Halle, Thank you for your suggestion. I went through the class documentation and also played around with disabling the properties.

It looks like the:

OEPocketsphinxController.sharedInstance().disablePreferredBufferSize = true

is the one that is actually having an effect. I do not disable anything else now and the loudness issue still persists. The volume increases whenever i start the listening.

Function:

func startListening() {
OEPocketsphinxController.sharedInstance().disablePreferredBufferSize = true

do {
try OEPocketsphinxController.sharedInstance().setActive(true)
} catch {
print(error)
}

OEPocketsphinxController.sharedInstance().startListeningWithLanguageModelAtPath(lmPath, dictionaryAtPath: dicPath, acousticModelAtPath: OEAcousticModel.pathToModel(“AcousticModelEnglish”), languageModelIsJSGF: false)
}

This part is from a previous reply of yours from a different post.

The loudness thing is less clear. I don’t know the reason for that, but my best guess is that it is related to the route. Playback can either be routed to the external speaker or the ear speaker and one is much louder than the other. Different audio sessions have different default routes and need to be overridden to get different results. PocketsphinxController does re-route to the louder speaker, but it is possible that something about the session mixing is causing it to not successfully do that and then it is only when the new session is created that the sound is fully routed to the speaker. It could also be due to a side effect of the mixing setting, for instance if it does some kind of active volume reduction on the assumption that there are two output streams that have to be combined without clipping.Lastly it could just be a difference between the two different audio session settings that is more noticeable when the session is returned to ambient.

The function i am using to start listening is:

func startListening() {
OEPocketsphinxController.sharedInstance().disablePreferredSampleRate = true
OEPocketsphinxController.sharedInstance().disablePreferredBufferSize = true
do {
try OEPocketsphinxController.sharedInstance().setActive(true)
} catch {
print(error)
} OEPocketsphinxController.sharedInstance().startListeningWithLanguageModelAtPath(lmPath, dictionaryAtPath: dicPath, acousticModelAtPath: OEAcousticModel.pathToModel(“AcousticModelEnglish”), languageModelIsJSGF: false)
}

My question is why does the volume of the bluetooth headset get really loud whenever i start listening. It really is very loud.
The loudness goes away when i stop the audio session (setting setActive to false) that i am usng for TTS (using AVSpeechSynthesizer). The session i use for my TTS is set with AVAudioSessionCategoryPlayback category and with the DuckOthers options.
But every time i use OpenEars it appears again. Any advise is highly appreciated.

I am also attaching the while log below. Hope it helps.

Thank You.

Hi thanks once for your insights.

So i got it to work by setting:
OEPocketsphinxController.sharedInstance().disablePreferredSampleRate = true OEPocketsphinxController.sharedInstance().disablePreferredBufferSize = true

The error still remains like the previous log i copied. If needed please let me know if you need a more detailed log or more information.

But now the loudness increases after it has completed. I read an existing post with the same issue. Is there anything specific i can try, like what audio mode to try or anything else.

Thank you for your help.

The loudness thing is less clear. I don’t know the reason for that, but my best guess is that it is related to the route. Playback can either be routed to the external speaker or the ear speaker and one is much louder than the other. Different audio sessions have different default routes and need to be overridden to get different results. PocketsphinxController does re-route to the louder speaker, but it is possible that something about the session mixing is causing it to not successfully do that and then it is only when the new session is created that the sound is fully routed to the speaker. It could also be due to a side effect of the mixing setting, for instance if it does some kind of active volume reduction on the assumption that there are two output streams that have to be combined without clipping.Lastly it could just be a difference between the two different audio session settings that is more noticeable when the session is returned to ambient.

i forgot to mention, i had turned the n best hypothesis on, so it was in an array.

[bhavin]

Thank you for your quick response.
Sorry About that. I turned on OELogging and turned verbose off for now. The log shows there seems to issue with audio routing through the bluetooth headset.

Finally it picket up the word ‘NO’ as default i guess. Please can help me out.
Thank you once again.
