Test another android version

[brelto85]

hi,

Some users complain that the voice recognition doesn't work
In particular i have received reports from users with Acer Liquid z110 and Huawei with Android 4.0.4

How to test my app using different android version?

Thanks
Alberto

You can use the emulator to test it on different Android versions. However for a feature such as voice recognition you will need a real device.

Ok, thanks
I really have to test the voice recognition.
Do you have any idea why on some devices goes wrong speech recognition?
that library should be standard ..

 

[Erel]

Which library are you using? Can you post the relevant code?

 

[brelto85]

Sub Process_Globals
    ...
    Dim mActionVoiceRecogn As VoiceRecognition 
    ...
End Sub

Sub ImageView1_Click
    mActionVoiceRecogn.Prompt = Preference.mTrans.GetText("Tell me...")
    mActionVoiceRecogn.Listen
End Sub

The object mActionVoiceRecogn initialized in a common module

In phones where there is the anomaly appears the window of speech recognition but you do not have the time to talk.
The error appears immediatly and is "Audio Problem"

I use Phone library v2.01

 

[Erel]

Are you checking that VoiceRecognition is supported (VR.IsSupported)?

 

[brelto85]

yes and return TRUE

 

[Erel]

If you have access to one of these devices then you should check the unfiltered logs. There might be more information there.

Hi,

I was able to run the test with a device that has the problem
Here is the log when i start the voice recognition with Acer Z110
Android 2.3

You can explicitly set the Language property to "en" (English). Otherwise the device default language is used and it might be unsupported.

 

[brelto85]

the language was set after Initialize() method
how to use RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS to list languages?

 

[Erel]

It is currently not possible (without writing a library).

 

[brelto85]

tips to solve the problem?
the voice recognition on the smartphone (google search) works correctly

 

[Erel]

You can explicitly set the language to "en".

 

[brelto85]

you mean the Language property of the voicerecognition class?
in this case i have the same error

the strange behavior is that the google search with voice recognition works perfectly with all language...

 

[Erel]

Can you post the error message you get when the language is set to "en"?

VoiceRecognition supports "en" for sure. I think that there is a problem with this device microphone which is not related to the language.

 

[brelto85]

I agree with you. but how is it possible that the voice recognition google search works correctly with both languages​​?

 

[Erel]

I'm sorry but I do not know. Have you tried to reboot the device.
