What happened to Cantonese Speech under Bing?
Cantonese speech no longer available under Bing (and possibly elsewhere). For a while Cantonese speech was available, then it was curiously available under Chinese (traditional). Now it is not available under either Chinese (traditional) or Cantonese. What changed?
Cantonese (Traditional) still works on the Bing Translator app on a Windows machine (not the web version). Microsoft still needs to fix their web version though.
I saw the same thing happen last month. You should contact the Translator team about this. Last time I contacted them, they emailed me back fairly quickly about my concern.
