What prediction information is available from deepspeech inference

Hi, I'm using the deepspeech python package to make a speech-to-text
inference on a wav file. I see some output like this:

Loading model from file models/output_graph.pb
Loaded model in 0.249s.
Loading language model from files models/lm.binary models/trie
Loaded language model in 1.428s.
Running inference.
yes
Inference took 9.582s for 5.000s audio file.

Does this mean that the model predicted that my wav file contained the
word 'yes'? Is there an estimated confidence/accuracy score on this
prediction? Were any other files with prediction information created?

Is it possible to get timestamps on the predicted text? For example, the
model predicted that the wav file contained someone saying the word
'yes' starting at 1.000sec and ending at 1.010 sec.

Currently there is no way to produce timestamps. Adding such would
require a bit of work and will likely, if it happens, be part of a
0.3.0, or later,
release.

slash ' if it happens slash ' - do you mean if release 0.3.0 happens or if the
feature is included in the release?

Sorry. 0.3.0 will happen. What I mean is if the feature is included in
the 0.3.0 release.

Cool, thanks for pointing me to the release projects,
. I'm interested in this
feature and will have some time extra time over the next month. My
background is more academic (understanding research) than building
production code, but I have contributed to open source projects before.
Is this github
issue a good place
to share learnings and collaborate?

I guess that collaborating on fixing the issue should happen on that
issue, yes. And opiniated discussions on the issue itself makes sense
there
