I used to use Google TTS, but they changed their interface so I couldn't use it anymore ... so here are some other options.
There are several linux packages that convert text to speech:
say converts text to audible speech using the GNUstep speech engine:
sudo apt-get install gnustep-gui-common say "hello"
festival General multi-lingual speech synthesis system:
sudo apt-get install festival echo "hello" | festival --tts
spd-say sends text-to-speech output request to speech-dispatcher:
sudo apt-get install speech-dispatcher spd-say "hello"
espeak is a multi-lingual software speech synthesizer:
sudo apt-get install espeak espeak "hello"
say - macOS
Mac has a builtin program called say which works very nicely:
NAME say - Convert text to audible speech SYNOPSIS say [-v voice] [-r rate] [-o outfile [audio format options] | -n name:port | -a device] [-f file | string ...] DESCRIPTION This tool uses the Speech Synthesis manager to convert input text to audible speech and either play it through the sound output device chosen in System Preferences or save it to an AIFF file.
Unlike say above, you can play with the pitch.
