ESpeak can generate text-to-speech (TTS) audio files. These can be useful for many reasons, such as creating your own Turing (Captcha) tests that are capable of speaking its challenge. This article will cover how to install eSpeak and create a simple TTS audio file in
.wav format on CentOS 7.
Log in as the
root user and run the following command to install eSpeak.
# yum install espeak -y
Test eSpeak by asking it to sound out the letters
y j w c t j while writing the output as a
.wav file named
espeak-talk.wav in the
/tmp/ directory. Next, we tell it we want a word gap of 60, the pause between words. We also tell it we want a pitch of 70 and a readout speed of 100.
# espeak "y j w c t j" -w /tmp/espeak-talk.wav -g 60 -p 70 -s 100 -v en-uk
You will now have a file named
espeak-talk.wav located in
