt` subtitles as a document.

    import { AudioSubtitleLoader } from "langchain/document_loaders/web/assemblyai";// You can also use a local file path and the loader will upload it to AssemblyAI for you.const audioUrl = "https://storage.googleapis.com/aai-docs-samples/espn.m4a";const loader = new AudioSubtitleLoader(  {    audio: audioUrl,    // any other parameters as documented here: https://www.assemblyai.com/docs/api-reference/transcript#create-a-transcript  },  "srt", // srt or vtt  {    apiKey: "<ASSEMBLYAI_API_KEY>", // or set the `ASSEMBLYAI_API_KEY` env variable  });const docs = await loader.load();console.dir(docs, { depth: Infinity });

#### API Reference:

*   [AudioSubtitleLoader](https://v02.api.js.langchain.com/classes/langchain_document_loaders_web_assemblyai.AudioSubtitleLoader.html) from `langchain/document_loaders/web/assemblyai`
