Text to Speech on Ubuntu in Portuguese
We can read PDF files using Text to Speech on Linux with Okular. For this we need to install Speech Dispatcher and RHVoice. Let’s start installing some packages:
# Speech Dispatcher
sudo apt install speech-dispatcher
sudo apt install speech-dispatcher-espeak-ng
sudo apt install python3-speechd
# List voices in portuguese (low quality)
spd-say -L | grep pt-BR | less
# Speak on terminal
spd-say -l "pt-BR" "Sejam todos bem vindo."
spd-say -y "Portuguese (Brazil)+Linda" "Sejam todos bem vindo."
# Configure defaults values
spd-conf
# RHVoice
sudo apt install rhvoice
sudo apt install rhvoice-brazilian-portuguese
sudo apt install speech-dispatcher-rhvoice
# Remove local default values (need reboot)
rm -rf /home/$USER/.config/speech-dispatcher
# List all voices in RHVoice module (high quality) - Remove default values before
spd-say -o rhvoice -L
# Speak on terminal
echo "Sejam bem-vindos!" | RHVoice-test -p "Letícia-F123"
spd-say -o rhvoice -y "Letícia-F123" "Sejam todos bem vindos!"
spd-say -o rhvoice -l pt "Sejam todos bem vindos!"
# Set global confs
# yes -> system -> espeak-ng -> pt-BR -> pulse -> 0 -> 0 -> 0 -> yes -> yes -> yes
sudo spd-conf
Now it’s need to open the file /etc/speech-dispatcher/speechd.conf or ~/.config/speech-dispatcher/speechd.conf and replace this line #DefaultModule espeak-ng with DefaultModule rhvoice. After that we will restart service:
# Restart service
sudo systemctl restart speech-dispatcher.service
sudo reboot
# Speak on terminal
spd-say "Sejam todos bem vindos!"
Now we can install Okular and configure TTS to speak in portuguese.
