Piper traceback

[mike99mac]

Hi, thanks for piper and all you've done for voice.

I'm trying to bake piper into my fork of Ken Smith's Minimy. I'm testing it by sending two paragraphs but always get a traceback in the same place - after playing about 7 seconds.

Any help will be appreciated.

$ cat twop | piper -m /home/pi/minimy/voice/en_US-lessac-medium.onnx | aplay

Use the --output-raw argument to have Piper output raw audio. You will also need to adjust aplay since it expects WAV input:

cat twop | \
  piper -m /home/pi/minimy/voice/en_US-lessac-medium.onnx --output-raw | \
  aplay -r 22050 -f S16_LE -t raw -
