Neat. I'm working on a system and API for question type (factoid, polar, description, etc.) prediction and polar question answering (polar questions are 'yes-or-no' questions; Wolfram Alpha doesn't attempt these). Let me know if you are interested.

rob_mccann9• 13 years ago

Is it on github?

mgamache2• 13 years ago

I would like to hear more about your project.

Hmmm, on Mac, might be possible to simplify using system's dictation (have no idea if they have API for that, probably no, but maybe there is a way to hack it) and system's voice. So then it might be even faster, and would require mostly just Wolfram|Alpha API key.

rob_mccann9• 13 years ago

Sounds like a good idea to me, I wonder if Windows has a similar API too?

simcop2387• 13 years ago

Yes it does SAPI[1]. There's a few for linux but nothing that's become any kind of standard unfortunately, festival tends to have the best voices but is a bit of a pain to use inside another program in my experience.

In OSX 10.8 you can just hold Cmd (or is it option?) for a few seconds to get dictation for any text input system-wide.

For TTS the say command has all voices available.

Double tap 'fn'.

This has now been added

I think there will be some cool applications with this and a Rasberry PI. I'm floating around this half-baked idea of plugging Rasberry PI's into the light sockets of my home (since they're all central to the room [better for audio and microphone quality] and negates the need of running wire all over the place) so that I can have voice controlled computers in all my rooms and play music/make calls/automate my home/etc. Being able to ask the computer some random question and get an answer without having to go to my computer would be insanely cool to me :)

rob_mccann9• 13 years ago

That's the idea, this is literally just the first concept there's a whole bunch of cool things to be done. I'd love to make it possible for others to build their own extensions too.

jheitzeb• 13 years ago

Awesome project, Rob! It's amazing what can be done with some cheap hardware and some ingenuity + existing services over the internet. We just blogged about your project on Hack Things. http://www.hackthings.com/star-trek-like-computer-with-raspb...

Dwolb2• 13 years ago

Agreed with this sentiment. Something that could ease its way into the home improvement segment is an embedded linux device with microphone input, speaker output, powered off 120VAC, fits in a wall box, and input for more microphones to form an array for better listening.

rob_mccann9• 13 years ago

That's the idea behind getting it to run on the Raspberry Pi. Having it choose the mic closest to the person that says 'computer' would be cool.

jared314• 13 years ago

Android 4.1, and above, has offline voice recognition. I'm not sure about the current state of Android support for Raspberry PI, but you wouldn't have to reinvent anything.

noonespecial• 13 years ago

I've had exactly the same thoughts myself. I was thinking about using TP-Link WR703n's instead of Pi's but if they get the model A out in quantity soon enough, it would be a better choice.

Powerful computers that are so cheap you can permanently purpose them to tuning on and off a single light-bulb are a bit of a game changer if you think about it.

I'm guessing the next raft of patent trolling will follow the form "household item but with a computer/wifi in it".

laumars• 13 years ago

I've already been working on something very similar for my car as I was sick of taking my eyes off the road to change the music etc. I already have a working prototype, but there's still some work to be done before its good enough to publish.

Groxx• 13 years ago

The future is an API mashup. Neat. It does make me wince a bit thinking that the actual techniques driving all of this are locked up tight, and subject to going away whenever the owning business decides to do so. Hopefully the actual future is a little more open.

rob_mccann9• 13 years ago

Agreed, it'd be cool to develop some kind of verbal querying for the semantic web rather than relying on a proprietary knowledge base - but that's a whole other project for another day.

AJ007• 13 years ago

There is a view of the future where we query Google (or Siri) by voice and it just gives us exactly what we want.

I think a better "vision" is an open voice input engine that then connects, or even bridges, other systems via APIs.

I particularly like the idea of a service such as Zapier bridging a infinite universe of APIs to connect things together -- "computer request Uber black car when I receive a Skype call from Jim."

An input engine could create a marketplace of APIs. Commercial services, such as Uber, could profitably offer their APIs for free. Other services without a specific product may run their APIs on a cost per use basis. A mass market cost-per-use API could charge a few pennies per inquiry but still be very profitable.

Perhaps what I am describing could represent the demise of the search engine as we know it.

drakaal3• 13 years ago

It is Siri minus a lot of the language processing. I'm glad to see interest in the topic since this is the type of thing I am currently working on a http://www.stremor.com

But Wolfram alpha has a lot of things missing, and lots of the things it does are way longer than I want to hear a computer read to me.

Maybe if the author combined this with our TLDR api, and our Sentence parsring API, and our Fact search API...

(yes if you use all of our API's you can build this in about and hour and have it do a lot more) hint hint

rob_mccann9• 13 years ago

Feel free to fork and improve, I'd be interested to see how it would work with your APIs.

hnriot• 13 years ago

You're claiming to do better than wolfram alpha? Are there any online demos of your technology? The better search through semantics has been thrown around for years, but so far it's never been found to beat the traditional approach. POS and grammatical comprehension has all the usual brittleness. The best or the best is CoreNLP, but that's GPL so unlikely to be in your product unless you've licensed it.

drakaal3• 13 years ago

Check us out. We don't use CoreNLP or NLTK. we have our own because everything else sucked.

And yes I do better than wolfram alpha.

schappim• 13 years ago

You should totally hook Pi-Voice up to NinjaBlocks.com and all your connected devices!

Noelkd• 13 years ago

1. do you work for ninja blocks? 2.Just looked at Ninjablocks do they have microphones?

mgamache2• 13 years ago

I don't work for NB, but I think you could probably get an add-in board/USB solution for audio input. It's based on a Beagle Bone (ARM/Linux). It might even accept Arduino shields?

hawkw• 13 years ago

So it's open-source Siri in Python? Cool!

NotUncivil• 13 years ago

Is there an extensible framework for processing Wolfram Alpha-like natural language queries (presented as text) locally on Linux?

rob_mccann9• 13 years ago

python's nltk, I've not yet looked into it but do plan to.
