Spoken translations in Emacs

Finally, continuing our experiments with computer speech for fun, let us try a translation of text to another language that is then spoken. Here is a free translator that has the courtesy to reply with json with the translated text in it. http://mymemory.translated.net/api/get?q=Hello%20World!&langpair=en|de I had to download a German voice called Anna, then get some translated text.

As with previous posts, there is a video: https://www.youtube.com/watch?v=8CBKnahE0ak . I am trying ScreenFlow for these (instead of Camtasia), and I still have not quite mastered the aspect ratio, so the videos still look a little odd.

As a reminder, we have this easy way to speak text in applescript. If you are on Linux, check out Festival and on windows you may find some inspiration here .

(do-applescript "say \"Hello. My name is John. I am glad to meet you.\"")

You can retrieve json data of the translated text, and then we can use it in our word-speak function we previously developed. Here is an example in in German.

(let* ((words-voice "Anna")
       (text "Hello. My name is John. I am glad to meet you.")
       (url (format "http://mymemory.translated.net/api/get?q=%s!&langpair=en|de"
                    text))
       (json (with-current-buffer
                 (url-retrieve-synchronously url)
               (json-read-from-string
                (buffer-substring url-http-end-of-headers (point-max)))))
       (translated-text (cdr (assoc 'translatedText (cdr (assoc 'responseData json))))))
  (words-speak translated-text)
  translated-text)

"Hallo. Mein Name ist John. Ich freue mich, Sie kennen zu lernen.!"

How about Chinese? Again, I downloaded a Chinese voice called "Ting-Ting".

(let* ((words-voice "Ting-Ting")
       (text "Hello. My name is John. I am glad to meet you.")
       (url (format "http://mymemory.translated.net/api/get?q=%s!&langpair=en|zh"
                    text))
       (json (with-current-buffer
                 (url-retrieve-synchronously url)
               (json-read-from-string
                (buffer-substring url-http-end-of-headers (point-max)))))
       (translated-text (cdr (assoc 'translatedText (cdr (assoc 'responseData json))))))
  (words-speak translated-text)
  translated-text)

"你好。我的名字是约翰。我很高兴见到你。!"

So, can any Chinese readers and listeners confirm if the text translates correctly, and if Ting-Ting said it correctly? Hopefully it is good enough to make some sense and be useful!
