How I will test them

I will copy&paste the following text to all AI and put the results here so you can also review by yourself which one convinces you more:

Hello everyone, I’m testing this AI voice to see how natural, expressive, and realistic it sounds. Can you tell if I’m human? Let’s find out! The quick brown fox jumps over the lazy dog — a classic sentence that uses every letter in the alphabet. But that’s just the beginning. Let’s try some tricky sounds: “She sells sea shells by the sea shore.” Now something softer: “The sky was a deep, tranquil blue as the sun set over the hills.” Can the voice change pace? Let’s slow down… and now speed up! How about tone? Let’s try a happy sentence: “Wow! I just won the lottery!” And now a sad one: “I’m really sorry, but things didn’t work out.” Emotions matter. A good voice generator should sound excited, calm, serious, playful — and everything in between. Finally, let’s check pronunciation: “Schedule,” “Entrepreneur,” “Anemone,” “Colonel,” “Worcestershire,” “Quinoa.” Tricky, right?

It’s not bad, but it’s easy to tell it’s not a human — it lacks some emotion. In the pro version, there’s an option to ‘try a realistic voice’, though I’m not sure how good it is.

  1. Great breakdown. I think using a script with varied pacing and emotional tones is such a smart move — it mirrors real-world use so much better than just reading flat text.
