This guide will walk you through how to transcribe pre-recorded audio with the Reverie API. We provide two scenarios to try: transcribe a remote file and transcribe a local file.

Before you start, you’ll need to follow the steps in the Get your API Credentials to obtain your API key.

​
Make your first Call

Make your first API Call using the cURL request. Add your own API Credentials where it says <YOUR-APP-ID> & <YOUR-API-KEY> and then run the following example in a terminal or your favorite API client.

​
Step 1 : Upload the Audio File

Upload the Audio File to the API.

​
Request: Transcribing Audio

curl --location --request POST 'https://revapi.reverieinc.com/upload' \
--header 'src_lang: hi' \
--header 'domain: generic' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APPNAME: stt_batch' \
--header 'REV-APP-ID: <YOUR API-ID>' \
--header 'subtitles: true' \
--form 'file=@"<File Path>"'

​
Response: Success

{
    "job_id": "e21f356d-cbf9-4d62-a960-1e9da1805d19",
    "code": "000",
    "message": "Success. Request accepted"
}

In the response, you will receive job_id. Please note it.

​
Step 2 : Get the Status

Send the job_id received in the Step 1 as the query parameter to know the status of the ongoing process of transcription.

​
Request: Get status of the transcription

curl --location --request GET 'https://revapi.reverieinc.com/status?job_id=<job_id>' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APPNAME: stt_batch' \
--header 'REV-APP-ID: <YOUR API-ID>'

​
Response: Success

{
    "job_id": "e21f356d-cbf9-4d62-a960-1e9da1805d19",
    "code": "000",
    "message": "Transcript ready.",
    "status": "completed"
}

In the response, you will receive status = completed and message = Transcript ready once the transcription is complete. Otherwise, you will receive status = applying.

​
Step 3 : Get the Transcript

Once the status = completed in the Step 2, You can use the job_id received in the Step 1 or Step 2 as the query parameter to get the Transcript.

​
Request: Get transcript of the transcription

curl --location --request GET 'https://revapi.reverieinc.com/transcript?job_id=<job_id>' \
--header 'REV-API-KEY: <YOUR API KEY>' \
--header 'REV-APPNAME: stt_batch' \
--header 'REV-APP-ID: <YOUR API-ID>'
