The Claim

Cloned voices exhibit significantly reduced variation in speech segment length and a higher proportion of speaking time relative to authentic voices, reflecting a lack of natural biological interruptions such as breathing and cognitive pauses.

Description
1 study reviewed
In plain English

Cloned voices have less variation in how long each speech segment lasts and spend more time speaking than real human voices, because they lack natural pauses like breathing and thinking.

See the scientific wording

Cloned voices show significantly reduced variation in speech segment length and higher proportion of speaking time compared to authentic voices, indicating a lack of natural biological interruptions such as breathing and cognitive pauses.

Why this might work

Cloned voices do not breathe or think, so they do not pause to take air in or process what to say next. This makes their speech continuous and evenly spaced, unlike real human speech which naturally breaks for breathing and thinking.

  1. Study: Investigation of Deepfake Voice Detection Using Speech Pause Patterns: Algorithm Development and Validation

    AI voices sound more robotic because they don’t need to breathe or think like humans, so they talk longer without pauses. This study proved that by showing AI voices have fewer and more regular pauses than real people.
