Does Azure Speech to Text only supports WAV file?

I have files in OGG OPUS format from WhatsApp but can not use this Azure service to convert that speech audio into text.
I had to use other cloud for this.

Can Azure Speech to Text accept OGG OPUS; MP3?

I tried NAudio to read or convert the OGG OPUS TO WAV, but it does not work. Also this would increase the file size.

On other cloud, it was just send the file and get the text. Quick and easy. But I am Azure fan, would like to have this on Azure.

    @Tony Thanks for the question. The default audio streaming format is WAV (16 kHz or 8 kHz, 16-bit, and mono PCM). Outside of WAV / PCM, the compressed input formats listed are also supported using GStreamer.
    Here is the doc for supported input formats and samples.

    The below python code is converting any audio files size:
