Comment(by jonsd):
Is this still a problem?
My theory is that
espeak --stdout "hello" | aplay
May not work because it produces WAV output, but with length = 0 in the
WAV header. This is because when it starts to produce the speech sound, it
doesn't know how long it will be. espeak -w is OK because it writes to a
file, and it can rewind and fill in the length information in the header
after it has finished writing the speech sound data. But espeak --stdout
can't do that.
So whether espeak --stdout is useful depends on whether the program which
uses its output (aplay) can cope with "length = 0".
Is that the problem?
Alternatives are to write the speech to a file and then play it:
espeak -f temp.wav "hello"
Or use the espeak API to generate buffers of speech which your application
can then play under its control.
Or use espeak with its portaudio interface to play the sound.
