besides my app is an App about audio playing and recording. so the session lasts active when user is in my app is Reasonable。

[sunnysuhappy]

Got it.

I have changed some code in openears proj.
to stop release audiosession when in my app. this will resolve my problem currently. and I think this will not take me other problems.

Thanks a lot

i’sorry. here is the right one.

[sunnysuhappy]

hi Halle.
I have tested your openears example,and fint it also causes audioSessionRouteChange.

if there are some bugs?

[sunnysuhappy]

can i have some way to avoid route change while stopListen

[sunnysuhappy]

My I Have a Way to Control OpenEars to give me the result.now I Need to wait until it judged the silence.

sorry, i meant that i must wait several seconds for the result.because openears need silence time and to retuen results.
may I have a way to get the result rapidly with JSFG

[sunnysuhappy]

ok thanks very much

[sunnysuhappy]

Ok thanks.
If i want to recognize lots of sentences. so i think I should clean lauageModel when recognize new words to save memory. but it seems no apis.

[sunnysuhappy]

This situation happens when i use ReturnNBest mode.

[sunnysuhappy]

soory, I mean if I have a way that i can input custom audio buffer in it.instead of the api startListen.
Now i think i find the way to achieve my target.use rapidEars to have realtime recognize.but i find that rapidEars has crash when use it for server seconds, and it seems having memory leak, it always lead to a large memory useage increased every time to 100M and more

[sunnysuhappy]

ok
thanks for your reply,and i want to know if I can input audio buffer to recognize instead of a wav path.
