Often it’s not exactly what you state, it’s how you say it that issues. Particularly if you are being ironical to a client service driver. Such subtlety is clearly lost on automated speech systems, more’s the pity (and, undoubtedly, on some human ears) however do not quit hope of being able to mock your future robot butler with a sassy feedback. UK start-up EI Technologies, among 17 in the current Wayra London incubator cohort, is developing a voice acknowledgment platform that can recognize emotion by analyzing vocal qualities with a precision rate it says is already much better than the average human ear.

EI Technologies’ formula analyses the tonal expression of the human voice, particularly looking at “acoustic features”, as opposed to verbal content – with the preliminary objective of powering a smartphone app that can help people track and monitor their moods. The concept for the app– which will be called Xpression, and will be introduced in a closed-alpha by the end of the year, specifically for participants of Quantified Self — is to assist “measured selfers” find out how their way of life affects their health. But its primary function is to be a test-bed to kick the tyres of the innovation, and permit EI to find out the most viable network marketing business situations for its emotional knowledge platform, says CEO Matt Dobson.

Ultimately, the startup imagines its software application having applications in vertical sectors where it could assist smooth interactions between people and machines in service circumstances, such as call centres or the healthcare space. Understanding tone can enhance automated response systems by assisting them determine when a customer is actually pleased with the response they’ve actually been offered (pushing beyond current-gen semantic keyword analysis tech that crudely sifts call transcripts for swear words or other negative signifiers). Or, in a mental healthcare circumstance, it might be made use of to assist monitor a dementia patient’s moods. A 3rd possible target market is the defense sector – it’s not tough to see use-cases around tracking soldiers’ tension levels and mental well-being, for instance.

“Initially it’s all about building awareness of ability in your possible client base,” says Dobson, describing why it plans to introduce a quantified self app 1st, rather than going straight into one of these industry verticals. “At the minute individuals do not know this kind of technology exists, and therefore how do you comprehend how it might be used? We are beginning to have those kind of chats and it’s a matter of attempting to bring it to market in a way that you can prove how excellent this innovation is, and also discover how it works well for ourselves – because there’s no benchmark out there that can tell us how excellent it should be to do this.”

Augmenting natural language processing formulas by including the ability to acknowledge and react properly to feeling, along with verbal material, seems like the natural next step for AI systems. Blade Runner‘s Replicants were naturally fatally flawed by their absence of empathy. Not that grand imagine sci-fi magnificence are at front of mind for EI Technologies at this very early phase in their development. In addition to core tech work continuing to improve their formula, their focus is necessarily on recognizing functional, near-term business opportunity chances that can take advantage of an empathy/emotional knowledge system. Which in turn suggests limiting the variety of feelings their system can pick up, and keeping the deployment scenarios relatively professional. So a compassionate Roy Batty stays a really distant – albeit tantalising – prospect.

Currently, states Dobson, their algorithm is limited to determining 5 basic feelings: happy, sad, neutral, concern and anger– with a reliability rate of in between 70 % to 80 % versus a typical human accomplishing around 60 % precision. Trained psychologists can apparently determine the proper feeling around 70 % of the time – implying EI’s formula is currently pushing past some reduces. The objective is to continue enhancing the algorithm – to eventually achieve 80 % to 90 % reliability, he adds.

The system works by searching for “vital acoustic attributes” then cross-referencing them with a type system to match the speech to among the 5 core emotions. EI’s unique sauce is equipment discovering and “a lot of maths”, states Dobson. They likewise employed U.K. speech acknowledgment expert Professor Stephen Cox, of the University of East Anglia, as a paid adviser to help make improvements the algorithm. Dobson notes that Cox has previously dealt with Apple and Nuance on their speech acknowledgment systems.

Developing the algorithm further so that it can become more nuanced– in regards to having the ability to detect a broader and more intricate spectrum of feelings than simply the core 5, such as say monotony or disgust – would definitely be a lot even more tough, says Dobson, noting that the differences between singing signifiers can be subtle. In any case, from a network marketing business perspective it makes sense to concentrate on “the big five” initially.

“It’s better to be more precise or a minimum of as precise as a qualified human, as opposed to attempting to expand your standard feelings initially,” he states. “You’ve actually got to review the value and think– there’ a value when a procedure can tell somebody’s snapping with it. Whereas where’s the value in understanding the difference between boredom and unhappiness or loneliness? It becomes a bit less apparent when you begin to look at it.”

(Philosophers and sci-fi followers could disagree of course.)

EI Technologies isn’t the only start-up in this area. Dobson mentions Israeli startup Beyond Verbal as one of a handful of rivals– but notes they’re targeting a somewhat various outcome, looking for to recognize how someone wishes to be viewed, as opposed to concentrating on their immediate “emotional layer”. He likewise points out MIT spin-out Cogito as an additional business working in the emotional intelligence space.

One means EI Technologies is differentiating from rivals is by its objective to have its system work on the customer device, rather than using cloud processing which requires connection to function. That’ll then release it approximately be deployed in a range of gadgets– not simply smartphones but other gadgets such as cars where cellular connectivity is not always an offered, says Dobdon.

The startup, which is in the middle of its stint at Wayra London, is backed by around ₤ 150,000 ($230,000) in seed financing– which includes Wayra’s investment as well as finance from the UK government’s Technology Technique Board. Dobson says it’s planning to raise an additional round of financial investment in February next year, unless a VC comes calling faster.”If we’d leading up finance just now we could increase our program,” he adds.
