AI in Voice Forensics

AI is now so advanced that it can reveal far more about you than a mere fingerprint. By using powerful technology to analyse recorded speech, scientists today can make confident predictions about everything from the speaker’s physical characteristics – their height, weight, facial structure and age, for example – to their socioeconomic background, level of income and even the state of their physical and mental health.

Your voice can give away plenty of environmental information, too. For example, the technology can guess the size of the room in which someone is speaking, whether it has windows and even what its walls are made of. Even more impressively, perhaps, the AI can detect signatures left in the recording by fluctuations in the local electrical grid, and can then match these to specific databases to give a very good idea of the caller’s physical location and the exact time of day they picked up the phone.

One of the leading scientists in this field is Rita Singh of Carnegie Mellon University’s Language Technologies Institute. Interview with Ms. Singh

The world was running out of cassette tape

Although the birth and growth of audio cassettes began in the 1960s, its cultural moment took place during the 1970s and 1980s as a more effective, convenient and portable way of listening to music.

By the time I started working at KBOA in 1972, portable cassette players were finally starting to get affordable. Instead of having to coax people into a studio to do an interview we could not take a cassette recorder into “the field” and get the interview with “nat(ural) sound.” It was wonderful.

Cassette audio tapes were a part of my life for the next 30 years. During my years at the station and later — at a regional news network company — we bought a lot of audio tape cartridges from a company in Springfield, Missouri, called National Audio Company. A former coworker sent me the story below. A few excerpts:

Nobody has made audio cassette tape in this country since about 1983 or 1984. […] National Audio is set to begin production this month, having rescued a 62-foot tape-coating line weighing 20 tons from obscurity. Its former owner had converted it into a machine for making credit-card strips. […] Soon, the tape coater will be back to its original purpose, after many months of reassembly and testing. It will crank out 20,000 feet of tape per minute.

If you have (as I do) fond memories of audio cassette tapes, I think you’ll find this story worth a read.

Telemedicine

“A partnership between New York-Presbyterian (hospital) and Walgreens is pushing telemedicine further into the mainstream. NYP announced Monday that its physicians will be accessible remotely for non-life-threatening illnesses through Walgreens’ online portal and self-service kiosks at select Walgreen-owned Duane Reade locations in New York. The partnership is an expansion of NYP’s OnDemand platform for telehealth and mHealth services, which was launched in 2016. For $99 per session, patients can visit secure, private kiosks to be examined by doctors via video chat. The kiosks are also fitted with connected devices for examinations, including blood pressure cuffs, forehead thermometers, and dermatoscopes. Doctors can also send prescriptions to the patient’s preferred pharmacy.”

I’m a supporter of this tech trend. My docs for the last 7 or 8 years have been part of the University of Missouri Health Care system and at least half of my interaction has been on a secure online system (that includes all my records, lab reports, physician notes, etc). It’s been great. I still see my doc when necessary. I’ve been dealing with allergy and sinus issues for months and almost all of that has been online. No idea how much time that has saved me (travel, waiting room, etc) but more importantly, my physician.

Realistic-sounding speech

Just over a year ago Google presented WaveNet, a new deep neural network for generating raw audio waveforms that is capable of producing better and more realistic-sounding speech than existing techniques. It’s gotten a LOT better and is now capable of producing natural sounding human voices.

Google is using it for Google Assistant but hard for an old radio guy like me not to imagine this tech replacing radio announcers (are there still radio announcers?)

The robots are here

“My solution is that all robots must be raised for their first few years in Minnesota, where everyone is kind and generous. I assume there are other spots around the world in which the culture evolved to be unusually friendly. Part of the value of your future robot is where it was imprinted with its base personality. Someday the Minnesota Series of robots will fetch top dollar.” — Scott Adams

“When robots start doing all of the medical research, the speed of discoveries will increase a hundredfold. Robots will simply try every idea until someday there is a cheap pill that keeps your body young and healthy. The government will get out of the healthcare field when the cost of medical services becomes trivial, and I think robots will get us there.” — Scott Adams

“Spofforth had been designed to live forever, and he had been designed to forget nothing. Those who made the design had not paused to consider what a life like that might be like.” — Mockingbird (Walter Tevis)

“At some point the real cost of healthcare, energy, construction, transportation, farming, and just about every other basic expense will fall by 90% as robots get involved. It would be absurd to assume we know anything about the economy in thirty years. Nothing will look the same.” — Scott Adams

“The highest-earning professions in the year 2050 will depend on automations and machines that have not been invented yet. That is, we can’t see these jobs from here, because we can’t yet see the machines and technologies that will make them possible. Robots create jobs that we did not even know we wanted done.” — Kevin Kelly

Self-Driving Trucks

“Since early October, autonomous trucks built and operated by the startup Embark have been hauling Frigidaire refrigerators 650 miles along the I-10 freeway, from a warehouse in El Paso, Texas, to a distribution center in Palm Springs, California.”

“For now, the Embark milk runs are designed to test logistics as well as the safety of the technology. On each trip, a human driver working for Ryder (a major trucking company and Embark’s partner on this venture) heads over to the Frigidaire lot in El Paso, picks up a load of refrigerators, hauls them to the rest stop right off the highway, and unhitches the trailer. Then, a driver working for Embark hooks that trailer up to the robotruck, cruises onto the interstate, pops it into autonomous mode, and lets it do its thing. The truck mostly sticks to the right lane and always follows the speed limit. Once in Palm Springs, the human pulls off the highway, unhitches the trailer, and passes the load to another Ryder driver, who takes it the last few miles to Frigidaire’s SoCal distribution center.”
