[Resolved] Volume control with text-to-speech

Hi,

This isn’t expected behavior — which device are you seeing this with, which OS version, and have you made any changes to AudioSessionManager (and have you used AudioSessionManager as described)? Is it happening in the sample app?

Oops, please disregard the last list of errors. I was mistakenly trying to compile a simulator version. Now I am looking into the AudioSessionManager process to see if I missed something.

Hiya,

Hmm, every issue you’re mentioning sounds like you’ve missed some steps in the instructions. There should be no errors when compiling a simulator version, the only difference is that the simulator driver is less accurate doing recognition.

Also, if the sample app is crashing for you, you can turn on the logging and see why. I’d start fresh and give some extra time to the instructions.

The sample program crashes at:
audioDevice->recordData = 1; (line 763) in ContinuousModel.mm with a EXC_BAD_ACCESS signal.

Did you download the .902 version that has the old xcode 3 instructions to use as a helper for that process? I don’t really support Xcode 3 anymore and it’s been a while since it was current, so it might be a good idea to consider upgrading since 4 is free and has some nice new stuff.

[EDIT: I see you are downloading the old version.]

I actually preferred the UI of 3 myself, but at this point it causes me more trouble than its worth to be out of step with the current version.

Ah, I didn’t realize this is what you were referring to. That is not mentioned until the “Using OpenEars In Your App” section, and so I did not make the immediate connection to use it in the testing of the sample program. Silly, I know. :)

So, first things first, the Sample Project runs fine on the Simulator. On my iTouch, I get the bad access, and I believe this would be the relevant part of the log:
2011-10-17 10:12:23.062 OpenEarsSampleProject[2543:5d03] OPENEARSLOGGING: Starting openAudioDevice on the device.

2011-10-17 10:12:23.095 OpenEarsSampleProject[2543:5d03] OPENEARSLOGGING: openAudioDevice failed

Also, I have gone this far (up to getting the sample program running), looking at both the Xcode 3 and 4 instructions, and have done everything mentioned. I have considered upgrading to Xcode 4, but I do prefer the Xcode 3 interface, and since I have no requirements at this point that require me to upgrade, I am hesitant to do so.

:S I sincerely apologize for having overlooked that post!

So here is my current state of affairs:
I added the AudioSessionManager to my code in the following way:
In MyAppDelegate.h

@class RootViewController;
@class AudioSessionManager;

@property (nonatomic, retain) UIWindow *window;
@property (nonatomic, retain) AudioSessionManager* myAudioSessionManager;
@end


In MyAppDelegate.m

...
#import "AudioSessionManager.h"
...
@synthesize myAudioSessionManager;
...
- (void) applicationDidFinishLaunching:(UIApplication*)application
{
...
[self.myAudioSessionManager startAudioSession];
}

- (void)dealloc {
[myAudioSessionManager release];
[[CCDirector sharedDirector] release];
[window release];
[super dealloc];
}


As soon as I added the line: [self.myAudioSessionManager startAudioSession];
all of my sound goes away.

If I comment out all of the AudioSessionManager code, I hear the Flite voices just fine, and oddly enough they seem much louder than yesterday, though I did not change the code or settings in that particular project….

Do you have other audio session code in your app (check by searching case-insensitively for the string audiosession)? Can you please verify that this issue is occurring or not occurring with the sample app?

My mistake, it is a gen2 iTouch.
I have no audio session in my code, but I am also using Cocos2d, so I don’t know if it is overriding something.
I ran the sample app (after commenting out all PocketsphinxController code). I do not hear anything when I load up the app.

Let me post the logging now.

And here it is with AudioSessionManager:

Okay, I can most certainly do that. I will post the results here as soon as I get a moment to go through it.

Okay, so it looks like I found the main issue area:
If I comment out
UInt32 audioCategory = kAudioSessionCategory_PlayAndRecord; // Set the Audio Session category to kAudioSessionCategory_PlayAndRecord.
OSStatus audioCategoryStatus = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(audioCategory), &audioCategory);
if (audioCategoryStatus != 0) {
OpenEarsLog(@”Error %d: Unable to set audio category.”, (int)audioCategoryStatus);
}

Then I get the error messages from the next two “if’s”, so I also have to comment them out:
UInt32 bluetoothInput = 1;
OSStatus bluetoothInputStatus = AudioSessionSetProperty(kAudioSessionProperty_OverrideCategoryEnableBluetoothInput,sizeof (bluetoothInput), &bluetoothInput);
if (bluetoothInputStatus != 0) {
OpenEarsLog(@”Error %d: Unable to set bluetooth input.”, (int)bluetoothInputStatus);
}

UInt32 overrideCategoryDefaultToSpeaker = 1; // Re-route sound output to the main speaker.
OSStatus overrideCategoryDefaultToSpeakerError = AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof (overrideCategoryDefaultToSpeaker), &overrideCategoryDefaultToSpeaker);
if (overrideCategoryDefaultToSpeakerError != 0) {
OpenEarsLog(@”Error %d: Unable to override the default speaker.”, (int)overrideCategoryDefaultToSpeakerError);
}

After commenting all this out the following log is the result (see my next post) and sound plays.

Here is the log when I play a sound:

Okay, I replaced with kAudioSessionCategory_MediaPlayback. There are a couple log errors, but I get sound:

And how are your volume levels with speech when using kAudioSessionCategory_MediaPlayback?

All righty, I will add that fix when I have time to test it more extensively. Thanks for the bug report and testing.
