How can I use pyaudio for Streaming instead of aplay

[JahanHH]

Unfortunately i have the problem that i can't use 'aplay' under windows because it can only be installed via linux (maybe i'm wrong).
But I can use pyaudio under windows.
Is it possible to use pyaudio instead of aplay for streaming?
If so, can someone give me an example of what really works?

I'm sure there's a way to use pyaudio but I haven't got that one down yet, but I did find out how to do it in Windows with VLC or ffplay (usually comes with ffmpeg). It took me FAR too long to figure this out, but I eventually got it. Make sure you put Piper and VLC (or ffplay) in your PATH and then you can do the following commands in a terminal.

This will synthesize the audio and stream the playback with VLC without making a file:

echo "This is piper." | piper -m "C:\your\voice\path\voice.onnx" --output-raw | vlc -I dummy --demux=rawaud --rawaud-samplerate 22050 --rawaud-channels=1 --rawaud-fourcc=s16l - vlc://quit

This will generate a file and then play it with VLC:

echo "This is piper." | piper -m "C:\your\voice\path\voice.onnx" -f "C:\your\output\path\filename.wav"
vlc -I dummy "C:\your\output\path\filename.wav" vlc://quit

Alternatively you can use ffplay to stream:

echo "This is piper." | piper -m "C:\your\voice\path\voice.onnx" --output-raw | ffplay -f s16le -ar 22050 -ac 1 -nodisp -autoexit -
