Linux Text To Speech Comparison: Flite Vs Pico2Wave Vs Festival

Comparison of open-source text to speech software in terms of pleasantness, comprehensibility, and modularity.

Flite in comparison to Festival has:

  • pleasant voices
  • samely comprehensible voices
  • big problems when combination with ffmpeg streaming encoding over bash pipes (This is why I don’t use it for audiobook generation.)
  • designed for embedded devices (see docs )

pico2wave in comparison to Festival has:

  • similarly pleasant voice
  • less comprehensible voice
  • problems when one needs to be piping text into it and resolvable problems when one needs to be piping from it: ln -sf /dev/fd/1 /tmp/stdout.wav; while IFS= read -r line; do pico2wave -w /tmp/stdout.wav "$line"; done | ...
  • designed for embedded devices
