Asynchronous Speech-To-Text API Documentation

Text Analysis

Rev.ai provides quality speech-text recognition via a RESTful API. All public methods and objects are documented here for developer reference. For a real-time speech to text solution, use Rev.ai's [Streaming API](/docs/streaming). # Base Endpoint The base url for this version of the API is > `https://api.rev.ai/speechtotext/v1` All endpoints described in this documentation are relative to this base url. # Quick Start Follow the [getting started checklist](https://www.rev.ai/getting_started) ## Get your Access Token You can generate your [access token](#section/Authentication/Access-Token) on the [settings page](https://www.rev.ai/access_token) of your account. This access token only needs to be generated once and never expires. You can re-generate your token, however this will invalidate the previous token. ## Submit a File To submit an audio file for transcription to Rev.ai: ``` curl -X POST "https://api.rev.ai/speechtotext/v1/jobs" -H "Authorization: Bearer $REV_ACCESS_TOKEN" -H "Content-Type: application/json" -d "{\"media_url\":\"https://www.rev.ai/FTC_Sample_1.mp3\",\"metadata\":\"This is a sample submit jobs option\"}" ``` You’ll receive a response like this: ~~~ { "id": "Umx5c6F7pH7r", "created_on": "2018-09-15T05:14:38.13", "name": "sample.mp3", "metadata": "This is a sample submit jobs option for multipart", "status": "in_progress" } ~~~ The `id` (in this case `Umx5c6F7pH7r`) will allow you to retrieve your transcript. ## Get Your Transcript Once a transcription job's `status` becomes `transcribed`, you can retrieve the transcript in JSON format by running: ``` curl -X GET "https://api.rev.ai/speechtotext/v1/jobs/{id}/transcript" -H "Authorization: Bearer $REV_ACCESS_TOKEN" -H "Accept: application/vnd.rev.transcript.v1.0+json" ``` Alternatively you can get the plain text version by running: ``` curl -X GET "https://api.rev.ai/speechtotext/v1/jobs/{id}/transcript" -H "Authorization: Bearer $REV_ACCESS_TOKEN" -H "Accept: text/plain" ``` You can poll for the `status` of your job by querying for the job periodically: ``` curl -X GET https://api.rev.ai/speechtotext/v1/jobs/{id} -H "Authorization: Bearer $REV_ACCESS_TOKEN" ``` **Note:** Polling is NOT recommended in a production server. Rather, use [webhooks](#section/Webhooks) to asynchronously receive notifications once the transcription job completes If you have any further questions, contact us at <[email protected]> # Submitting Files Two `POST` request formats can be used to submit a file: `application/json` or `multipart/form-data`. ## JSON This is the preferred method of file submission. Uses the `media_url` property to provide a direct download URL to the Rev.ai server. This method supports the use of pre-signed URLs. Links to videos hosted on platforms like Youtube are not valid because they are not direct download links. **Important note on presigned URLs:** Signed URLs usually have an expiration time which is configurable. To ensure the Rev.ai server can access the link, make sure the expiration time is set to 2 hours or more. In the event you plan on resending the same file, make sure to generate a new presigned URL. ## FormData Used to send a local file to the Rev.ai server. This allows the customer to send the file directly from the host machine. Certain limits apply to this format, see the [Async API Limits section](#section/Async-API-Limits) for more detals. # Turnaround Time and Chunking Often, especially for shorter files, your transcript will be ready in 5 minutes or less. It generally takes no longer than 15 minutes to return longer audios. If you require faster turn around time please contact <[email protected]> Chunking is the act of breaking audio files into smaller segments. Rev.ai uses this method to decrease turnaround time of audios greater than 3 minutes in length. # Webhooks If the optional `callback_url` is provided, the API will make an HTTP POST request to the `callback_url` with the following request body when the job either completes successfull

SEDRA IV API

Text Analysis

The SEDRA API is documented in **OpenAPI format** and uses [ReDoc](https://github.com/Rebilly/ReDoc) for documentation. # Introduction This document describes the JSON API for the Syriac Electronic Data Research Archive (SEDRA). The SEDRA project is a linguistic and literary database of Syriac language and literature focusing on providing electronic access to the corpus of Syriac lexicons with linguistic information added to each entry in those lexicons. The API is a mechanism to provide the linguistic information stored in SEDRA to a broader audience. Additionally there is a XML API for Syriac words which conforms to a prototype Semitic Languages schema which can be found in the XSD file https://sedra.bethmardutho.org/api/semiticLanguages.xsd. # Cross-Origin Resource Sharing This API features Cross-Origin Resource Sharing (CORS) implemented in compliance with the [W3C spec](https://www.w3.org/TR/cors/) and allows cross-domain communication from the browser. All responses have a wildcard same-origin which makes them completely public and accessible to everyone, including any code on any site. # Samples Explaining how to lookup words in the SEDRA API is complex and would clutter the API description. For that reason we have chosen to give the explanation of how to lookup words in its own section. SEDRA can lookup words by the SEDRA word Id. However, it will often be the case that the consumer of information provided by the SEDRA API does not know the SEDRA word Id. It is for that reason that the SEDRA API provides a method to lookup words by the Syriac text. But that process is complicated by the nature of Syriac writing. So the SEDRA API will lookup words for consonantal, partially vocalized, and fully vocalized Syriac text. Using the word Id will provide the most accurate results as the exact word will be returned. Fully vocalized text will provide the next most accurate result. The least accurate results will be returned by partially vocalized and consonantal Syriac words in that order. Following are some samples to help understand how this works. 1. By Word Id [30862](https://sedra.bethmardutho.org/api/word/30862.json) 2. By fully vocalized Syriac word [ܐܰܒܳܪܳܐ](https://sedra.bethmardutho.org/api/word/ܐܰܒܳܪܳܐ.json) 3. By partially vocalized Syriac word [ܐܶܒܪܐ](https://sedra.bethmardutho.org/api/word/ܐܶܒܪܐ.json) 4. By consonantal Syriac word [ܐܒܪܐ](https://sedra.bethmardutho.org/api/word/ܐܒܪܐ.json).
