How yo stream mic data to web using UnityWebRequest?

Hi. I want to stream mic input data from Unity to wit.ia web server.

According to Unity side, they say: "It also supports high-demand features such as chunked HTTP requests, streaming POST/PUT operations, and full control over HTTP headers and verbs." https://docs.unity3d.com/Manual/UnityWebRequest.html

And in wit.ia page docs they say: "Streaming audio We accept chunked data, which is a good way to reduce latency. In addition to the Content-type header, you must set a Transfer-encoding header to chunked Audio stream shouldn’t exceed 10s of audio time." https://wit.ai/docs/http/20160526#streaming-audio

Here is more details in the wit.ia side: Definition

POST https://api.wit.ai/speech Example request

$ curl -XPOST 'https://api.wit.ai/speech?v=20160526' \ -i -L \ -H "Authorization: Bearer $TOKEN" \ -H "Content-Type: audio/wav" \ --data-binary "@sample.wav"

I dont know how to handle this. Please, keep in mind that im asking for STREAMING. I already know how to do this without streaming (just sending a recorder wav file from disk).

Any ideas will be appreciated!
