piper -- neural TTS (higher quality)

For higher quality offline TTS, consider piper:

echo "Hello world" | piper --model en_US-lessac-medium --output_file output.wav
aplay output.wav

Command blocks until speech completes (espeak, spd-say). On headless systems, audio output requires ALSA or PulseAudio.
