Slow bash script

Question

I use a bash script to translate words from other languages into Portuguese. It always worked very well, but from a few days to here became extremely slow, to the point that I could not use it.
some people informed me that the problem could be in the "wget". I did some tests replacing "wget" with "Axel" or "aria2c" and the speed returned to normal, but using these two commands I cannot get the translation.

The original code is this one:

#!/usr/bin/env bash
text="$(xsel -o)"
translate="$(wget -U "Mozilla/5.0" -qO - "http://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=pt&dt=t&q=$(echo $text | sed "s/[\"'<>]//g")" | sed "s/,,,0]],,.*//g" | awk -F'"' '{print $2}')"
echo -e "Original text:" "$text"'\n' > /tmp/notitrans
echo "Translation:" "$translate" >> /tmp/notitrans
zenity --text-info --title="Translation" --filename=/tmp/notitrans

Line 3 of this code, replacing "wget" with "Axel" is:

translate="$(axel -n 4 "http://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=pt&dt=t&q=$(echo $text | sed "s/[\"'<>]//g")" | sed "s/,,,0]],,.*//g" | awk -F'"' '{print $2}')"

And replacing "wget" with "aria2c" is:

translate="$(aria2c "http://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=pt&dt=t&q=$(echo $text | sed "s/[\"'<>]//g")" | sed "s/,,,0]],,.*//g" | awk -F'"' '{print $2}')"

Maybe I don’t know how to set the options for Axel and Aria2c. For me it doesn’t matter if any of them, I need the code to work again. Would anyone know to steer me in that direction?

It seems unlikely that the delay is due to wget. (but this is not the issue)

Probably the problem with the tested examples has to do with the lack of definition User-agent (the -U "Mozilla/5.0" of wget) -- which causes googleapis not to accept the request.

Suggestion to use the curl.

$ gapi="http://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=pt&dt=t"
$ curl -A "Mozilla/5.0" $gapi -d 'q=le fromage est trés bon'
[[["o queijo é muito bom","le fromage est trés bon",null,null,3.....["fr"]]]

Processing the web-service response (respostaJSON[0][0][0]):

$ curl -A "Mozilla/5.0" $gapi -d 'q=le fromage est trés bon'| jq .[0][0][0]
"o queijo é muito bom"
