Generates a streamed audio file from a text string.

From the user's perspective, this is a standard request. In the response, we include specific headers: 'Transfer-Encoding' is set to 'chunked' to enable streaming, 'Connection' is set to 'keep-alive' to maintain the connection, and 'Content-Type' is set to 'audio/wav' to indicate the media type. These headers allow the client to stream audio data from the server in real time. Important Note: after collecting the chunks, you need to add the wav header manually to the data. If you wish to get a wav header, please use the Generate TTS File Data API.
