问题 I'm using pocketsphinx with raspberry pi for home automation. I've written a simple JSGF grammar file with the supported commands. Now, I want to use an activation phrase such as "hey computer" prior to the commands, to avoid false detections and only perform speech recognition once the activation phrase has been spoken. If I'm not getting this wrong, pocketsphinx supports two modes for speech recognition: keyword spotting mode, and language model / JSGF grammar mode. In pocketsphinx FAQ when

问题 I have found ways to make pocketsphinx activate using multiple keywords, but I want to run diffrent commands depending on which keyword was said.

问题 I am using the default dictionary that comes with the pocketsphinx demo which is good for my purposes. When a user enters a phrase, the app starts a keyphrase listening but if the word is not found in the dictionary the app crashes. The app crashes onError() within a service. How is the error handling done? is there any way I can catch the error? Overall I would just like the service to call stopSelf() when an error happens so the main activity won't crash as well. Errors: ERROR: "kws_search

问题 I want to start a new activity that recognizes speech from the beginning and could read incoming message right after the activity started. This code is the code that merged from default. It runs well in default condition. But I want to remove the button as the trigger and use voice instead to trigger further action in SMSReaderMain.java .

问题 I am currently trying to make my java code (using eclipse) perform some function if a certain thing is said. I am using the Sphinx4 libraries and this is what I currently have: What I would like it to do is at the line where it says: IF (TRUE) someFunction(); is to run the function if my speech is Hello Computer, Hello Jarvis, Good Morning Computer, or Good Morning Jarvis. Or in other words, run the function if the speech matches the "public < greet >" line of code in the .gram file. Even
