How to use sox to convert mp3 file from stdin?

I have a situation where I get a mp3 audio output in the stdout, and I'd like to save it directly in a wav file.

Example:

I could do that:

gtts-cli "Hello World" -o out.mp3 && sox out.mp3 out.wav`

But I'd like something as:

gtts-cli "Hello World" | sox -p out.wav

Now this command raise the error:

sox FAIL formats: can't open input '-': can't find sox file format identifier.

I have installed the library libsox-fmt-mp3. I also get the same error if I try:

gtts-cli "Hello World" | sox -p -t mp3 out.wav

Thanks,

Something like | sox -t mp3 - out.wav should work.
