The Fluent Digital Twin

• We at fluencyAI LLC have developed software that converts disfluent (stuttered)

speech into fluent speech.

​

• We are developing software that will allow the generated fluent speech to replace

your original, possibly disfluent speech in video-conference calls such as Zoom.

​

• Using this software, you can have a fluent ‘presence’ in Zoom despite having a

stutter.

​

• We hope to release that software in the Fall of 2025.

​

• This presentation just demonstrates how effectively our software removes

disfluencies from speech.

This presentation

• … does not illustrate the use of a Fluent Digital Twin in video-conference calls.

​

• … does illustrate the use of the FDT system to ‘sanitize’ even highly disfluent

speech.

​

The recorded speech of two people who stutter was processed by our FDT

technology, and the synthesized, fluent speech was piped to an avatar, i.e. an

animated face that appears to ‘speak’ the synthetic audio.

“So here we are in Friuli tucked away in a remote corner of the Alpine foothills in northeastern Italy at a little restaurant. I have to admit that when I travel, history is not the first thing on my mind. Food and wine are and that's what sold me on Friuli. It is famous as a source of some of Italy's best white wines.

​

We went primarily in search of wines, unaware that we soon would make a culinary detour. Occupying the extreme northeastern northeast corner of Italy, Friuli's scenery ranges from rugged coastline along the eastern border to placid plains in the west and the majestic Alps in the north where Italy butts up against Austria. Directly to the south is Venice, just a little more than an hour and a half away.

​

Though off the beaten tourist track, Friuli is hard in the path of history. Standing at one of the major crossroads between Western Europe and the east, it was conquered by just about everyone who passed by. As a result, things look different here. Rather than the familiar cultural overlay of most of Italy, the central European influence is readily apparent in Friuli.

​

The architecture tends more towards Austrian grandeur than Tuscan simplicity. Here you'll find grey stone castles rather than sun-drenched villas. The people look different too, taller and blonder than southern Italians and with plenty of German and Central European surnames.”
