Read user input inside a loop

I am having a bash script which is something like following,

cat filename | while read line
do
    read input;
    echo $input;
done

but this is clearly not giving me the right output as when I do read in the while loop it tries to read from the file filename because of the possible I/O redirection.

Any other way of doing the same?

bash

I have found this parameter -u with read.

"-u 1" means "read from stdout"

while read -r newline; do
    ((i++))
    read -u 1 -p "Doing $i""th file, called $newline. Write your answer and press Enter!"
    echo "Processing $newline with $REPLY" # united input from two different read commands.
done <<< $(ls)
