playing with google text to speach on the Rp4.
scripts I found use mplayer... big piece of code
had a go with wget, resulted in script gst7


#!/bin/bash

# Usage:
# To speak a line of text:           echo "any text" | ./gst7
# To record a line of text as mp3:   echo "any text" | ./gst7 filename.mp3

read user_reply

if [ "$1" == "" ]
then
        wget  --user-agent seamonkey  --no-check-certificate  -O /dev/stdout 
"http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&q=$user_reply&
tl=en" | mpg123 -
else
        wget  --user-agent seamonkey  --no-check-certificate  -O $1 
"http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&q=$user_reply&
tl=en"
fi




OK, but what if I want to speak and record a complete text?
script test1


#!/bin/bash

# Usage:
# ./test1 songtext.txt


# define language of text file, uncomment as required
# GERMAM=
#languahe=de

# ENGLISH
language=en

# FRENCH
#language=fr

# DUTCH
#language=nl


input="$1"

# delete any old index file
rm mp3_list.txt

let i=0
while IFS= read -r line
do
        # show where we are
        echo "$line"

        # one line of text to one mp3 file
        wget  --user-agent seamonkey  --no-check-certificate  -O t$i.mp3 
"http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&q=$line&tl=$la
nguage"

        # generate list of mp3 files one per line
        echo "file 't$i.mp3'" >> mp3_list.txt

        let i=i+1

        # pause between lines, leave this out if you want speed
        sleep 1
done < "$input"




# to playback all generated mp3 files in sequence:
# let i=0 ; while [ 1 ] ; do mpg123 t$i.mp3 ; let i=i+1; sleep 1; done


# to combine mp3 files for playback
# ffmpeg  -f concat  -safe 0  -i mp3_list.txt  -c copy  -y  output.mp3


# to play everything
# mpg123 output.mp3


Could do a whole book that way.
