Android :: Speech Recognition - Limit To Match Numeric Input
Nov 1, 2009
I want to use the SR api to handle commands in my application. I know at any given point in my application what the valid commands would be at that point so would like to limit the results that the SR is matched against. For example, if the only valid commands were "Yes" or "No" I would like to be able to restrict the SR to only try and match against those two words. Otherwise on full vocabulary I get "Snow" and other false words. Limiting the vocabulary should make matching 90%+ accurate on limited words. Is this possible? Also, can I limit the SR to only match numeric for number input only? The internal dialer seems to be able to do this sort of this, so can I?

Is there a way to use an audio file as input to speech recognition? If not, is this feature expected in the foreseeable future?
A separate question (and this is going to sound ridiculous, but it might actually be okay for a joke app I'm thinking about): Would it be possible to play audio out of an Android handset, while at the same time having a recognizer listen to it via the microphone? (Guess I could just try it.)

How to I properly parameterize the speech recognizer so that it can more easily recognize the words that the user will probably say?
As far as I can tell there is no way.
I believe this site is wrong: http://www.4feets.com/2009/04/speech-recognition-in-android-sdk-15/
CODE:............
Will give a hint to the recognizer that you might say those words. However, it appears to do absolutely nothing. It also conflicts with the google documentation which says:
"An ArrayList of the potential results when performing ACTION_RECOGNIZE_SPEECH. Only present when RESULT_OK is returned." This hints that the array is a return value NOT an input.
To test this out try adding: ArrayList< String > potentialResults = new ArrayList< String >(); potentialResults.add("cumin"); and try to get the speech recognizer to recognize it. You will find it very difficult.
How to properly control the speech recognizer?

I am developing an app that uses the speech recognizer but I only want the speech recognizer to listen for speech for x number of seconds regardless of when the last speech input was or was not recognized. I looked through the speech recognizer documentation and I didn't see parameter to set the exact time the speech recognizer runs for. How I could accomplish this?

Is Android Speech recognition only available for english? I tryed to set EXTRA_LANGUAGE in the RecognizerIntent but it doesn't work. EXTRA_LANGUAGE - Optional language override to inform the recognizer that it should expect speech in a language different than the one set in the getDefault(). Do you know anything about this?

From what I've read, speech recognition is available for 3 languages: English (UK, US, Au ..), Japanese and Chinese (Mandarin). Does anyone know more details about how to switch between these languages? Is there a way to know (programatically) which language is active for speech recognition on a certain device? (maybe in Japan the only have Japanese ... but can I get this information somehow ... like a property or anything?).

I am trying to build an application (which would use the Hindi language and other regional languages) to get speech voice commands.I also need text to speech functionality in my application.I was wondering if there was any way I could get a speech recognition library on Android? I did a quick Google search and found a couple of libraries for Hindi on the Internet but I am not sure if I can include them in my Android project. Can I?

Does anyone have a recommendation for a microphone to use to demo speech recognition.

I have an app I am working on that does some math on a few variables and outputs the answer. Well that's the plan anyway. Being a total n00b at Android & Java I am not sure of a couple of things.1) I have created text fields in the layout file for user to enter values. Instead of text fields should I use numerical value fields, if such a thing exists? 2) How can you convert from a text field to a numerical value and back again?

I use the following code to pop up the soft input keyboard in my Activity
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); imm.getInputMethodList(); imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); This displays the alphabetic keyboard. But I want to display the numeric keyboard. Please note I know that using setInputType() works when used with an Edittext or a TextView but I want to be able to display the keyboard without an input area such as an Edit Text and simply listen to the key presses on the keyboard. Can anyone confirm whether this is possible and if so how can it be achieved?

I am making a math program that reads in numbers from an edit text box, and creates / LU factors a matrix. When a user clicks into this field, the regular keyboard shows. It would be easier for the user if it were a numeric keyboard. When I use android:input Style="number" the amount of numbers allowed to be entered into the field is 1. How do I bring up the numeric keyboard without limiting the ability to enter multiple numbers?

I am trying to do something that I thought would be simple, yet I still haven't found the right approach. I have a Edit Text field that should only accept unsigned decimal entries. Using android:input Type="number Decimal" in my layout xml file achieves this, however the soft keyboard that is raised with this input Type is the standard keyboard but just uses the alternate view with the number row on top. This is far from ideal for a field that only allows numbers. A much better soft keyboard for numeric entry is the "phone" one. It has all of the numbers and a decimal. Perfect!! Well, except that for the life of me I cannot figure out how to use both the phone keyboard AND allow only numeric entry. I've tried everything I can think of but if I use the phone soft keyboard then the input field also allows things like "(" and any of the other symbols available on that keyboard. Is there any way to get the nice big numeric buttons of the phone keyboard along with only allowing decimal entry?

I've been doing some usability testing on a website I'm developing, using an Android phone and an iPod touch. In both cases, when entering a numeric field (time, distance in metres, etc) I have to take a manual step to change the keyboard layout to show digits. As the app will only accept numeric values in the text box, I'd like to save the user the inconvenience and tell the device "switch to the number pad for this input".

I have installed the vlingo app which works with no problem (so far). However, when I download and run the app Talk to Me, and click the microphone, it says that "Speech Recognition Tool is not currently installed". I have searched all over Google to try and find what exactly it is that I need to install on my Wildfire to enable this app, and a couple of others, to recognise my speech. What I need to do to enable speech recognition.

My speech recognition app needs to work without human intervention, so the situations where the "No speech heard" or the "No matches found" dialogs come up and require a button press are a problem.
Is there a way to prevent this dialog from displaying?
Is there a way to programming perform the button click?
Is there a way to programmatically close the dialog?
This is how I'm firing the RecognizerIntent:

I AM able to turn on "personalize speech recognition" via the settings in voice search, but on my google dashboard the speech section is missing and I see no evidence that google speech recognition accuracy is improving in any way. Ive tried clearing the app data and enabling search history without success.
I have only 1 gmail account linked to this phone and everything pertaining to that account (calendars, app store, etc.,) is updating correctly.
Im running ICS stock rom on a rooted HTC vivid with ATT service. I have voice search 3.0.1. The app store only has version 2.1.4. Id gladly uninstall 3.0.1 and install 2.1.4 from the app store if it would fix this problem but im worried uninstalling voice search could cause additional problems.

But before we engage in arguments on the politics of actively hiding the file system to computer users and restricting access to their devices... WHERE Google stores its Offline Speech Recognition Language Files?
I accidentally discovered that Offline Speech Recognition seems to have been bundled with Google Search somehow because if Google Search is disabled, so is Speech Recognition and looking at Google Search in Application Manager, one can notice that the data storage is proportional to the size of the downloaded language files, but so far have been unable to locate where on the device these files are stored, so that they don't need to be downloaded again.

For some reason in the past day or so, my speech recognition function makes a bleep noise when I activate it. I am pretty sure it never did before (I don't like beeps and bleeps). All my other settings are on vibrate or mute. I have gone through the various sound settings in the system menu and the language and input and can't find a way to turn it off. How to get that sound off? Or even tell me how it might have turned on?

It seems to me that the method "speak" of class TextToSpeech only works in method onInit or on Utterance Completed. However, onInit and onUtteranceCompleted don't have any parameter for passing strings. In the following code, I tried to define a global string arraylist outside the methods and used the arraylist for string input.For some reason , it didn't work out.But the engine did speak "did you sleep well". public class TTS extends Activity implements OnInitListener,OnUtteranceCompletedListener,Runnable ArrayList<String> content=new ArrayList<String>();
int MY_DATA_CHECK_CODE=50;
private TextToSpeech mTts;
public void onCreate(Bundle savedInstanceState) {
content.add("test");
content.add("another test");
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
mTts = new TextToSpeech(this,this);
} else { // missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(
TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);

if(status==TextToSpeech.SUCCESS){
mTts.setLanguage(Locale.US);
mTts.setOnUtteranceCompletedListener(this);
String myText1 = "Did you sleep well?";

I am looking at doing speech recognition in android. The program needs to have continuous speech recognition. The library only needs to be about 10 words. I have considered using Googles api, but I don't think it will work. (I cannot have anything covering the screen). I have been looking into other ways but nothing seems like it will work. Is it possible to use java's speech recognition library, or is there any other way of going about this?
In summary
1. Need continuous speech input
2. 10 words at max
3. can train if necessary
4. overview of program - display screen, wait for voice input or touch input, update screen repeat
5. cannot cover what is being displayed on the screen

I would like to show a custom input field (specifically, one containing only 9-0 and two extra buttons containing decimal separator (, or .) and a delete button). I could create a custom IME, but (as far as I know) that would have to be set by the user as the system-wide input method. Is there a way to implement an input method and bind it to a specific input field?
