Single-word/sentence assessment usage - Upload via File

Single-word/single-file assessment for a single file (batch) mode. The developer’s server/app sends a TCP call to the ELSA server with all the necessary information for the assessment. The ELSA server processes the request synchronously and returns the result in the same call once it’s ready.

To perform an assessment on a word or sentence, the developer must provide:

•   The word/sentence expected to be found in the audio
•   The audio file to be analyzed (uploaded as a binary file)
•   The API token provided by ELSA

Header Parameters

Authorization: Elsa string required

multipart/form-data

- audio_file: @<local_audio_file_path> (Note the ‘@’ for multipart upload of a binary file)

This method allows the developer to upload a local audio file for processing.
