What is AI Voice?

AI voice, often referred to as "text-to-speech" (TTS) or "voice cloning," uses algorithms and machine learning to transform written text into spoken words. Unlike traditional voiceovers done by a voice actor, AI voice is generated by artificial intelligence, offering a wide range of voice styles and accents, including a person's own voice.

Sometimes voice cloning is referred to deepfakes. Deepfakes is when human voices, using voice changers, is made to sound like someone else. For example anyone can mimic Tom Cruise’s voice or any other person’s voice and have them say anything they want.

These generated voices can be created from someone speaking or even a voice recording. As you can see, this could be problematic in the new world of AI. Which is why one should be guided by a strong moral and ethical code and also keep up with new laws to counter technological advancements.

How Much Does It Cost to Create a Custom AI Voice?

Custom AI voice pricing varies depending on the depth of customization, the AI voice generator used, and the amount of training data. Some tools offer basic text-to-speech features for free, while high-quality, custom voice cloning can cost significantly more.
