Cannot inject custom http client for text to audio and audio to text services using open ai services

[giannik]

Semantic kernel allows for open AI chat completion to provide your own HTTP client in the constructor while building the kernel . This is very useful for multi tenant scenarios to better organize http client management.
But I noticed that for open ai audio to text and open AI text to audio the constructor does not allow this implementation for custom HTTP client. Why is this?

  //this works 
Kernel.CreateBuilder()
    .AddOpenAIChatCompletion("gpt-4-vision-preview", decryptedOpenAiKey , httpclient )   //this works 




//but for these services i cannot inject own http client (only openaiclient is allowed.) . i wish to follow same pattern as chat   completion
builder.Services.AddOpenAIAudioToText(
    modelId: AudioToTextModel,
    apiKey: decryptedOpenAiKey, ???
    );

builder.Services.AddOpenAITextToAudio(
    modelId: TextToAudioModel,
    apiKey: decryptedOpenAiKey, ???
   );

@giannik - thanks for asking. @RogerBarret0 - can you provide some guidance on why we did this?

When using builder.Services you are targeting ServiceCollection which is a Dependency Injection focused collection.

To achieve your goal, you need to have a HttpClient added to your services DI Container so it can be injected automatically in the Connector Services.

AddOpenAITextToAudio code.

semantic-kernel/dotnet/src/Connectors/Connectors.OpenAI/Extensions/OpenAIServiceCollectionExtensions.cs

Line 179 in e23d636

HttpClientProvider.GetHttpClient(serviceProvider),

HttpClientProvider.GetHttpClient

semantic-kernel/dotnet/src/InternalUtilities/src/Http/HttpClientProvider.cs

Line 39 in e23d636

public static HttpClient GetHttpClient(IServiceProvider? serviceProvider = null) => GetHttpClient(serviceProvider?.GetService<HttpClient>());

@RogerBarret0 thank you.
Does'nt this mean that from the service collection Semantic kernel will pick the first available HttpClient available ?

What if i have injected more httpclients for other purposes or if the service collection comes from my main app and not specific to semantic kernel.

Maybe if somehow i could specify with a key that this http client is specific for semantic kernel only ?
