Transcription & Translation Usage

Portkey supports both Transcription and Translation methods for STT models and follows the OpenAI signature where you can send the file (in flac, mp3, mp4, mpeg, mpga, m4a, ogg, wav, or webm formats) as part of the API request. Here’s an example: OpenAI NodeJSOpenAI PythonREST
  • OpenAI NodeJS
  • OpenAI Python
  • Python SDK
  • cURL
import fs from "fs";
import OpenAI from "openai";
import { PORTKEY_GATEWAY_URL, createHeaders } from 'portkey-ai'

const openai = new OpenAI({
  apiKey: "PORTKEY_API_KEY",
  baseURL: PORTKEY_GATEWAY_URL
});

// Transcription

async function transcribe() {
  const transcription = await openai.audio.transcriptions.create({
    file: fs.createReadStream("/path/to/file.mp3"),
    model: "@openai/whisper-1",
  });

  console.log(transcription.text);
}
transcribe();

// Translation

async function translate() {
    const translation = await openai.audio.translations.create({
        file: fs.createReadStream("/path/to/file.mp3"),
        model: "@openai/whisper-1",
    });
    console.log(translation.text);
}
translate();
On completion, the request will get logged in the logs UI where you can see trasncribed or translated text, along with the cost and latency incurred.
