Example of invoking Voicegain API from node.js (/asr/transcribe) – Voicegain

Synchronous transcribe with audio retrieved from a URL

Below is an example node.js code that invokes synchronous POST /asr/transcribe Web API. It gets audio from the provided URL, transcribes it, and returns the transcription result.

USER_GENERATED_JWT_TOKEN should be replaced with a JWT token obtained as described here https://support.voicegain.ai/hc/en-us/articles/360028023691-JWT-Authentication (Note: the "Web API" setting shown in the screenshot is now called "API Security")

const https = require("https");

const jwt_Token = "USER_GENERATED_JWT_TOKEN"
const bearer = "Bearer" + " " + jwt_Token;

const post_data = JSON.stringify({
  audio: {
    source: {
      fromUrl: {
        url:
          "https://f002.backblazeb2.com/file/voicegain-cdn/499632__iceofdoom__hello-is-anyone-out-there-curious-male-16kHz-mono.wav",
      },
    },
  },
});

const options = {
  hostname: "api.voicegain.ai",
  path: "/v1/asr/transcribe",
  method: "POST",
  headers: {
    Authorization: bearer,
    "Content-Type": "application/json",
    "Content-Length": post_data.length,
    Accept: "application/json",
  },
};

const req = https.request(options, (res) => {
  console.log("statusCode:", res.statusCode);
  console.log("headers:", res.headers);

  res.on("data", (d) => {
    process.stdout.write(d);
  });
});

req.on("error", (err) => {
  console.log("Error: " + err.message);
});

req.write(post_data);
req.end();
