Effortlessly Transcribe Audio in .NET with OpenAI's Transcriptions Feature

Introduction

The ever-evolving landscape of artificial intelligence offers numerous opportunities for developers to simplify and enrich their applications. The ConnectingApps.Refit.OpenAI NuGet package continues to rise to the occasion by introducing support for audio transcriptions. This capability allows developers to transcribe audio content and retrieve the corresponding text, even when it's not in English. In this article, we'll delve into how to effortlessly incorporate this feature into your .NET applications.

Background

OpenAI's API has been a game-changer in the realm of artificial intelligence and machine learning. The ability to seamlessly interface with OpenAI's services can offer a significant edge for .NET applications. Previously, I discussed the introduction of the ConnectingApps.Refit.OpenAI NuGet package and its audio translations feature. The newly added audio transcription functionality further elevates its utility.

Using the Code

Implementing the audio transcription feature is straightforward:

1. Ensure the ConnectingApps.Refit.OpenAI NuGet package is installed in your project.
2. Retrieve your OpenAI API key.
3. Transcribe the audio file using the provided C# code snippet.

Below is a demonstration of the audio transcription process in C#:

using ConnectingApps.Refit.OpenAI;
using ConnectingApps.Refit.OpenAI.Transcriptions;
using Refit;

var apiKey = Environment.GetEnvironmentVariable("OPENAI_KEY");
var authorizationHeader = $"Bearer {apiKey}";
await using (var recording = new FileStream("HalloWereld.mp3", 
             FileMode.Open, FileAccess.Read))
{
    var openAiApi = RestService.For<itranscription>
    ("https://api.openai.com", OpenAiRefitSettings.RefitSettings);
    var streamPart = new StreamPart(recording, "HalloWereld.mp3");
    var response = await openAiApi.GetAudioTranscription
                   (authorizationHeader, streamPart, "whisper-1");
    Console.WriteLine($"Returned response status code {response.StatusCode}");
    Console.WriteLine($"Actual text {response.Content!.Text}");
} 

Further examples and insights can be found in the package's GitHub repository.
