Speech Recognition for short audio files (sync)

1. Introduction

A speech recognition API that converts user-supplied short speech data (less than 30 seconds) into text. This API operates in a synchronous manner, which allows the development of applications or the establishment of an automatic speech-to-text conversion service using text obtained from speech data.

WARNING

⚠ Songs or audio with loud background music are not supported.

2. Example

Below is an example of how to use the API. In this example, a voice file called 'sample.wav' is sent to the API, which responds by converting the voice into text.

POST

curl 'https://apis.daglo.ai/stt/v1/sync/transcripts>' \
  --header 'Authorization: Bearer <API_TOKEN>' \
  --form 'file=@"sample.wav"'

{
    "rid": "12345678-abcd-efgh-1234-abcdefghijkl",
    "sttResult": {
        "transcript": "Hello, I'm Action Power. See the art of action power, the leader in speech recognition."
    }
}
