Dates with Siri

Before I get any further, let me tell you that some of what I’m going to say here was already covered by David Sparks in this post from almost six years ago. This was just a year and a half after the “beta” introduction of Siri with the iPhone 4S, and David was pleased with what Siri could do. I like a lot of what Siri can do with dates, too, but there are still some frustrating blind spots and inconsistencies. In fact, with one of David’s examples, Siri isn’t as convenient as it was six years ago.

Context has always been one of Siri’s weaknesses, and that’s where it failed Casey. Any normal human being would understand immediately that a question asked in January about days since a day in December is talking about the December of the previous year. But Siri ignores (or doesn’t understand) the word “since” and calculates the days until the next December 18.

Solid collection of examples of date calculations with Siri by Dr. Drang. As he notes, it's not that Siri can't answer complex questions involving dates – it's that you often have to phrase your questions with an exact syntax that a computer program can understand. This is frustrating because Apple promotes Siri as a smart assistant that can infer context without a refined syntax. I still run into a similar problem with time zone conversions; of course, the old trick I used to rely on no longer works for me unless I preface the question with "Ask Wolfram".

Apple Adds AI Head, John Giannandrea, to Executive Team

Today Apple announced that one of its most recent high profile hires, John Giannandrea, has been added as the twelfth member of the company's executive team. His title is now Senior Vice President of Machine Learning and AI Strategy. From the press release:

“John hit the ground running at Apple and we are thrilled to have him as part of our executive team,” said Tim Cook, Apple’s CEO. “Machine learning and AI are important to Apple’s future as they are fundamentally changing the way people interact with technology, and already helping our customers live better lives. We’re fortunate to have John, a leader in the AI industry, driving our efforts in this critical area.” 

News of Giannandrea's hiring at Apple first broke in April at The New York Times. Apple didn't formally announce the hire, however, until July. And here we are just a few short months later, with another press release from Apple announcing his promotion.

Giannandrea's role involves leadership of Siri, machine learning, and other artificial intelligence projects, all of which are right up his wheelhouse due to his former role as Google's chief of search and artificial intelligence. While it's hard to say from the outside what kind of difference his influence is making at Apple, this move is a good sign that the company's pleased with his early months of work. Perhaps we'll get to see the fruits of his labors at WWDC 2019.

Apple’s Machine Learning Journal Posts Paper on How Siri Works on the HomePod in Noisy Environments

Apple’s online Machine Learning Journal has published a paper on the methodologies the HomePod uses to implement Siri functionality in far-field settings. As Apple’s Audio Software Engineering and Siri Speech Teams explain:

Siri on HomePod is designed to work in challenging usage scenarios such as:

  • During loud music playback
  • When the talker is far away from HomePod
  • When other sound sources in a room, such as a TV or household appliances, are active

Each of those conditions requires a different approach to effectively separate a spoken Siri command from other household sounds and to do so efficiently. The report notes that the HomePod’s speech enhancement system uses less than 15% of one core of a 1.4 GHz A8 processor.

Apple engineers tested their speech enhancement system under a variety of conditions:

We evaluated the performance of the proposed speech processing system on a large speech test set recorded on HomePod in several acoustic conditions:

  • Music and podcast playback at different levels
  • Continuous background noise, including babble and rain noise
  • Directional noises generated by household appliances such as a vacuum cleaner, hairdryer, and microwave
  • Interference from external competing sources of speech

In these recordings, we varied the locations of HomePod and the test subjects to cover different use cases, for example, in living room or kitchen environments where HomePod was placed against the wall or in the middle of the room.

The paper concludes with examples of filtered and unfiltered audio from those HomePod tests. Regardless of whether you’re interested in the details of noise reduction technology, the sample audio clips are worth a listen. It’s impressive to hear barely audible commands emerge from background noises like a dishwasher and music playback.

Google Integrates Assistant App with Siri Shortcuts on iOS

Google released an exciting update for its Assistant iOS app today, bringing support for Siri shortcuts and, for the first time, opening lines of communication between the two competing assistants.

Siri and the Google Assistant have historically been unable to work together in any way, but thanks to the opening up of Siri via shortcuts in iOS 12, that changes now. With the latest update, you can set up a shortcut in iOS to immediately, via Siri, trigger any command you'd like to give Google's Assistant.

HomeCam 1.5 Adds Shortcuts to View Live HomeKit Camera Feeds in Siri, Search, and the Shortcuts App

I previously covered HomeCam, a HomeKit utility by indie developer Aaron Pearce, as a superior way to watch live video streams from multiple HomeKit cameras. In addition to a clean design and straightforward approach (your cameras are displayed in a grid), what set HomeCam apart was the ability to view information from other HomeKit accessories located in the same room of a camera and control nearby lights without leaving the camera UI. Compared to Apple's approach to opening cameras in the clunky Home app, HomeCam is a nimble, must-have utility for anyone who owns multiple HomeKit cameras and wants to tune into their video feeds quickly. With the release of iOS 12, HomeCam is gaining one of the most impressive and useful implementations of Siri shortcuts I've seen on the platform yet.

How to Trigger IFTTT Applets with iOS 12’s New Shortcuts App and Siri

Among the actions that didn't make the transition from Workflow to the new Shortcuts app for iOS 12, built-in support for triggering IFTTT applets (formerly known as "recipes") is perhaps the most annoying one. With just a few taps, Workflow's old 'Trigger IFTTT Applet' action allowed you to assemble workflows that combined the power of iOS integrations with IFTTT's hundreds of supported services. The IFTTT action acted as a bridge between Workflow and services that didn't offer native support for the app, such as Google Sheets, Spotify, and several smart home devices.

Fortunately, there's still a way to integrate the just-released Shortcuts app with IFTTT. The method I'm going to describe below involves a bit more manual setup because it's not as nicely integrated with Shortcuts as the old action might have been. In return however, you'll unlock the ability to enable IFTTT triggers using Siri on your iOS devices, Apple Watch, and HomePod – something that was never possible with Workflow's original IFTTT support. Let's take a look.

Overcast 5: Redesigned Now Playing Screen, Search, Siri Media Shortcuts, and More

Overcast, Marco Arment's popular podcast client for iPhone and iPad, received a major update today to version 5. While I've long praised Apple's work on their built-in Podcasts app for iOS – particularly since getting three HomePods and leveraging Podcasts' support for AirPlay 2 – I also recognize the appeal of Overcast's advanced features and powerful audio effects. Sprinkled throughout Overcast's release history are design details and enhancements big and small that make it a sophisticated, versatile client for podcast aficionados who don't want to settle for a stock app. From this standpoint, despite welcome improvements to Podcasts in iOS 12, changes in Overcast 5 make it an even more attractive option that has caused me second-guess my decision to embrace Apple's native app.
