Installarlo:
apt install festival
Aggiungere voci
apt install festvox-italp16kapt

Decidere quale voce ha priorità, nel file: /usr/share/festival/voices.scm
POi lo script è:
#!/bin/bash
#This script counts.
#if crash remember there are 86400 sec in a day.
#if crash- if more than a billion
# create a variable to represent the filename
COUNTER_FILE=”counter.txt”
while [ true ]; do
count=`cat $COUNTER_FILE`
echo $count | festival –tts –language italiian
((count++))
