How to find the best voice for your VUI (voice user interface) application

Finding a pleasant-sounding voice is key to a successful VUI interface. But it’s not always easy to get it right the first time, as proven by Apple’s move away from Siri’s first voice to a broader spectrum of voices people may like better. Many other auto manufacturers are facing the same task of replacing voices that fail to connect with the customer. Some are so aggravating that drivers turn off their system.  This reflects negatively on the manufacturer.

We think the voice should BE the voice you’d expect to hear if your car or device could talk.

An example is the voice we placed in Cadillac. Listen to her recording our world-famous    Seamless Voice Files  - six files combined to sound as smooth as if she’d recorded one sentence.

Here's how a beautiful voice looks...

How can you improve the odds of getting a voice right the first time?

In a current project for a new client, we cast 43 females from our cadre of professional Hollywood voices to find the “perfect” one. We narrowed the selections to twelve to present to the client. To help sensitize the client to the variables to listen for, we provided them with a Voice Evaluation Grid template. This helps the client listen for the qualities in the voice that will be a sustainable solution for them. Too often clients just don’t know what to listen for.
