Single-word/sentence assessment usage

Single-word/single-file assessment for a single file (batch) mode. The developer sever/app sends a TCP call to the ELSA server with all information necessary for the assessment to take place. The Elsa server performs the process synchronously and sends a result back, in the the same call when it is ready. To perform an assessment on a word or sentence the developer need to provide:

• word/sentence expected to be found in the audio
• Audio to be analyzed
• API token provided by ELSA

Header Parameters

Authorization: Elsa string required

multipart/form-data

Request Body

Audio data can be processed in 3 different ways:

• audio_file: @<local_audio_file_path> → (note the ‘@’ for multipart upload of a binary file) allows to send a local audio file
• audio_path: <remote_audio_path_url> → points to a URL path to an audio file available online. Make sure the audio file is accessible.
• audio_data: <base64_data_string> → audio data sent as a string, encoded in base64

sentence string required
audio_file binary required

Possible values: Value must match regular expression @<local_audio_file_path>;<remote_audio_path_url> ;<base64_data_string>
