Vista Speech Recognition in Delphi

阅读更多关于 Vista Speech Recognition in Delphi

I would like to be able to dictate into my Delphi application using Microsoft Vista's speech recognition. However when attempting to dictate into a TMemo, it simply does not work. I noticed that Firefox 3.0 has the same issue and after they contacted Microsoft about the problem, they told them that they need to implement the Text Services Framework for their application. I am wondering if there is any way to implement this in Delphi so that I can dictate into a TMemo or a TRichEdit. Searching Google for a solution didn't return any relevant results.

Is there any way to send audio file to the speech-to-text recognition

阅读更多关于 Is there any way to send audio file to the speech-to-text recognition

I want the Android speech recognition system analysing audio file and not the default incoming voice from microphone. Is there any way to do that ? Thank you. I suppose it works in a similar way to the chrome api - http://mikepultz.com/2011/03/accessing-google-speech-api-chrome-11/ As he has mentioned you can convert the microphone file into a .flac file and send it to the speech api, and you will get the same result. So you can use SOX and convert it yourself. Hope it helps. Dias cmusphinx.sourceforge.net/wiki/tutorialandroid Just found that link sounds like someone has created a android
