You probably now that Stephen Hawking (never got a Nobel Price) was on BigBang A LOT.

And he writes to speech synthesis and eye-tracker.

And he is giving hilarious funny interviews with this thing DECtalk DTC01…

While also saying that AI could go wrong. If AI becomes self-improving – it could outsmart us all.

also it takes some time to get used to… but then you probably get 90% of the text it reads, like this NASA news article about water and lake on mars in English:

or this science article about a lake on mars in German:

here it is:

Oh fuck – it is running Windows 7. I hate the autocomplete on my android phone. it sucks. Well whatever.

so what you will need to output your own text to speech?

not much.

#apt based
apt install xsel espeak festival

#rpm based
yum install xsel espeak festival

xsel takes text from your clipboard and puts it into a bash variable that can then be passed to espeak (src) to speak it.

you can test it like this:

# use english and low pitch voice
espeak -ven-us -p0 "hello world";

# use german and low pitch voice
espeak -vde -p0 "hallo welt";

# you can output to file.wav
espeak -ven-us -p0 "hello world" -w hello_world.wav

here comes a little espeak demo:

it almost sounds like Hawking 🙂

use it to read the clipboard:

# create a new script
touch /bin/talk.sh
chmod +x /bin/talk.sh
vim /bin/talk.sh
# fill with:
#!/bin/bash

# also toutput text to screen
xsel;
text=$(xsel);

if [[ $1 = "de" ]]
then
	espeak -vde -p30 "$text";
else
	xsel | festival --tts --pipe
fi

now you can mark any text on your webbrowser (under mate + lightdm that is enough to get it into clipboard) but you might need to r-click it -> copy or middle-mouse button.

then go to terminal and just type talk.sh (for english) or talk.sh de (for german) and it should display and read the clipboard text.

while espeak can imitate a lot of languages „by default“, for festival you will need tts files, i could not find any except for english.

… espeak does not seem to be able to speak chinese or japanese.
