It seems OpenEars+SaveThatWave will record whatever used for the recognition, right? But it will generate a new wave file whenever there is a silence. Can SaveThatWave be configured to continue to save into one big wave file until [saveThatWaveController stop] is called? Or is there any way to combine those smaller wave files into one big wave file?

Thanks,

Steve

The upcoming version of SaveThatWave does this — I’m just waiting to release it along with versions 1.65 of RapidEars and OpenEars which fix an annoying bug of long standing. I really hope to have them all out in a week or so.

The new SaveThatWave feature just has the caveat that it outputs what PocketsphinxController receives while listening is in progress, so when recognition is suspended there will be a period of silence of that length. Once listening has been stopped, it will produce and notify you of a complete WAV available to you, and if the session stops prematurely it will prepare the saved audio from that session into a WAV during the next session (it’s designed primarily as a tool to let you get a test output when you’re encountering issues).

Yes, it is out and you can find it on the licensee site as a free update. If you like you can keep track of updates by subscribing to the blog RSS where I post all of the update news.

I got the new plugin and found a new method startSessionDebugRecord. I use this method to replace the place where I called start. But when can I get the wav file? After I call stop, I still couldn’t get the wav file.

Thanks,

Steve

Since the new feature captures the entire result of a listening session as the speech decoder hears it, the WAV is wrapped up and a notification is sent to you when the message [self.pocketsphinxController stopListening]; is sent.

I called [self.saveThatWaveController startSessionDebugRecord] after calling [self.pocketsphinxController startListing] and called [self.pocketsphinxController stopListing] after speaking something. But I never got the indication for the wav file. Both device and simulator seem not working. Here is the message I got for simulator:
