New Voice Functionality on ChatGPT

« Who Is That You Are Chatting With? Oh, Just ChatGPT.
The artificial intelligence chatbot’s Advanced Voice Mode feature has delighted some users and weirded out others.

When you think of what a voice programmed by artificial intelligence would sound like, you might picture something robotic and stilted, with a staccato cadence incapable of capturing the inflections, speed and emotion required to sound even somewhat human. But this is 2024, and the robots have gotten a serious upgrade. Now they can imitate voices, accents and intonation to an almost creepy degree — for better or worse. »

For better or worse ? The both of course.
This could probably be nice for a typical user looking for information, ordering a meal, or making a doctor’s appointment, and even support for a single person who no longer communicates with others. But it also risks generalizing deep fake vocals.
When cavemen banged stones on top of twigs to warm themselves with fire, it was a great innovation, a step forward for the human kind. And then they discovered other less positive uses…

Nexyad’s innovation, BYOD* SafetyNex, in its informative driving assistance mode for fleets and/or insurance companies, consists of warning drivers on board when they are not being prudent behind the wheel in real time. SafetyNex can then launch simple messages by anticipation such as: « slow down » or even contextualized « slow down dangerous bend », etc.
Our tool enhanced with ChatGPT-type technologies could then launch alerts such as « Honey, please slow down » in your wife’s voice, or « Daddy, go slower » in your child’s voice.
In this combination, our 100% positive innovation will make the vocal imitation for the better way.

MOTIV AI Smartphone App to Reduce Accidents for Fleets

We have developed an AI technology for vehicle fleets (trucks, cars, two-wheelers) that measures driver prudence in real time. Where our competitors measure possible indirect consequences of poor driving, such as harsh braking, we offer a real prudence metric. This metric was developed through 12 research programs co-financed by the French government, and is currently being deployed in India. The company MOTIV AI from Coimbatore has in fact developed a smartphone App based on our technology SafetyNex.
Thanks to this App, fleets reduce the number of accidents and therefore reduce their operating costs. They can also train their drivers to be more careful.

A New Paradigm For Autonomous Vehicle

When we want to automate the driving of a vehicle, it is natural to contact automation engineers. Their approach is to list the use cases. Each use case is a scenario, for example: a red vehicle follow another one blue approaching a roundabout with also a bicycle traveling in front.
The events building this scenario are: presence of a roundabout, presence of blue vehicle located in front, presence of a bicycle located in front.
Depending on the relative and absolute speed of these vehicles and their position as well as that of the roundabout (N scenarios built from these events), we deduce the desired behavior for our red vehicle to be automated.
Each desired behavior is obtained by a control law which generally includes 6 parameters. We therefore obtain 6 x N parameters just for this simple use case.
This is to be multiplied by the number of use cases. In practice, we quickly end up with a few hundred or even a few thousand parameters, which is very difficult to adjust or even impossible. And the run time of such a system requires strong embedded CPUs. It is difficult to scale.

Nexyad has developed a new approach based on a prudence metric that makes the solution scalable and which uses automation only to modulate the comfort parameters.

This approach does not work on scenarios but on events: we assign to each event a « prudence function ». In our case mentioned above, we will characterize the following events; a roundabout, a vehicle in front, a bicycle in front. This makes a total of 3 « prudence functions » (instead of N scenarios). Once these 3 events have been characterized in terms of prudence, we take into account the current scenario by combining the « prudence functions » with fuzzy logic and theory of possibilities. All possible scenarios for combining these three events are taken into account in a logical manner.

We keep only one parameter which is the « lack of prudence target », which characterizes the sportiness of the vehicle.
Prudence function are independent functions that can be tunes separately. This new paradigm reduces times of development and test/validation by a factor 100 at least.
It calculate prudence of automated vehicles (from predictive ACC to level 4). This prudence is a KPI of the vehicle.
It is an eXplainable Artificial Intelligence (XAI).
This system runs with only 5% of the CPU of a conventional PC type computer. The autonomous vehicle can at least be scalable and adjustable. This technology is called SafetyNex, to learn more: https://wp.me/p4a1CF-3ay

A NEW PARADIGM FOR AUTONOMOUS VEHICLE : reduce development, test/validation times by at least a factor 100.

WHAT IS ARTIFICIAL GENERAL INTELLIGENCE (AGI)?

This is the new concept of Artificial Intelligence described for the first time in 2007. Of course, as usual for some analysts, this AGI could surpass human intelligence, like generative intelligence and AI at all. The principle would be that these systems could have a kind of understanding and control of themselves, or a conscience, with the capacity to modify their code without human intervention.

𝗦𝗮𝗳𝗲𝘁𝘆𝗡𝗲𝘅 by NEXYAD (We Save Lives) is an ADAS tool that measures prudent driving on a scale of 0 to 100 (100 = maximum prudence, when 0 = maximum risk).

This is compliance with the road traffic code and the practices of experienced drivers. Trivial examples: we do not brush against pedestrians walking on the side of the road, we slow down before an intersection, we do not run stop signs, we adapt our inter-distance with vehicle ahead, etc. This compliance with the rules is reflected in the 𝗔𝗻𝘁𝗶𝗰𝗶𝗽𝗮𝘁𝗶𝗼𝗻 of complex situations and a speed adapted to each context. Since zero risk (or lack of prudence) does not exist, it is up to the driver or the 𝗗𝗿𝗶𝘃𝗶𝗻𝗴 𝗥𝗼𝗯𝗼𝘁 to minimize their own risks as much as possible and to anticipate possible lack of prudence by other users.

For automated/robotic driving systems, such as 𝗣𝗿𝗲𝗱𝗶𝗰𝘁𝗶𝘃𝗲 𝗔𝗖𝗖, and L3, L4, 𝗦𝗮𝗳𝗲𝘁𝘆𝗡𝗲𝘅 is set to a given prudence threshold based on the information available at any time. If the vehicle is omniscient because it is equipped with many perception organs and the road infrastructure also sends it information that is undetectable by itself, then with full knowledge of the facts the prudence threshold can be lowered. On the other hand, if the information on the road context is incomplete (for example, perception does not cover all angles around the vehicle) then the prudence threshold must be raised so that the 𝘀𝗽𝗲𝗲𝗱 𝗶𝘀 𝗿𝗲𝗱𝘂𝗰𝗲𝗱 𝗮 𝗽𝗿𝗶𝗼𝗿𝗶 in situations of contextual uncertainty.

Let us recall the definition of prudence: taking into account in one's behavior that one cannot predict or know everything, and that one cannot predict all the consequences of one's actions. Concrete example: see image below.

𝗦𝗮𝗳𝗲𝘁𝘆𝗡𝗲𝘅 𝗶𝘀 𝗮𝗻 𝗔𝗜, 𝗯𝗮𝘀𝗲𝗱 𝗼𝗻 𝗵𝘂𝗺𝗮𝗻 𝗸𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲, resulting from 15 years of R&D and 12 funded collaborative scientific programs with road safety experts, road police, professional drivers and car insurers.

SafetyNex measures 20 times per second inadequation of driving behaviour with driving context, and especially with potential dangers ahead. This inadequation level is called driving-risk and can be used both to alert driver and to act on vehicle: ACC, AD system.
