[Feature]: Support Azure OpenAI in Text-To-Speech

[lurebat]

The Feature

Great work on #3928 , but currently it only supports openai and compatible endpoints, and not azure's API.

Motivation, pitch

I use litellm's proxy to use azure's openapi with plenty of compatible software, but currently there is no workaround for text-to-speech.

The api is very similar obviously, it just needs the minor adjusments all azure apis have

Twitter / LinkedIn details

No response

hey @lurebat curious how do you plan on using litellm proxy w/ azure tts?

if there's a specific software / e2e flow you had in mind, that would help me test it out

also is this the azure tts - https://learn.microsoft.com/en-us/azure/ai-services/speech-service/rest-text-to-speech?tabs=streaming#request-body-1?

it seems to require some sort of separate query language (SSML)

Hey, I want to use it with https://github.com/danny-avila/LibreChat and homeassistant.

What you linked is another service and not what I'm referring to, I want to use the openai speech api: https://learn.microsoft.com/en-us/azure/ai-services/openai/text-to-speech-quickstart?tabs=command-line#rest-api

Got it, thanks for clarifying

Likewise, I want to use tts-1-hd on Azure OpenAI through LiteLLM for LibreChat.

Can we do a 10min call this week? Would love to learn how you're using litellm, so we can improve
