The automobile manufacturers had the right idea years ago. Make it easy to change the temperature in your vehicle. Just say “cooler” or “warmer.” That project went about as well as their GPS interfaces are progressing today. So let’s give credit where credit is due. Apple’s Siri revolutionized voice recognition by making it something really useful on the smartphone. If you’ve wondered who Siri actually is, wonder no more. You’re in for a pleasant surprise. Meet Siri from Australia. And Siri U.S.A.:
Google, of course, is not one to be left behind. There was a reason they were offering to transcribe your voicemails for free all those years. They were putting in place the building blocks for a similar system on Android-based phones. Hey, Siri. Meet “OK, Google.” And the competition has transformed both products into incredibly useful additions to every smartphone.
Then the latest Silicon Valley Wannabe got into the picture. Let me introduce Alexa for your kitchen or living room masquerading as Amazon’s Echo, a fascinating new half-baked product. If the Echo weren’t so transfixed with selling you music and other stuff from Amazon, it could be a terrific product. Not to be outdone, Google wasted little time introducing their look-alike, OnHub, which makes half-baked look really useful. OnHub does absolutely nothing but serve as a home router with more antennas than the Mars Rover. And now both Apple and Google are circling back to the automobile promising to revolutionize the way in which you talk to or even drive your car. Stay tuned. It’s going to get interesting. And, on the living room front, you’re probably going to need to buy another round of hardware. Even though many building blocks were in place with OnHub, Google left out a microphone… unless they use the one on your smartphone or watch. 😉
So what does all of this have to do with Asterisk® and VoIP telephony? Well, nothing actually… until today. Most of the cool things you can do with your smartphone or sitting in your living room simply weren’t available using a Plain Old telephone. We decided to fix that.
For the tinkerers and experimenters of the world, Google has generously offered free access to their voice recognition software. And today we’ll show you how to put it to good use. In the time it takes to drink your morning coffee, you’ll have a platform on your PBX that’s every bit as capable as Siri. And it’s all free!
Meet Star! When we’re finished today, you’ll be able to pick up any telephone and dial * to obtain the latest weather, news, stock prices, sports scores, time of day, and anything else that an almanac at your fingertips provides. In addition, you’ll be able to call anyone by saying their name or phone number. Not bad for free, huh? Down the road, we’ll work on adding text messaging, email, and scheduling reminders. But today’s release should whet your appetite for what’s possible.
Putting in Place the Star Platform
We don’t own or control most of the components that actually make Star work! That means you’ll need to sign up (for free) for a couple key pieces before the puzzle actually takes shape. Here’s the three-step process.
First, install one of the Certified Incredible PBX builds on either a dedicated server, a virtual machine, or in the Cloud. This tutorial will walk you through the easiest 20-minute installation procedure.
Second, you’ll need to obtain and set up the credentials for two of the third-party components that will bring Star to life. You’ll need a Google Speech Recognition key and a Wolfram Alpha App-ID. Then add an AsteriDex entry to tell Star the zip code of your hometown, and you’re ready to go.
Third, you’ll spend less than a minute installing the Star software on your server.
1. Adding Speech Recognition Support to Incredible PBX
2. Using the same account, create a new Speech Recognition Project.
3. Click on your newly created project and choose APIs & auth.
4. Turn ON Speech API by clicking on its Status button in the far right margin.
5. Click on Credentials in APIs & auth and choose Create New Key -> Server key. Leave the IP address restriction blank!
6. Write down your new API key or copy it to the clipboard.
7. Log into your server as root and edit the speech recognition script:
nano -w /var/lib/asterisk/agi-bin/speech-recog.agi
8. When the nano editor opens, go to line 70 or so and look for:
my $key = "". Insert your API key from Step #6 above between the quotation marks and save the file: Ctrl-X, Y, then Enter.
9. Finally, let’s be sure you have all the necessary packages in place to support text-to-speech and speech recognition:
yum -y install perl-XML-Simple libesd.so.0 sox perl-libwww-perl
If you’re not on the Incredible PBX platform:
yum -y install mpg123
2. Adding Wolfram Alpha Support to Incredible PBX
To use Wolfram Alpha by phone, you first must obtain a free Wolfram Alpha APP-ID. Then issue the following command replacing APP-ID with your actual ID. Do NOT change the yourID portion of the command:
sed -i "s|yourID|APP-ID|" /var/lib/asterisk/agi-bin/4747
3. Adding Your Hometown ZIP Code to AsteriDex
1. Using a browser, visit the IP address of your server.
2. Click on the Nerd Vittles AsteriDex button in the Kennonsoft GUI.
3. Click on the Admin tab in AsteriDex.
4. In the Add Entry column, enter the following data using your hometown ZIP code:
Contact Name: Weather
Contact Phone: 947
Dial Code: your local 5-digit ZIP code
5. Click the Add New Record button to save your entry.
Installing or Upgrading Star
We’ve designed the Star install so that you also can easily update the application by simply running the install-star command again. After logging into your server as root, here are the commands to install or upgrade your Star application:
cd /root wget http://incrediblepbx.com/install-star.tar.gz tar zxvf install-star.tar.gz rm -f install-star.tar.gz ./install-star
10/10 UPDATE: Star apparently was too popular for Google to absorb, and they’ve imposed new limits on TTS playback. So, for the time being, we’ve switched Star back to FLITE for text-to-speech. To update your server, just run the installer again:
Taking Star for a Spin
Here’s a quick summary of the available commands that Star currently supports:
And here are some sample Wolfram Alpha queries to get you started:
Weather in Charleston South Carolina
Weather forecast for Washington D.C.
Next solar eclipse
Who won the 1969 Superbowl? (Broadway Joe)
What planes are overhead? (flying over your server’s location)
Ham and cheese sandwich (nutritional information)
Holidays 2015 (summary of all holidays for 2015 with dates and DOW)
Medical University of South Carolina (history of MUSC)
Star Trek (show history, air dates, number of episodes, and more)
Apollo 11 (everything you ever wanted to know)
Cheapest Toaster (brand and price)
Battle of Gettysburg (sad day 🙂 )
Daylight Savings Time 2015 (date ranges and how to set your clocks)
Tablets by Samsung (pricing, models, and specs)
Doughnut (you don’t wanna know)
Snickers bar (ditto)
Weather (local weather at your server’s location)
