This is a central belief in what drives us to do the work we do.

VocaliD has been at the forefront of creating custom synthetic voices using state-of-the-art machine learning and speech blending algorithms since 2014. A voice AI company with deep scientific roots, VocaliD holds innovative patents in distributed voice collection and synthetic voice aging.


It began at an assistive technology conference — Dr. Rupal Patel walked into an exhibit hall and witnessed a little girl and a grown man having a conversation using their devices, different devices… but the same voice. She looked around and was astonished to see this happening all around her — literally hundreds of individuals using just a handful of the same generic voices. Voices that didn’t fit their bodies or their personalities.

We wouldn’t dream of fitting a little girl with the prosthetic limb of a grown man, why then was it okay to give her the same prosthetic voice as a grown man?

Dr. Patel was struck by this lack of individuality and felt it was important to create a solution that would give every individual a unique voice, regardless of their vocal ability. So, with some funding from the National Science Foundation, VocaliD was born.

"Science is an incredible superpower when applied to improve the human condition."

- Rupal Patel, Founder & CEO

As a data-driven voice AI company, we bring state-of-the-art speech science to this new era in human communication and connection.

Our Mission

To enable brands and individuals to be heard in their own voices. Unique digital voices built by VocaliD uplift those who rely on assistive technologies, diversify the voices we hear in speaking devices and apps, and enable businesses to tap into the full power of voice identity.


As leaders in the voice AI market, we recognize that today’s advances in technology come at breakneck speeds. Risks come just as quickly. As with any new technology, especially one that emulates a human trait, we need to consider the unintended consequences.

While our technology provides great social benefit, we are acutely aware of and committed to our ethical responsibility. In every new advance in our technology, we are proactively creating measures to ensure that it can not be misused.
