 Speech Enabled Puppy |
|
In desktop technology, there are 2 desktop speech methods used. Desktop navigation and Office information insertion (i.e. Wordprocessing, and other pakages)
Can we do this in Puppy? How?
Thanks in advance.

Are you wanting something to allow partially sighted people to use puppy?
There was speakpup
speakpup thread
http://www.murga-linux.com/puppy/viewtopic.php?t=24571
speakpup blog
http://speakpup.blogspot.co.uk/
maybe Emacspeak is what your looking for?

I think he's asking about speach recognition, whereas I think speakpup was about the opposite (text to speech).
I believe there are a few options for text to speech, especially whatever you call things like jwmspeech.
But for speech recognition there aren't so many options. There is CMU Sphinx, but there don't seem to be a lot of end user applications are based on it (check out pocketsphinx though). Then there is Simon, which is KDE based. And there's another engine called Julius, but I can't see any end-user applications based on it (although I haven't looked very hard).

AFAIK, Simon uses Julius. I have done some work on TTS and STT. Festival is the top-of-line for text-to-speech, but there are several lighter alternatives which are nearly as good or just as good. Yes, speech-to-text is much more complicated. Julius seems to do a better job than sphynx, though. I use Julius for STT and either flite or svox-pico for TTS.

Thanks everyone. Yes I am referring to Speech to Text (STT) and also to "Speech to control desktop actions". (Yes, I recognize that these though similar, interact with the system/subsystems differently).
@Amigo, would you do 2 things for us
- share how you are doing STT in Puppy/Linux?
- Is your method available as a PET for Puppy?
And, does anyone know of any other Open Source efforts in the area for speech in Linux.
Thanks in advance

You may be interested in the following. It is primitive but at least its a start.

Sorry I hadn't moticed new posts in this thread. Text-to-speech is really easy by using flite, but the male voices aren't very nice. svox-pico has nicer voices. I don't create pets myself, but you can use my src2pkg tool to create them.

A major subsystem service is being made avilaible to PUPPY |

It looks like the post provided by @ETP is a major PUPPY contribution for directing Puppy to achieve work for us, vocally. THIS IS ENORMOUSLY IMPORTANT as any of us can make use of its technology to productively achieve useful work.
If you have a moment, review the post he provides us, in his earlier post.

Flite is text-to-speech. How do you do speech to text? You said you use Julius - is it an end-user application, not just a library? I think maybe I just didn't build it when I was looking into this stuff previously because it sounded like the English acoustic models weren't complete enough.

I forget the name, but there was a really old project which was used in some of the tablet distros which turned into things like Meego. But when I looked it seemed like all the copies of the website and source had disappeared 
Also, FWIW:
- Simon now supports 3 backends, CMU SPHINX, HTK (proprietary) and Julius.
- the Simon developer has recently been working on "a demo of open source speech recognition", including improving the acoustic and language model. See http://grasch.net/blog

Sorry disciple -I must have just gotten out of bed or was needing to get in bed...
For Speech-to-text I use julius as it does a better job than sphynx.
I'll have to find my source tree for you because I created a small patch to the sources to quieten the julius output for easier parsing...
OK, found them. There is a julius program that can be built under the /julius directory. But, /julius-simple contains a more concise demo application which I modifed with the following patch:

Those changes were still tentative, but make the output lots more concise.
