Vlastimil Gular's life took an unwelcome turn a year back: minor medical procedure on his vocal lines uncovered throat disease, which prompted the loss of his larynx and with it, his voice.
Be that as it may, the 51-year-old dad of four is as yet talking without end utilizing his own voice as opposed to the tinny timbre of a robot, because of a creative application created by two Czech colleges.
"I locate this exceptionally valuable," Gular told AFP, utilizing the application to type in what he needed to state, in his very own voice, by means of a cell phone.
"I'm not truly adept at utilizing the voice prosthesis," he included, pointing at the gap the extent of a vast coin in his throat.
This little silicon gadget embedded in the throat enables individuals to talk by squeezing the gap with their fingers to direct wind stream through the prosthesis thus make sound.
Be that as it may, Gular lean towards the new hey tech voice application.
It was created for patients set to lose their voice because of a laryngectomy, or evacuation of the larynx, a run of the mill methodology for cutting edge phases of throat disease.
The joint undertaking of the University of West Bohemia in Pilsen, Prague's Charles University and two privately owned businesses - CertiCon and SpeechTech - commenced almost two years prior.
The innovation utilizes chronicles of a patient's voice to make manufactured discourse that can be played on their cell phones, tablets or PCs through the application.
In a perfect world, patients need to record in excess of 10,000 sentences to furnish researchers with enough material to deliver their engineered voice.
"We alter together individual hints of discourse so we require a great deal of sentences," said Jindrich Matousek, a specialist on content to-discourse union, discourse demonstrating and acoustics who heads the task at the Pilsen college.
'Merely weeks'
Be that as it may, there are downsides: patients confronting laryngectomies for the most part have brief period or vitality to do the chronicles in the wake of a determination that requires quick treatment.
"It's generally only weeks," said Barbora Repova, a specialist at the Motol University Hospital, taking a shot at the venture for Charles University.
"The patients likewise need to handle issues like their monetary circumstance, their lives are flipped around, and the exact opposite thing they need to do is to make the chronicle," she told AFP.
To address these challenges, researchers thought of an increasingly streamlined strategy for the application, which is bolstered by the Technology Agency of the Czech Republic.
Working with less sentences - in a perfect world 3,500 yet as few as 300 - this technique utilizes progressed factual models, for example, fake neural systems.
"You use discourse models with specific parameters to produce combined discourse," said Matousek.
"Having more information is still better, yet you can accomplish OK quality with less information of a given voice."
The sentences are cautiously chosen and individual sounds must be recorded a few times as they are articulated distinctively alongside various sounds or toward the start and end of a word or sentence, he included.
Up until this point, the Pilsen college has recorded 10 to 15 patients, as indicated by Matousek.
Other than Czech, the Pilsen researchers have likewise made integrated discourse tests in English, Russian and Slovak.
'Infant dinosaurs'
Gular - an upholsterer who lost his employment because of his impede - figured out how to record 477 sentences over the three weeks between his conclusion and the activity.
Be that as it may, he was focused and not exactly happy with the nature of his voice.
"Throat malignant growth patients frequently experience the ill effects of some type of dysphonia (dryness) before the medical procedure, so in mix with a constrained discourse test it makes the voice sound unnatural," said Repova.
In a studio at the Pilsen college in the interim, business visionary Jana Huttova is recording freakish expressions.
The 34-year-old mother of three faces the danger of losing her voice to minor throat medical procedure - a task on her parathyroid organ.
"The Chechens have constantly favored a blade like Kalashnikov," she says, perusing from the content before her.
"I have little children and I need them to hear my very own voice, not a robot," Huttova said.
At that point she proceeded onward to her next sentence: "We were assaulted by a tyrannosaur's infant dinosaurs."
Associated with the mind
Matousek trusts that later on, patients will have the capacity to utilize the application to record their voice at home utilizing a specific site to control them through the procedure.
Furthermore, he trusts that one day it will go much further.
"A definitive vision is a smaller than expected gadget associated with the cerebrum, to the nerves connected to discourse - at that point patients could control the gadget with their musings," he said.
This sort of cutting edge arrangement is far off, said Repova.
"In any case, take a gander at cochlear inserts - 40 years prior when they began, we had no clue how it would grow, how broadly they would finish up being utilized," she stated, alluding to the inward ear inserts used to handle serious deafness.
"An upbeat end would be a gadget embedded in the throat that could chat with the patient's very own voice," she told AFP.
"It's practical: it may not arrive in a year or even in 10 years, yet it's reasonable and we're headed."
