Re: [DEVEL] Saera: Siri clone for Maemo 5
 

Ok, I'll add a language selector. Saera will be able to respond in Spanish but you'll have to talk to her in English, because I haven't separated the keywords out into their own module yet.

Everyone: New version of Saera with much better accuracy!!
Gory details: It's using a much smaller model, compiled from a list of sentences I hand-typed that I imagine one might say. It will recognize other sentences than the ones I typed, but only ones with the same words (because the dictionary is generated from the corpus). It would be quite a help if other people could create other sentences to expand the model (see corpus.txt for example/what I have so far).

Also: could someone point me to a good packaging tutorial? I tried the dh_make route but got hopelessly entangled and lost.

Re: [DEVEL] Saera: Siri clone for Maemo 5
 

While this may be great for general use, it may be worth keeping both modes depending on what you're doing. Having a limited vocabulary based on input commands is great (better if it parses those and auto-generates the library at startup if it's changed); but if someone wants to use it for entry for say a text message, it may be desirable to have more words and less accuracy. :)

Re: [DEVEL] Saera: Siri clone for Maemo 5
 

I'm working on it. Pocketsphinx allows for context switching of models as I understand it, so it should be possible; i.e. you say "Text John Smith let's go to Pizza Hut", and the limited model recognizes "Text John Smith" and then switches to the extended model to parse the text itself.

what can i do?

Re: [DEVEL] Saera: Siri clone for Maemo 5
 

Somone else had this problem earlier. You are missing the packages pocketsphinx-lm-en-hub4wsj and pocketsphinx-hmm-en-hub4wsj.

Re: [DEVEL] Saera: Siri clone for Maemo 5
 

That sounds like a good idea.

Would it be possible for the limited model to be compiled on the user's device? I ask because I think the limited model should be based on the commands that are standard+locally configured, and the contact names in the user's contacts.

Re: [DEVEL] Saera: Siri clone for Maemo 5
 

I believe so. I have to do something like that for contacts at least anyway, although I should include app names as well.

Re: [DEVEL] Saera: Siri clone for Maemo 5
 

Just tell me when it is ready and I will translate the keywords.

Re: [Announce] Saera: Siri clone for Maemo 5
 

Ok. :)
In the GTK version first, the QT version doesn't support showing markers & routing result at the moment. There are also actually no versions, just different GUIs with a shared backend. So you can either get the package from Extras-Devel and ignore the Qt dependencies or just clone the github repo and run modRana with:
Well, once I'm done with the CLI stuff anyway. :)

Ok, good idea. I'll keep it in mind while implementing it. :)

BTW, modRana has a built-in POI database - the points are stored in categories and each has a name and a description. You mentioned parsing contacts - maybe the POIs would be also usable for something similar ? :)

Re: [Announce] Saera: Siri clone for Maemo 5
 

Do POIs usually have names that are regular words? (I haven't actually used POIs in ModRana before.) If so, that should be pretty easy to deal with, but otherwise it will have to prompt for pronunciation.
