nanotts call

[zen2]

I have struggle today to use nanotts from exec node in node-red by calling a script with message as parameter.
Looking for a solution I found your issue on nanotts github and your notice on this repository.
I got same error than you: "**error: multiple inputs" while using either option -i or -f with a temporary file with text.
I finally find a solution by not using both options:

#!/bin/bash

DIR="/home/homeassistant/tts/nanotts"
CMD="nanotts -l $DIR/lang -v fr-FR --volume 0.1 -p"
MSG="$@"

echo "$MSG" | "$DIR"/$CMD 2>/dev/null

I call this script wirh exec node in node-red with the message between double quotes.
I hope that can help you for your node-red palette.
I will be using it once you solve this point. ;)
