When I use google voice search, I can say "Send Text" and google will launch my SMS program.
I can say "Listen to" and google will start my default music app.
Is it possible for my app to register it's own "special phrase" such as: "MyApp DoSomething" and then have google launch MyApp with the "DoSomething" as a type of parameter I can capture and do something with?
To be a little bit more clear - I'm aware that the user can launch MyApp, then I can provide an action that starts the Voice Input, but I'd like the google voice search app to be able to start my application when certain key phrases are spoken.
As I understand you want Google Voice Search application to launch your application when you say a special key phrase. I think that at the present moment there is no possibility to add your functionality in the Google Voice Search application (there is no API for this).
However, you can implement your own Voice Search application in the following way:
You can create an AppWidget and put it on the desktop.
When a user click on this AppWidget you can call your service and
from this service launch voice recognition activity.
This activity will return the result of the recognition
(http://developer.android.com/resources/articles/speech-input.html)
which can be processed in the service. During this you can compare a
result of the recognition with yours predefined strings for
application launching and if there is a match then you can simply
call needed application.

I'm able to integrate Android widgets with Google Assistant. And want to have some voice command experience.
For example the CREATE_CALL intent, if user is trying to call Alice by saying call Alice with some app, and if there are 2 Alice in my app, is it possible for me to response with a widget showing 2 Alice, and asking user by voice, and user can choose which one to actually call, all by voice? Can it be done by SpeechRecognizer API?
Broadly speaking, App Actions do not have a voice conversation experience. There are some tricks you can pull that might head in that direction, but they are largely outside of the App Action Widget experience itself.
Can I respond with a widget showing that there are multiple matches?
Yes, you can send back a Control Widget that might allow them to choose which user they mean.
Can they speak which user?
Probably not in the way you're thinking. To use your example, they can re-invoke the CREATE_CALL BII using any of the phrases, but you can't prompt them with "Who did you mean, exactly?" and for them to just say the name.
Can I use the SpeechRecognizer API?
Not as part of a widget.
Widgets get embedded in the conversation with the Assistant.
In theory (and this is on my list to eventually test and figure out), you should be able to deep link to an Android Intent in cases such as this and open a view. While there, you could use SpeechRecognizer or just open the microphone to send audio somewhere. But this isn't done using the Widget itself.
In this scenario, SpeechRecognizer just does the Speech To Text (STT) or Automatic Speech Recognition (ASR) part of the processing. To actually match this up to phrases to determine an Intent, you would need a Natural Language Understanding (NLU) module such as Dialogflow. (But you may not need the SpeechRecognizer in that particular case, since Dialogflow can also take an audio stream to do the ASR part for you.)
I would like to know when my app has been launched by voice control ("Ok Google, launch MyApp") in order to present the users a different activity where they can interact using their voice.
The idea is "if the user launches the app using the Ok Google command, he probably wants a hands-free interaction".
Is there a way to know it? Intent categories and flags don't seem helpful.
I'm making an app that will work with Android Wear,
And I wanted to implement a command into Google's "Ok Google" option.
I saw this page:
http://developer.android.com/training/wearables/apps/voice.html
But it's related only to apps that include Activities in the Android Wear.
I wanted to ask:
Can I add custom commands? I mean, those who does not start with the word "Start"?
Can I add commands that will do another thing than just opening the app? Like running a method?
If it's not the place to ask this, can you give me an email/link to Google Developers help/support? thanks.
For apps that run on the Android Wear Device:
No, the list of system-provided voice actions is fixed (and listed here). You can set your application to be able to respond to them (for example, to take a note), but you cannot add new ones.
Yes. When already inside your app, you you can use startActivityForResult() using the ACTION_RECOGNIZE_SPEECH to get voice input. You could then use the returned string to execute whatever you want.
Meanwhile, if you're just displaying notifications from an Android app running in a handheld, then you cannot presently have voice actions at all (at least in a literal sense). What you may have, though, is a notification action that requests voice input. That input will then be passed as an extra in the Intent that is delivered to the app in the handheld.
Is there any way to register with android speech recognition service and make it hijack all the input that begins with specified keyword? Like for example now on modern android device if you hold down search button then speech detection is initialized and if you say something that begins with "navigate to" then navigation app is started instead of browser. Can this be done for arbitrary app?
I've got an idea for an android app, I want to be able to say commands and have the application listen out for these and perform some action.
For example, I want my app to sit idle and listen for my voice, when it hears me say "start", the app will start doing something until I say "stop".
The idea is to lay the phone down and not have to physically touch it in order to control my app.
Would this be possible with any current APIs? If so which ones should I look into?
You can take a look at the Google voice commands.

Alternatively, if you want to customise your application, you can use the google voice service and write an activity that will invoke the voice service and return you the result.
Check out the below link for the sample application.
