An Algorithmic Investigation of the Highfalutin 'Poet Voice' - Atlas Obscura
'It’s easy to make fun of Poet Voice. But its proliferation across the space of academic poetry may have more serious implications as well. In a 2014 essay, “Poet Voice and Flock Mentality,” the poet Lisa Marie Basile connects it to an overall lack of diversity in the field, and a fear of breaking the mold. The consistent use of it, she writes, “delivers two messages: I am educated, I am taught, I am part-of a group … I am afraid to tell my own story in my own voice.”'

'DolphinAttack: Inaudible Voice Commands' [pdf]
'Speech recognition (SR) systems such as Siri or Google Now have become an increasingly popular human-computer interaction method, and have turned various systems into voice controllable systems(VCS). Prior work on attacking VCS shows that the hidden voice commands that are incomprehensible to people can control the systems. Hidden voice commands, though hidden, are nonetheless audible. In this work, we design a completely inaudible attack, DolphinAttack, that modulates voice commands on ultrasonic carriers (e.g., f > 20 kHz) to achieve inaudibility. By leveraging the nonlinearity of the microphone circuits, the modulated low frequency audio commands can be successfully demodulated, recovered, and more importantly interpreted by the speech recognition systems. We validate DolphinAttack on popular speech recognition systems, including Siri, Google Now, Samsung S Voice, Huawei HiVoice, Cortana and Alexa. By injecting a sequence of inaudible voice commands, we show a few proof-of-concept attacks, which include activating Siri to initiate a FaceTime call on iPhone, activating Google Now to switch the phone to the airplane mode, and even manipulating the navigation system in an Audi automobile. We propose hardware and software defense solutions. We validate that it is feasible to detect DolphinAttack by classifying the audios using supported vector machine (SVM), and suggest to re-design voice controllable systems to be resilient to inaudible voice command attacks.'

Targeted Audio Adversarial Examples
This is phenomenal:
We have constructed targeted audio adversarial examples on speech-to-text transcription neural networks: given an arbitrary waveform, we can make a small perturbation that when added to the original waveform causes it to transcribe as any phrase we choose.

In prior work, we constructed hidden voice commands, audio that sounded like noise but transcribed to any phrases chosen by an adversary. With our new attack, we are able to improve this and make an arbitrary waveform transcribe as any target phrase.

The audio examples on this page are impressive -- a little bit of background noise, such as you might hear on a telephone call with high compression, hard to perceive if you aren't listening out for it.

Where do 'mama'/'papa' words come from?
The sounds came first — as experiments in vocalization — and parents adopted them as pet names for themselves.

If you open your mouth and make a sound, it will probably be an open vowel like /a/ unless you move your tongue or lips. The easiest consonants are perhaps the bilabials /m/, /p/, and /b/, requiring no movement of the tongue, followed by consonants made by raising the front of the tongue: /d/, /t/, and /n/. Add a dash of reduplication, and you get mama, papa, baba, dada, tata, nana.

That such words refer to people (typically parents or other guardians) is something we have imposed on the sounds and incorporated into our languages and cultures; the meanings don’t inhere in the sounds as uttered by babies, which are more likely calls for food or attention.

How the NSA Converts Spoken Words Into Searchable Text - The Intercept
This hits the nail on the head, IMO:
To Phillip Rogaway, a professor of computer science at the University of California, Davis, keyword-search is probably the “least of our problems.” In an email to The Intercept, Rogaway warned that “When the NSA identifies someone as ‘interesting’ based on contemporary NLP methods, it might be that there is no human-understandable explanation as to why beyond: ‘his corpus of discourse resembles those of others whom we thought interesting'; or the conceptual opposite: ‘his discourse looks or sounds different from most people’s.' If the algorithms NSA computers use to identify threats are too complex for humans to understand, it will be impossible to understand the contours of the surveillance apparatus by which one is judged.  All that people will be able to do is to try your best to behave just like everyone else.”

Sirius: An open end-to-end voice and vision personal assistant and its implications for future warehouse scale computers
How to build an Intelligent Personal Assistant:

'Sirius is an open end-to-end standalone speech and vision based intelligent personal assistant (IPA) similar to Apple’s Siri, Google’s Google Now, Microsoft’s Cortana, and Amazon’s Echo. Sirius implements the core functionalities of an IPA including speech recognition, image matching, natural language processing and a question-and-answer system. Sirius is developed by Clarity Lab at the University of Michigan. Sirius is published at the International Conference on Architectural Support for Programming Languages and Operating Systems (ASPLOS) 2015.'

How Emoji Get Lost In Translation
I recently texted a friend to say how I was excited to meet her new boyfriend, and, because "excited" doesn't look so exciting on an iPhone screen, I editorialized with what seemed then like an innocent "[dancer]". (Translation: Can't wait for the fun night out!) On an Android phone, I realized later, that panache would have been a put-down: The dancers become "[playboy bunny]." (Translation: You’re a Playboy bunny who gets around!)
