Nowadays, artificial intelligence (AI) is part of nearly every facet of our lives, both on a private and professional level. An industry that currently experiences new developments within the field of AI is that of voice overs.

In this blog post, we will dive into the differences between human and AI voices to explore the pros and cons of both.

Human voices vs. AI voices

Emotional range

  • Human voices: human voices are naturally imperfect and usually vary in tone and emotion, making them more expressive and can help bring scripts to life.
  • AI voices: AI voices are more consistent and can maintain the same tone throughout an entire script. This makes them useful for rather monotone readings such as IVRs.


  • Human voices: human voices are capable of adding a creative facet such as certain expressions, emotions or even melodies to a speech which can make it more appealing for the target audience.
  • AI voices: AI voices can help create content efficiently and consistently but clearly lack the creative facet.


  • Human voices: humans have the natural ability to understand and react to context. In terms of voiceover, human voices will therefore always be able to adjust their tone to fit the requirements of the script which can add both depth and authenticity to a recording.
  • AI voices: AI voices lack this ability making them unable to be as reactive as humans. However, they can be programmed to switch for example between accents or languages.

Turnaround time

  •  Human voices: voice overs created by human voice artists usually take time, something anywhere between hours, days and even weeks, depending on the number of words to be recorded.
  • AI voices: voice overs done by AI can be generated within a very short period of time, usually only a couple of seconds and are therefore extremely time efficient.


  • Human voices: voice overs produced by a human voice artist are usually more expensive, as you have to pay for the use of the voice artist, the equipment and a studio.
  • AI voices: AI voice overs are usually cheaper since no cost for a human voice actor, studio or equipment would apply.

Future directions

AI and specifically AI voices will continue to advance and will become more integrated into our daily lives. However, at the same time it is crucial to understand the limitations of them, especially in areas that require emotions, creativity, and authenticity.

This is why it is our goal to find a balance between human and AI voices, where both complement each other in the best possible way, so both can shine with their strengths.
