Artificial speech generally is a fearful object today when paired with deepfakes and different AI deceptions, however it’s additionally an indispensable device for anybody who can now not converse on their very own. Acapela Group has these of us squarely in thoughts with its new “my own voice” service, which lets anybody train an AI voice profile totally free.
Acapela has been within the text-to-speech house for round 25 years and was just lately acquired by tech accessibility big Tobii Dynavox, although they nonetheless function independently.
Like many industries, accessibility has been closely influenced by the appearance of consumer-scale machine studying processes. Seven or 8 years in the past, Acapela co-founder Remy Cadic remembers, it was not simply tedious to customise an artificial voice for your self, however the outcomes weren’t significantly good.
“It was very time consuming — the affected person needed to prepare for 8 hours. Now we are able to financial institution a voice with simply 50 sentences recorded; it takes about 10 minutes and the voice is prepared the subsequent day,” he stated. “There’s undoubtedly a revolution occurring with neural text-to-speech methods.”
Having a speech generator that makes use of one’s personal voice is actually one thing a rising variety of folks can admire — selecting from an inventory is a bit dehumanizing. Many have voices they might reasonably use, however it wasn’t till just lately that it was an choice.
They weren’t kidding about how fast and straightforward it’s: I went by means of the brand new “my very own voice” course of, and it actually was simply 50 quick sentences, drawn from a (random, it appeared) corpus of novels, recipe books, and articles. The recording interface was easy and straightforward to navigate, and positive sufficient, a day or so later my voice was prepared to make use of. The standard is okay — not uncanny like some fashions on the market could be, however clearly my very own voice (as marketed) and in a position to deal with any sentence I threw at it within the demo web page.
Now that it’s there, if I ever want it I can go and obtain it for a payment to make use of on any suitable speech-generation system. Clearly this contains Tobii Dynavox’s TD Discuss and units; the corporate just released a new one last week, in reality — this stuff are getting fairly glossy.

And that’s the true level of all this — it’s not a technical demonstration of the facility of neural voice tech or a demo that lets anybody feed it a star voice to clone. It’s a device made particularly for individuals who till just lately might have had no choices or at finest a troublesome, advanced course of in the event that they wished to protect their voice.
Many going through degenerative circumstances, most cancers, or sure procedures know that inside a number of months or years they might not be capable of converse properly or in any respect anymore. Making the method of banking their voice as straightforward as potential is a service many will admire.
“One large benefit is we additionally customise for kids — we’ve made the recording script simpler to learn, and tuned the system to make the standard of youngsters’s artificial voices higher. We have been the primary on this planet to try this, and we’re nonetheless going on this route,” stated Cadic.
With the ability to report and re-record or artificially age the banked voice is a brand new and difficult functionality, however one which appears to be getting outcomes:
The compatibility with offline units that don’t have the newest neural processing chip is a key differentiator as properly. “There are on-line options the place it’s straightforward to create a voice, however it’s solely out there through the cloud, and that’s simply not sensible,” he stated.
By the way, whereas the 50-sentence factor is nice for people who can nonetheless learn and converse, a voice can be skilled on voice recordings from individuals who have since misplaced that potential — it simply isn’t fairly so easy.
The corporate has additionally discovered that range and thoughtfulness within the coaching course of is as vital as in different AI purposes. Cadic identified that a problem with some super-fast coaching methods is that “it would just about simply attempt to discover the speaker within the coaching materials that’s closest to the consumer. But when there isn’t a speaker within the coaching near the unique voice, it simply gained’t sound prefer it.”
Acapela product supervisor Nicolas Mazars added that, like many AI issues with their root in inadequate coaching information, this one just isn’t evenly distributed: “That course of works properly for the typical 50-year-old white man, however not should you’re an African-American man, otherwise you don’t converse English properly. We work in 23 languages, and have many customers who’ve disabilities. We attempt to depend on consumer suggestions and develop one thing for them, by them.”
The recording and banking course of is free; you can sign up for an account here and prepare your individual artificial voice in minutes. You solely pay if you wish to obtain and set up it on a tool.
